Chapter 2 Installation Preparation

Construction Check

Before indoor cabinet installation, check the equipment room con-struction and indoor environment.

Equipment Room Construction Check

Check that the equipment room construction meets the followingrequirements:

The civil work is complete and the indoor walls are dry.

The equipment room is large enough for holding all cabinets.The door of the equipment room is greater than 2.2 m in heightand 1 m in width. The space at both the front and back of thedoor is more than 1 m. The room height is not less than 3 m.

The load bearing capacity for the equipment floor is more than450 kg/m2. The bearing capacity for the non-equipment flooris at least 300 kg/m2.

The equipment room can be installed with the antistatic activefloor. The floor is installed firmly with the horizontal inaccuracyper square meter less than 2 mm. The grounding and antistaticmeasures of the floor meets the requirements.

Air conditioners are used to keep normal temperature and hu-midity.

No drain pipe passes through the equipment room. The re-served hidden ducts and holes meet the cabling requirements.The hole size is 400 mm 400 mm. Ducts and troughs shouldbe damp-proof.

Lighting wires and power cables are grounded and hidden.Dust-proof measures are taken to protect walls and roof.

The anti-shock level reaches seven.

The lightning-arrester or rod are mounted to avoid lightningstrike. All the metal pipes are grounded at the entrance of theequipment room.

Equipment Room Indoor Environment Check

Check that the equipment room indoor environment meets thefollowing requirements:

Operating ambient temperature: -5 to +45

Relative humidity: 10%90%

The temperature and humidity are measured 2 m above thefloor and 0.4 m at the front of the equipment when the equip-ment is in operation.

Cleanness

Cleanness concerns the dust and harmful gases in the air. Theequipment should be installed in the equipment room wheremeets the following cleanness requirements:



There is no explosive, conductive, magnetic, or corrosivedust.

The density of the dust with a diameter over 5 m shouldbe no more than 3 104 particles/m3.

There is no corrosive metal or insulation-destructive gas,such as SO2 or NH3.

The equipment room should be always kept clean, withdoors and windows tightly sealed.

Power Supply Check

Check that the power supply meets the following requirements:

The equipment room is equipped with 220 V AC power supplyand both two-pin and three-pin sockets are used.

-48 V DC power is provided with the allowed fluctuation rangefrom -57 V DC to -38 V DC. The DC power supply providespower-OFF protection measures and the storage batteries areavailable for backup.

The cabling routes, quantity, and cabling position of the DCpower cables is compliant with the general regulations oftelecommunication projects. The specifications of the lineconductors applied, the dielectric strength, and the fusecapacity meet the design requirements.

The power cable employed is one-piece cable without anyjoints.

The voltage fluctuation of the mains supply does not exceed20 V, with the frequency fluctuation no more than 5%, andthe distortion rate of the cable voltage less than 5%.

The cabling of the power supply system is exact, tidy with goodinsulation, and reasonable layout.

Note:

If the system has the active/standby power supply, both the powercables should be connected in correct directions. Once the cable isconnected in a reverse direction, it may cause serious short circuit.

The power cables should be clearly separated from the signal linesand subscriber lines. In the process of laying out the power cables,make sure that the feed cables and busbar meet the medium-termor long-term expansion demands.

Grounding Cable Check

Check that the grounding cables meet the following requirements:



The cabinet has the protection grounding busbar. All the pro-tection grounding and working cables are connected to thegrounding busbar. Therefore, the protection grounding busbaris a hybrid busbar for both protection grounding and workinggrounding.

The soil type has the greatest effect on the grounding resis-tance. In an area with poor soil condition, it is recommendedto add the resistance reducer (like acrylamide) around thegrounding stub.

Temperature also affects the grounding resistance. In northernChina, it is recommended to embed stubs deep to reduce thetemperature effect. The grounding stub is made of galvanizedmaterial.

Use electricity-conductive cables with cooper jacket to connectthe grounding stub and equipment. Their cross section areasis not less than 50 mm2 and the distance should be as shortas possible. If necessary, take corrosive-proof measures forgrounding connectors to lower the resistance.

Safety Check

Check that the equipment room meets the following safety re-quirements:

Shelf InstallationThe shelf is packed together with the cabinet. Therefore, it is onlynecessary to check whether the screws of the fixed shelves aretight and whether the connection lines are loosened.



In case of expansion, the shelf is packed separately and needs tobe installed.

On the two sides of the cabinet front, there are two columns forinstallation positioning. In actual installation, place the shelf hor-izontally on its bracket and push it into the cabinet. Tighten theM5 14 screw with the floating nut on the column to ensure thefirmness of all the shelves. The shelf can be fixed by four panelscrews, and can be flexibly placed in the cabinet as required.

Figure 65 shows the shelf installation.

Card InstallationPreparation Before installing a circuit board, do as follows:

Remove sundries from the cabinet and the frame.

Take out the circuit card from the antistatic bag and removethe moisture-proof bag.

Check whether the circuit card name is the same as that onthe packing list and whether the parts on the circuit card aredamaged or fall off.

Card Installation Each shelf is installed with a floating grounding reed, so all thecards use the same grounding cable in the shelf.

To install a card, perform the following steps:

1. Insert the card according to the slot name on the upper andlower beams of each shelf.

2. Press claspers on the card and push it in until it is latched,which means the card is in place.



Caution:

While installing a card, wear antistatic wrist straps.
