Introduction The Series 9900 RF Signal Manager is a family of products designed to simplify the complex RF networks that support key services in HFC system headends and hubs. A family of passive signal splitting and combining modules support both forward (50-1000 MHz) and reverse (5-70 MHz) path applications. A family of active devices provide a low-cost, high-quality solution to isolation and gain requirements.

The Series 9900 module packaging allows for maximum product density without exceeding normal practices for accessibility and maintenance. In addition to the modules themselves, the Series 9900 RF Signal Manager system provides a chassis/rack mounting system that fits the architecture of typical CATV headends and hubs. This system provides easy access to each module as well as methods of identifying its dedicated use in the network. Emphasis has been placed on the ability to build flexible networks with ease of maintenance and accessibility to the modules and interconnecting cables.

The Series 9900 passive devices provide bi-directional splitter/combiner and directional coupler components that mount easily in a multifunction chassis. Each forward or reverse module is available in 2-, 4-, and 8-way versions. Directional couplers (10 dB and 20 dB) are also available to provide low loss signal sampling or test point access anywhere in the network. Each module offers superior electrical specifications compared to generic splitter/combiner components and is packaged to ensure outstanding RF integrity. The 4-way and 8-way versions use plug-in attenuator pads for enhanced signal balancing.

The Series 9900 active devices provide a low-cost, high-quality solution to isolation and gain requirements for new design HFC networks. Active modules include an insertion amp, power amp, high gain combiner amp, reverse amp, and triple A-B switch. Features take advantage of the RF Signal Manager platform’s mounting density and cable management. Specific features include a (dry contact) status monitoring port, a redundant powering scheme, high-pass filters for narrowcast use, 20 dB test points, and very high isolation. Active modules use plug-in attenuators and equalizers to optimize isolation, gain, and signal response.

Module Functional Descriptions

591772 Rev G 7


Splitter/Combiners There are 2-way, 4-way, and 8-way bi-directional splitter/combiners designed to operate in the 5 MHz to 70 MHz range or in the 50 MHz to 1 GHz frequency range. All are available with F-type or BNC-type coaxial connectors.

The 2-way devices have two electrically separate devices contained in a single wide module. The 4-way splitter/combiners are also contained in a single wide module. The 8-way splitter/combiners are housed in a double wide module, which occupies the same space in the chassis as two single wide modules.

Attenuators Plug-in attenuators for balancing incoming signals can be installed in the 4-way and 8-way splitter/combiners by headend personnel. These passive modules come with 0 dB attenuators installed. Attenuators (pads) of other values (1 dB to 20 dB) are available. Refer to Appendix A for a list of attenuator part numbers.

Directional Couplers 10 dB and 20 dB directional couplers have two electrically separate devices contained in a single wide module. They are available with F-type or BNC-type connectors.

Directional couplers can be used with a spectrum analyzer to monitor signals at any point in forward or reverse path.

Directional couplers can also be used as a pair of 2-way splitter/combiners that provides 10 dB or 20 dB attenuation on signals to the 1-T or 2-T ports as compared to the 1-I and 2-I ports.

Insertion Amp Insertion amps have a double duty to provide high isolation between like frequencies when used with “zoning” or “narrow-casting” applications and to provide up to 19 dB of gain when required to drive forward fiber optics, etc. Another application of this product is to act as the first gain stage for the power amp module, if required.

Power Amp The power amp is designed to work as a low-distortion, high-power amplifier. Designing a combining and splitting network up to 1000 MHz that drives many fiber optic transmitters requires compensation for a lot of insertion loss. The power amp module can provide the RF power required to meet that requirement. It can be a standalone amplifier or used in conjunction with the insertion amp module to act as a gain stage.


591772 Rev G 9

High Gain Combiner Amp The high gain combiner amp provides a way to isolate two narrowcast inputs (VOD and Data, for example) or one broadcast and one narrowcast feed. The high output feature supplies a certain degree of gain that is needed when trying to meet the higher drive requirements of the new media (narrowcast) ports on some fiber transmitters.

Reverse Amp The reverse amp provides isolation and minimum gain for applications in the reverse (5-200 MHz) path.

Triple A-B Switch The triple A-B switch provides three 2-port switches, each individually controlled via two pins (CNTRL/GND) of a contact closure. Color status LEDs convey the "set/reset" condition of the individual switches. This module facilitates setting up backup operations for the active RF Signal Manager modules. An optional RF Detector module provides an internal trigger mechanism for the switches which provides a simple, cost effective, solution for many RF redundancy applications.


10 591772 Rev G

Attenuators Plug-in attenuators for optimizing isolation and gain can be installed in the active modules by headend personnel. The modules come with 0 dB attenuators installed. Attenuators (pads) of other values (1 dB to 20 dB) are available. Refer to Appendix A for a list of attenuator part numbers.

Equalizers Plug-in equalizers are available for the active modules to optimize signal response and compensate for tilt that can possibly occur in the aggregate signal path of the combining network.

Equalizers are available in 1.5 dB increments up to 9.0 dB. Refer to Appendix A for a list of equalizer part numbers.

High Pass Filters High pass filters are available for 450 MHz, 550 MHz, and 650 MHz to limit out of band noise/distortion. They provide 20+ dB of lower band noise attenuation when amplifiers are used in narrowcast applications.

Power Supplies Power supplies are available in both 120/240 volt AC and -48 volt DC versions. The AC power supply will be made in two versions, Class I and Class II, for international and consumer requirements. The power supplies mount to the back of the RF Signal Manager chassis using a bracket, and as such, do not take up a chassis mounting slot normally used for passive or active products. An optional redundancy scheme allows for two power supplies to be connected in parallel to provide backup in case one fails. All power supplies are equipped with an external, NEBS compliant, grounding stud.

Introduction The Series 9900 RF Signal Manager is a family of passive bi-directional splitter/combiners and directional couplers plus insertion, power, combiner, and reverse amps for use in source/hub hybrid fiber/coax (HFC) distribution systems. All components are contained in die cast modules. Modules are available with BNC or F-type connectors.

The Series 9900 module packaging allows for maximum product density without exceeding normal practices for accessibility and maintenance. In addition to the modules themselves, the Series 9900 RF Signal Manager system provides a chassis/rack mounting system that fits the architecture of typical CATV headends and hubs. This system provides easy access to each module as well as methods of identifying its dedicated use in the network. Emphasis has been placed on the ability to build flexible networks with ease of maintenance and accessibility to the modules and interconnecting cables.

The modules easily install in a chassis that is mounted in a standard EIA 4-post rack, or in a relay rack, and occupies 4 RU of vertical space.

Scope of This Chapter This chapter explains how to configure Series 9900 active and passive modules and install them in the Series 9900 Chassis.

Preparing to Mount Passive Modules in the Chassis

591772 Rev G 39


Introduction You can insert any combination of active and passive modules in a Series 9900 Chassis. The chassis has slots for 16 single wide modules. The chassis also accommodates double wide modules, which take two slots each.

Considerations Prior to Installing Passive Modules Before installing 4-way or 8-way splitter/combiner modules, you need to do the following:

Balance the signals for all input/output ports of the module by using internal, plug-in attenuators. See Changing Attenuators below.

We recommend inserting an internal plug-in 75 ohm terminator for any connector in the module which is not being used to carry a signal.

Changing Attenuators 4-way splitter/combiner modules have a removable cover on one side, which is attached by four captive screws. A label on the outside of the cover enables you to mark the value of the plug-in attenuator (pad) for each port. 8-way splitter/combiners have removable covers on both sides, for accessing 4 pads on each side. Attenuators are available in values from 1 dB to 20 dB. The attenuation value (in dB) of each pad is indicated on top of the pad.

Changing Attenuators in a Module Already Installed and Wired The chassis is designed so that you can change attenuators in a module that is already mounted and wired, without disconnecting the coaxial cables connected to the module. Loosen the captive screw that attaches the module to the chassis and pull the module forward, so that you can access the module side cover.

Procedure for Changing Attenuators Follow these steps to change attenuators. 1 Use a spectrum analyzer to measure the incoming signals or the outputs and

determine the amount of attenuation needed on each port. 2 With your fingers, unscrew the captive screws and remove the module side

cover from the module.


40 591772 Rev G

CAUTION:

To prevent electrostatic damage to electronic components, take ESD precautions, including the use of an ESD wrist strap.

CAUTION:

Do NOT remove the metal cover on 2-way splitter/combiners or on directional couplers.

3 Pull out any attenuator (pad) of the wrong value and replace it with an attenuator of a value (in decibels) that will balance the input. Push in the replacement attenuator until it stops. Remove and insert the attenuators with your fingers, no tools are required. It does not matter which way the pad is inserted, just that the three pins go into the three holes.

CAUTION:

Do NOT remove the plastic attenuator guide/cover (through which the attenuators insert).

4 Mark the values of the attenuators on the label of the module side cover, with a

very fine tipped felt pen.


591772 Rev G 41

If the ink is water soluble, you can use a damp cloth to remove it when changing attenuator values. Permanent felt pen ink can be removed using methyl alcohol.

5 Re-attach the module side cover and tighten the captive screws.

Note: Torque the screws to 10 to 15 in-lbs (1.13 to 1.70 Nm).

75 W Internal Terminator We recommend terminating any unused ports on the 4-way and 8-way splitter/combiners that are not connected to signal cables. Use a 75 Ω resistor to prevent signals reflecting. Instead of using external terminators on unused ports, you can use the 75 Ω internal terminator (part number 574496) for such ports. Remove the attenuator for the unused port and replace it with an internal 75 Ω terminator.


42 591772 Rev G

Preparing to Mount Active Modules in the Chassis

Introduction You can insert any combination of active and passive modules in a Series 9900 Chassis. The chassis has slots for 16 single wide modules. Active modules are all double wide modules, which take two slots each.

Considerations Prior to Installing Active Modules Before installing an active module, you need to do the following:

Use internal plug-in attenuators of the correct value for your specific system design to optimize isolation and gain, without compromising distortion and noise performance.

Use internal plug-in equalizers of the correct value for your specific system design to optimize distortion performance and compensate for tilt that can possibly occur in the aggregate signal path of the combining network.

Use internal plug-in high pass filters of the correct frequency for your specific system design to limit out-of-band noise/distortion.

Changing Attenuators, Equalizers, and High Pass Filters Active modules have a removable cover on one side, which is attached by four captive screws. A label on the outside of the cover enables you to mark the value of the plug-in attenuator(s), equalizer(s), or high pass filer(s). Attenuators are available in values from 1 dB to 20 dB. The attenuation value (in dB) of each pad is indicated on top of the pad. Equalizers are available in values from 0 dB to 9.0 dB in 1.5 dB steps. The value in dB is indicated on the top of the equalizer. High pass filters are available in three frequencies; 450 MHz, 550 MHz, and 650 MHz.

Changing Attenuators, Equalizers, and High Pass Filters in a Module Already Installed and Wired

The chassis is designed so that you can change attenuators and equalizers in a module that is already mounted and wired, without disconnecting either the coaxial cables connected to the module, or the power cables connected to the active modules. Loosen the captive screw that attaches the module to the chassis and pull the module forward, so that you can access the module side cover.

Procedure for Changing Attenuators, Equalizers, and High Pass Filters Follow these steps to change attenuators, equalizers, and high pass filters.


591772 Rev G 43

1 Determine the correct values of attenuators, equalizers, or high pass filters to install in each module for your specific system design.

2 With your fingers, unscrew the captive screws and remove the module side cover from the module.

CAUTION:


3 Pull out any attenuator (pad), equalizer, or high pass filter of the wrong value and replace it with one of the correct value for your specific system design.

CAUTION:

Do NOT remove the plastic guide/cover (through which the attenuators insert).

Note: Remove and insert the attenuators, equalizers, and high pass filters with your fingers, no tools are required. Carefully insert replacements until they stop. It does not matter which way an attenuator is inserted, just that the three pins go into the three holes. Equalizers and high pass filters only fit into their socket in one orientation. Be sure to line up the pins correctly.


44 591772 Rev G

Note: This previous example shows a Model 9954H High Gain Combiner Amp. The following example shows a Model 9950I Insertion Amp. Other active modules are similar.

4 Mark the values of the attenuators and equalizers on the label of the module side

cover, with a very fine tipped felt pen. If the ink is water soluble, you can use a damp cloth to remove it when changing values. Permanent felt pen ink can be removed using methyl alcohol.


591772 Rev G 45

Note: These examples show labels for the Model 9954H and Model 9950I. Other active modules have similar labels.

5 Re-attach the module side cover and tighten the captive screws. Note: Torque the screws to 10 to 15 in-lbs (1.13 to 1.70 Nm).

Power Supply Mounting Procedure

Power Supply Models RF Signal Manager active modules require a 29 V DC power source. Three different power supply models are available, as follows:

Model 9960AC: Class II, AC to DC

Model 9961DC: DC to DC

Model 9962AC: Class I, AC to DC

Notes:

Power supplies are equipped with external, NEBS compliant, grounding studs.

One power supply can provide power to all eight active modules in the chassis. A second power supply (for backup power) can be mounted in the same chassis.

Power supplies are attached to the back of the RF Signal Manager module chassis with a supplied mounting bracket.

Power supplies can be installed on the chassis in such a position to physically span two active modules and therefore provide cooling airflow over both module’s heat sinks from the power supply’s internal cooling fan.

Power supply dimensions: Width: 2.5 in. (63.5 mm), Height: 4.5 in. (114.3 mm), Depth: 7.5 in. (190.5 mm)


591772 Rev G 47

Power Supply Power Cords The power cord for the power supply is selected according to the country of destination and must be used in order to comply with local safety requirements. Use the following guidelines if it is necessary to replace the power cord set.

The female receptacle of the power cord set must comply with the CEE-22 requirements, and will look like Figure 1.

For the United States and Canada In the United States and Canada the male plug is NEMA 5-15P style as shown in Figure 2, and it is UL listed and CSA certified. The power cord set must be selected according to the current rating for your unit. Please consult the table below for the selection criteria for power cords used in the United States and Canada.

Cord Type

Size of Conductors in Cord Maximum Current Rating of Unit

USA Europe USA Europe

SJT 18 AWG 3x0.75 mm2 10 Amps 6 Amps

SJT 16 AWG 3x1.00 mm2 12 Amps 10 Amps

For European Countries In Europe you must use a certified (HD-21, PVC insulated) power cord set that is appropriate for the receptacle in your country. The cord set is HAR certified, and the mark “HAR” will appear on the outer sheath along with a safety certification agency name or symbol. For Germany you must use a power cord set with the following specification: HO5VV-F, <HAR>, PVC, 3x0.75 mm2. The power cord set must be selected according to the criteria for power cords used in Europe.

Note: Contact Cisco Services, or other assistance center, for more information.

Installing Power Supplies in the Chassis Follow these steps to install a primary and optional backup power supply in the RF Signal Manager chassis. 1 Attach the power supply mounting brackets to the power supply as shown.


48 591772 Rev G

Important: Tighten all screws securely except the two screws in the slotted screw holes in the top mounting bracket. Torque the screws to 10 to 15 in-lbs (1.13 to 1.70 Nm). The top bracket needs to be temporarily tilted down during installation on the chassis. Note: The bottom bracket should be installed so it is parallel to the bottom of the power supply, i.e. not tilted up or down.

2 Tilt the top mounting bracket down on the end with the slotted screw holes until it stops against the screws. Then position the power supply with bracket on the back on the chassis as shown. Note: Position the mounting bracket to approximately span two active module mounting locations in the chassis. Important: The recommended mounting position for power supplies is behind any two of the four center module mounting positions in the chassis.


591772 Rev G 49

a Engage the bottom bracket hanger on the chassis lip first, then insert the top

bracket under the top chassis lip as shown above and lift up on the bracket to engage the lip on the chassis.

b Pull up on the top mounting bracket with your fingers while pushing down on the back of the power supply with your thumb to put some flex tension on the mounting bracket.

c While holding the bracket up and power supply in this position with tension, tighten the two top mounting bracket screws.

3 Temporarily insert two active modules in the chassis from the front and adjust the position of the power supply and mounting bracket (side-to-side) so it is centered across the width of both modules.


50 591772 Rev G

Note: Make sure that all screws are now secure. Torque the screws to 10 to 15 in-lbs (1.13 to 1.70 Nm) Important: Check to make sure that the power supply is held securely in place by the mounting brackets. If not, repeat steps 2b and 2c to obtain sufficient flex in the mounting brackets for a secure fit. Result: The primary power supply is installed in the chassis.

4 Important: Ground the power supply by attaching a grounding lug and cable to the NEBS compliant grounding lugs provided on power supply.

5 Connect the approved power cord to the power supply. Important: Do NOT connect the power supply power cord to its power source at this time. Wait until after all modules are installed, and all module signal and power cables are connected, before attaching the primary and backup power supply power cords to their respective power sources.

6 The following illustration shows a second backup power supply mounted in the chassis. Repeat steps 1 through 5 to install the backup power supply, if used in your application. Note: Due to side-by-side mounting, an offset screwdriver is required to tighten the mounting screw(s) located on the side next to the primary power supply.


591772 Rev G 51

Result: The backup power supply is installed in the chassis.

7 Follow the procedures in Installing Modules in the Chassis (on page 54) to install the modules in the chassis.

8 Follow the procedures in Routing and Connecting Active Module Power Cables (on page 59) to connect primary power, and backup power if used, to all active modules in the chassis.

Optional Cooling Fan Mounting Procedure

Introduction Optional cooling fans are available if additional module cooling is desired for mean time between failure enhancement. Use RF Signal Manager Cooling Fan Kit, part number 4000059.

Cooling fans can be installed on the back of the RF Signal Manager chassis in such a position to physically span two active modules and therefore provide additional cooling airflow over both module’s heat sinks.

Note: Cooling fans receive their power from an active module power supply.

Installing Module Cooling Fans in the Chassis Follow these steps to install optional cooling fans in the RF Signal Manager chassis. 1 Follow the instructions in the Power Supply Mounting Procedure (on page 46)

section in this manual to install the desired active module power supplies. Note: Power supplies should be installed to cool two active modules each.

2 Determine the remaining active modules in the chassis (not cooled by power supply fan exhaust) for which you want to provide additional cooling.

3 If possible, pair these remaining modules to be cooled by one cooling fan. 4 Attach the cooling fan module to the rear of the chassis as shown with the power

connector facing the back of the chassis. Note: The fan housing has a lip on its front edge that is a press fit over the metal lip on the bottom of the chassis.

Optional Cooling Fan Mounting Procedure

591772 Rev G 53

Note: Position the cooling fan module so that it physically spans two active modules to be cooled, if possible.

5 Mount the active modules in the chassis and check the cooling fan position to see that it forces air over both module’s heat sinks. See the procedures in Installing Modules in the Chassis (on page 54) for instructions on mounting modules.

6 Follow the procedures in Routing and Connecting Active Module Power Cables (on page 59) to connect power to the cooling fan(s).


54 591772 Rev G

Module Mounting Procedure

Introduction After each individual module is prepared for installation, you are ready to install the modules in the chassis, route the signal cables through the chassis to the modules, and connect the active module power cables.


Important: For Europe installations, the installer should review EN 50083-1 /A2:1998 and install this product per EN 50083-1/A2:1998.

Installing Modules in the Chassis Follow these steps to install RF Signal Manger modules into the chassis. 1 Insert a module into the chassis with the connectors facing the front of the rack.

Note: The round stud on the bottom of the module fits into a matching hole in the front of the floor of the chassis. Double wide modules have two round studs.

2 Label the cables. Note: Make sure that you do not attach the labels to the part of the cable that you will cut off in step 3.

3 Cut each cable to length, so it can curve loosely up around the cable dressing rod to its connector on the front of the module. See the illustration in Routing Signal Cables (on page 56). Important: Do not attach the cables to the cable dressing rod, you will need to be able to pull modules from the chassis without disconnecting their cables, for the purpose of changing attenuators and/or equalizers.

4 Attach a BNC or F-type connector to the end of the cable, depending on the type of connector on your particular modules.

5 Attach the BNC or F-type connector to its correct port on the module. Note: The module can be in or out of the chassis when you attach the connectors to its ports.

6 Use the captive screw on the faceplate of the module to secure the module to the chassis. Double wide modules use two captive screws. Note: Tighten the screws to 9 in-lb (1.0 Nm).

7 Repeat steps 1 through 6 to install the remaining modules in the chassis. 8 Secure the cable tie at the back of each cable channel around the cables passing

through that channel. See the illustration in Routing Signal Cables (on page 56).

Module Mounting Procedure

591772 Rev G 55

9 On the paper template, which is kept in the pull plate under the cable tray assembly, record information identifying all of the cables for every module mounted in the chassis.

10 Connect module power cables to all active modules in the chassis. Note: Follow the procedures in Routing and Connecting Active Module Power Cables (on page 59) to connect primary power, and backup power if used, to all active modules and optional cooling fans in the chassis.

11 Connect the primary power supply, and backup power supply if used, power cords to an approved power source of the proper rating for the power supply. Note: Do not power up the chassis until after all modules are installed, and all module signal and power cables are connected.

Routing Signal and Power Cables

Active Module Front Panel Connectors The following diagram shows the front panel connector layout on a Model 9950I Insertion Amp and a Model 9958SF Triple A-B Switch. Other active modules have similar connectors.

Routing Signal Cables You can feed cables to the chassis from above or below. There are eight cable guides that attach to the angle brackets. Normally the cables for two adjacent single wide modules or one double wide module would pass through a cable guide, then from back to front through a cable channel, loop upwards around the cable dressing rod, and to the F-type or BNC connectors on the front of the modules in the chassis.

Four cable guides and eight cable guide mounting screws are packed with each angle bracket. If you are wiring from above, attach the guides at the top of the angle bracket and if wiring from below attach the guides at the bottom of the angle bracket.


591772 Rev G 57

You will need sufficient cable length to pass through the cable guides, along the cable channels, around the cable dressing rod and to the connectors on the modules. The purpose of the cable dressing rod is to enable you to remove a module from the chassis and pull it forward enough to change attenuators or equalizers in the module without disconnecting the cables connected to the module.

Cables for two single wide devices or one double wide device should pass through one cable guide and one cable channel, underneath the cable dressing bar, as shown in the following illustration.

Note: The illustration above shows the module chassis separated from the cable tray assembly in order to better illustrate the signal cable routing. In an actual installation, the module chassis will already be attached to the cable tray assembly.

Signal Cable Connector Considerations Signal cable connectors must meet certain specifications to ensure that signal quality is maintained.

F-Type Connectors Observe the following specifications for F-type connectors.


58 591772 Rev G

CAUTION:

To ensure a good connection and avoid damage to F-type connectors, coaxial cable used with F-type connectors must have a center conductor between 0.022 and 0.042 inches (0.56 mm to 1.07 mm) in diameter. The center conductor must NOT project more than 0.375 inch (9.5 mm) from the cable jacket where it enters the connector.

CAUTION:

Do not over tighten F-type connectors! Tightening past 30 in-lbs (3.39 Nm) of torque can cause damage to the F-type connector ports.

BNC Connectors Observe the following specifications for BNC connectors.

CAUTION:

If using BNC connectors, use only 75 Ω Ohm BNC connectors with RF Signal Manager. Do NOT use 50 Ω BNC connectors. You can identify a BNC connector by looking at the end of the connector:

50 Ω BNC connectors have a white Teflon dielectric sleeve between the central and outer conductors.

75 Ω BNC connectors have only air as the dielectric between the central and outer conductors.


591772 Rev G 59

Routing and Connecting Active Module Power Cables The following illustration shows how to daisy-chain the module power cables to provide power to each active module and optional cooling fan in the chassis.

Note: If both primary and backup power supplies are used, there would be another set of daisy-chained module power cables running from the backup power supply to the backup power connectors on each active module.

Important:

Module power cables are designed to route power to modules in the same chassis that contains the power supply. Therefore, group your active modules in the chassis that contain the power supplies. Module power cables are not designed to route power to modules mounted in chassis in other locations in the rack.

The recommended maximum power cable daisy-chain is one that connects eight active modules, plus two optional cooling fans, in the same chassis.

View of Installed Modules With Power Cables Connected The following illustration shows the installed active modules from the front of the chassis, with power cables from the primary power supply connected to the modules.


60 591772 Rev G

Notes:

If a backup power supply is installed, there will be a second set of power cables running from the backup power supply to the backup power input connector on each active module.

Module power cables are available in white and black. Use the standard white power cables for routing primary power. Use the black power cables in the Backup Power Cable Kit, part number 4000060, for routing backup power.

The following illustration shows:

Installed active modules from the rear of the chassis

Power cables from the primary power supply routed to the modules

An optional cooling fan installed

A backup power supply installed, but no power cables connected


591772 Rev G 61

Note: The standard white power cables are used for routing primary power. Use the black power cables in the Backup Power Cable Kit, part number 4000060, for routing backup power from the backup power supply to the active modules.

Triple A-B Switch Operation

Overview The Triple A-B Switch provides three 2-port switches, each individually controlled via two pins (+/Gd) of a contact closure on the front panel terminal block. Color status LEDs convey the "set/reset" condition of the individual switches. This module facilitates setting up backup operations for the active RF Signal Manager modules. An optional RF Detector module provides an internal trigger mechanism for the switches which provides a simple, cost effective, solution for many RF redundancy applications.

Each individual control pin pair can be ganged with any combination of the other two pairs via internal dip switch configuration. This relieves the need for external jumpers when one control pair needs to switch more than one switch.

In-system switch failure redundancy is provided by a hot swappable PS and control board interfacing three passive latching relay switch boards causing no interruption to the current switch status when removed. "Set" state conditions are controlled by ground potential at the CNTRL pin. "Reset" is controlled by open circuit. An equalizer/filter socket is provided in the primary path along with a pad socket in the backup. A 2-pin normally open contact closure alarm interface is ROSA connectible and alarms on the status of the PS/Control board and power input condition.


591772 Rev G 63

The design of the switch includes plug in modules capable of RF detection, RF level detection, and other future requirement of signal monitoring. These modules will connect to the switch control inputs and be capable of driving the switch set/reset conditions.

Indicator LED Color Codes The four indicator LEDs on the front panel of the Triple A-B Switch are tri-state LEDs which are capable of displaying three different colors. The color displayed depends upon the switch or alarm state for a given input. See the following table for an explanation of LED colors and operating states.

LED\Color Green Orange Red

Pwr OK - Dual PS environment

Supply failure - Dual PS environment

N/A

Sw3 OK Backup mode via external contacts

Switch Control and Position Matrix The following charts show the switch control and positions for various operating modes.

Note: The Model 9958 Triple A-B Switch comes from the factory set in default mode. In default mode all three switches (Sw1, Sw2, and Sw3) in the module are "ganged". Ganged means that switching any one of the three switches causes all three switches to switch.

RF Detector Module Introduction The RF Detector module is a field-installable, plug-in module that provides an internal trigger mechanism for the Triple A-B Switch module's internal switches. It provides a simple, cost-effective solution for many RF redundancy applications.

The following illustrations show the top and side of the RF Detector module.


72 591772 Rev G

Functional Description The RF Detector module contains:

A 2-position selector switch, marked Reset and Ready/Set

Two LEDs, LED A (right) and LED B (left)

The LEDs indicate various operating status, as follows.

LED LED Condition Status

A (right) RF Level

Flashing Green RF Detector is plugged in and powered, but RF level is outside the safe operating range of the RF Detector.

A (right) RF Level

Solid Green Connections have been made to the Triple A-B Switch and the RF level is within the safe operating range of the RF Detector.

B (left) Ready/Set

Flashing Green Alarm condition. RF level has dropped by -6 dB from "set point".

B (left) Ready/Set

Solid Green The RF Detector has been switched to the Ready/Set position and the RF input level has been "set".

Note: "Set" means that the current RF input level has been read and stored in the RF Detector's nonvolatile memory.

Installing the RF Detector Modules The Triple A-B Switch contains three internal switches as indicated by the labels on the module side covers. Switches SW1 and SW2 are located under the right side cover. Switch SW3 is located under the left side cover.

Complete the following steps to install RF Detector modules in the Triple A-B Switch. 1 Unscrew the five cover screws that hold each side cover on the Triple A-B Switch

module. Note: The right side cover uses captive screws. The left side cover screws are non-captive screws.

CAUTION:

To prevent electrostatic damage to electronic equipment, take ESD precautions, including the use of an ESD wrist strap.

2 Use the following illustrations to locate and remove the equalizers from each

individual switch for which you plan to install an RF Detector module. Note: No tools are required. Pull straight up on the equalizers with your fingers to remove them.


591772 Rev G 73

Right Side Cover The following illustration shows equalizer location and removal under the right side cover.


74 591772 Rev G

Left Side Cover The following illustration shows equalizer location and removal under the left side cover.


591772 Rev G 75

3 Insert the RF Detector modules into the same locations as the equalizers. Note: The RF Detector module must be inserted in the proper orientation as shown in the following illustrations. Right Side Cover The following illustration shows RF Detector module installation under the right side cover.


76 591772 Rev G

Left Side Cover The following illustration shows RF Detector module installation under the left side cover.

4 Reassemble the module side covers and tighten the five cover screws. Note: Torque the screws to 10 to 15 in-lbs (1.13 to 1.70 Nm).


591772 Rev G 77

Operation When installed in the Triple A-B Switch module, the RF Detector module can detect an RF level loss on the main input. An RF Detector module can be installed in any or all of the three internal switches.

Note: The RF Detector will not operate correctly outside of its designed operating range. RF Detector module, part number 4016545, requires an RF input level of between 30 dBmV and 60 dBmV.

When the RF Detector is installed, and its selector switch moved to the Ready/Set position, the current RF input level is read and stored in the RF Detector's nonvolatile memory. This is the current operating "set point". The Ready/Set LED turns solid green to indicate that the RF level has been stored and set.

The alarm/switching "threshold" is -6 dB from this stored "set point" input level. When the RF input level drops below threshold, an alarm is triggered and the switch automatically switches to the secondary RF input.

Important: Always check to make sure that your secondary (backup) RF source is good. There is no provision for validating the source in the backup path without routing the backup source through its own dedicated RF Detector.

Note: The RF Detector will switch back to the main RF input when the RF level goes above "set point" -3 dB for a minimum period of 10 seconds. This keeps the RF Detector from switching back and forth from main to secondary inputs due to noise.

RF Output Redundancy Example The following diagram shows an example of using Triple A-B Switches with RF Detectors to provide RF output redundancy in a GQAM application.


78 591772 Rev G

Example Summary: 1 Identical GbE sources are applied to primary and secondary (backup) GQAMs.

Both units run concurrently.


591772 Rev G 79

2 RF output #1 from the primary GQAM is applied to Triple A-B Switch #1 at its SW1 Primary connector. RF output #1 from the secondary (backup) GQAM is applied to Triple A-B Switch #1 at its SW1 Backup connector. RF outputs #2, #3, and #4 from both GQAMs are paired and connected in similar fashion to the Triple A-B Switch connectors as shown in the diagram.

3 Alarm contacts on the Triple A-B Switches are tied to the GPI ports of the ROSA EM for monitoring purposes.

4 Primary GQAM RF output signals are monitored by the RF Detectors in the Triple A-B Switches. When any of the primary RF levels drop below threshold, an alarm is triggered and the Triple A-B Switch automatically switches to the corresponding secondary (backup) RF input. The associated switch's indicator LED on the front panel of the Triple A-B Switch will illuminate red.

5 The Triple A-B Switch will automatically switch back to the primary RF input signal when the RF level goes above set point -3 dB for a minimum period of 10 seconds. The associated switch's indicator LED on the front panel of the Triple A-B Switch will revert back to green.

Important: For an application such as QAM modulator protection, the Triple A-B Switches must be configured for "independent mode" operation. In independent mode each internal switch (SW1, SW2, and SW3) operates and switches independently. To set the Triple A-B Switch to independent mode, set positions 1,2, and 3 of the internal DIP switch under the left side cover of the Triple A-B Switch to OFF.

Manual Override Operation Note: A manual override of the Triple A-B Switch can be initiated from the ROSA EM. If the RF Detector is installed in the switch the manual override function will only work from the primary to the backup input. If the RF Detector detects a fault and switches to the backup input, the manual override function cannot "override" the detector and force a switch back to the primary input.
