HDS-B overview

1 HDS-B overviewMain functions of HDS-BThe HDS-B plug-in unit serves as a non-volatile memory for program code and data in the MGW and RNC. It connects to the OMU and integrated OMS units via the SCSI bus.

Operating environment of HDS-BThe HDS-B plug-in unit works with the OMU and integrated OMS units. The computer units have two 16-bit wide Ultra SCSI buses which connect to the HDS-B through external shielded backplane cables. The HDS-B has two independent SCSI buses for two computer units. In the case of OMU, the SCSI buses pass through the HDS-B and continue to the other unit of the duplicated pair (OMU only). In the case of integrated OMS, the SCSI buses pass into the HDS-B and end there. It is possible to connect other SCSI devices on the same bus. The maximum number of installed SCSI devices, not counting computer units, is 14.

The HDS-B plug-in unit is connected to the hardware management bus via the bus inter-face of the HMSS. HDS-B has an interface to two HMS transmission lines via back con-nectors.

The HDS-B has automatically functioning SCSI bus terminators.

The HMSS has a separate 2N redundant power feed.

The HDS-B gets also 48V DC supply and power feed from the HMSS through back con-nectors. The operational environment of HDS-B is shown in Figure 1 Operational envi-ronment of the HDS-B.

HDS-B structure

3 HDS-B structure

3.1 Mechanical structure of HDS-BThe HDS-B plug-in unit is implemented with a single standard IPA2800 full size printed wiring board (PWB). The size of the PWB is 265 mm x 287.3 mm (height x length).

The hard disk drive (HDD) is 26.1 mm high and is fastened on the PWB with screws from the bottom of the drive. The devices are located so that the connector side is towards the upper edge of the PWB. Other components are mainly surface mount components.

There are four different power voltages on the HDS-B:

HDD: +12V and +5V HMSS: +5.3V SCSI termpower: +5VThe HDD's +12V and +5V are routed by using wide traces. The HMSS and SCSI term-power split the layer 5. Layer 6 is used for the GND plane.

HDS-B HDS-B structure


The HDS-B connects to the backplane via AMP Z-pack connectors.

Internal interfacesThe HDS-B consists of four distinct hardware blocks. The hardware blocks are described in more detail in the section Logical structure of HDS-B. Interfaces between the four blocks are described below.

HDD - HMSSThere is no interface between the HDD and HMSS hardware blocks.

HDD - PowerIn the power block, DC/DC units supply +12 V and +5 V outputs to the circuit board. Both disks have four wires and a 4-pole power connector on the circuit board. This way the hard drives are supplied by their operating voltages.

HMSS - PowerThe power block generates an alarm signal to the HMSS. Both the power feed's alarm output and the HMSS's alarm input use TTL level signals and only logic level changes matter, so no adjustment is needed. The power alarm input in the HMSS is input 0 (A0).

The HMSS can shut down the HDS-B's DC/DC units. The power enable signal coming from the HMSS has an output low voltage (VOL) max 0.45 V and output high voltage (VOH) min 2.4 V. The current is sufficient so that the power enable interfaces of the HW blocks can be routed straight together.

3.3 Logical structure of the HDS-BThe HDS-B plug-in unit consists of the following hardware blocks:

Two Hard Disk Drives (HDD) HMS Slave Node (HMSS) PowerThe block diagram of the HDS-B is shown in Figure 4 Block diagram of HDS-B.

HDS-B structure

Figure 4 Block diagram of HDS-B

HDD blockThe Hard Disk Drives provide an interface to the SCSI buses. An HDD consists of a hard disk, two SCSI buses, and the SCSI bus termination.

The SCSI interfaces support the SCSI-3 Fast-20 16-bit interface at 160 MB/second syn-chronously and 5 MB/second asynchronously. The active termination method recom-mended in the SCSI-3 specificatio is used. The termination can support both termination modes SE and LVD. The termination mode depends on DIFFSENS signal which is driven by SCSI device HDD or CPU plug-in unit.

The termination works automatically. If the HDS-B is the only device in the SCSI bus, then the termination is switched on in the HDS-B. If the SCSI bus continues to another unit, the termination is switched off. Termination circuits are powered by TERMPOWER line in the SCSI bus.

g If integrated OMS is not in use, the HDD for integrated OMS will be removed from HDS-B plug-in unit.HMSS node blockThe Hardware Management System Slave node provides an interface to the Hardware Management System. HMS slave node collects alarm information and the node is also used in diagnostics.

The Hardware Management System has its own bus so it is not dependent on the ATM-based messaging. It has its own power supply, which is separate from the plug-in unit's power supply. This is because the Hardware Management System has to remain oper-ational even if normal messaging and/or power distribution fails.

Power blockThere is a power unit (DC/DC converter) integrated in the HDS-B plug-in unit. It receives -48V from the backplane connector and generates 5 V and 12 V for the hard drive.

The HMSS node has its own power supply that is independent of the plug-in unit's power supply. The plug-in unit's power supply can be turned off via the HMSS. If the voltage level of the unit power supply is too low or too high, an alarm (A0) is generated to the HMSS.

HDS-B connector maps

7 HDS-B connector mapsBackplane connectorsThe HDS-B connects to the backplane with five (modules 1 - 5) Z-pack HM connectors. The connector modules are numbered 1 to 5 from the top down. The uppermost con-nector in module 1 is unshielded 110 position type A connector with multipurpose centre. The connector in modules 2, 3 and 5 is upper shielded type B. The connector in module 4 is upper shielded connector of type A. The numbering of the connector rows is from 1 to 125 from the top down.

The SCSI buses come into the plug-in unit through the back connector and are looped back to the connector on the circuit board. The SCSI buses use connector modules 2, 3, 4 and 5. On the circuit board SCSI termination for the 16-bit SCSI bus is connected to the SCSI bus loop.
