Safety Information

NOTE

This document aims to provide simple and distinctive guidelines for hardware installation.This document does not describe operations for the pre-delivery installation. Instead, this documentdescribers only the operations for on-site installation.

Bundling cables

The distance between cable ties or fiber binding straps inside the cabinet should be within 250 mm. (Forsubscriber cable, the distance is 200mm. )

The distance between cable ties for all cables and corrugated pipes outside the cabinet is determinedaccording to the distance between two horizontal beams. For the cabling trough without beams, bundle thecables with the distance not exceeding 250 mm between cable ties.

Electrostatic Discharge

Before touching the device, or holding the boards and IC chips, wear the anti-static wrist strap to preventthe electrostatic discharge of the human body from damaging the sensitive components. Ensure that theother end of the anti-static wrist strap is well grounded.

Checking Before Installation

Before starting installation, you should make the equipment room, power supply, ground wire, opticalcables, and other facilities in the equipment ready. When these installation conditions are confirmed, theinstallation may begin according to the pre-designed layouts.For detailed requirements and related index,refer to Installation Reference.

Optional: Replacing the CF Card

2 Installing the CF Card

Remove the CXPAR/CXPBR/CXPGR/CXPHR board and thenremove the CF card on the board.

Install a new CF card onto the CXPAR/CXPBR/CXPGR/CXPHR board. When installing the CFcard is complete, insert the CXPAR/CXPBRCXPGR/CXPHR board.

Make sure that the pins and CFcard are correctly aligned.

When installing or removing the CF card, wear an ESD-preventive wrist strap or ESD-preventive gloves, and apply proper force to prevent that the pins for the CF card bend.

When installing the chassis on the wall, there should be no other objects, including cables, within 300 mm inthe front of the equipment face, or within 100 mm below the bottom or above the top.When routing power cables, make sure that the power cables are far from the E1 cable, fiber, and networkcable.

Procedure of Installing Fibers and Cables (in the Scenario Where the Chassis Is Installedin a Cabinet or on the Wall) :

Certain operations are optional. Before performing an optional operation, consult with the engineeringsupervisor or software debugging engineer to decide whether to perform the operation. The otheroperations are mandatory.

The following table defines the EXT/F1 interfaces on the CXPAR.

Install and route IF jumpers.When deploying the IF jumper in the cabinet, you should deploy it far from the E1 and network cables todecrease the interference between transmission signals.When installing and routing IF jumpers are complete, connect the IF jumpers to the outdoors IF cables tofinish the installation.

Install and route fibers.The bend radius of the fiber must be greater than its minimum curvature radius. Specifically, the minimumcurvature radius for the 2 mm fiber jumper is 40 mm.

Checking the Installation

The connecting points of the fiber jumpers should be free of dust. The unused fiber connectors and optical

interfaces should be protected by protective caps (plugs).

18

The fiber jumpers should not be bound over-tightly, and can be moved freely in the cable tie.17

The cuts of the protective tube for the fiber jumpers should be smooth. Otherwise, they should be

wrapped by an insulating tape.

16

The protective tube for the fiber jumpers should be led into the cabinet and bound tightly.15

The unused cable connectors should be protected. For example, the connectors should be installed with

protective caps.

14

The power cable and grounding cable should be routed separately from the signal cables.13

The cable labels should be filled in correctly and stuck reliably. They should be aligned and face to the

same direction. The labels need to be stuck two centimeters away from the connectors.

12

The cable turns should be smooth and have a big bending radius.11

The cables outside the cabinet should be routed as follows:

The cables should be placed tidily and be free of crossover.

In the case of a cabling ladder, the cables should be bound onto the ladder beam tidily. If the cabling

frame is 0.8 m or more higher than the cabinet top, a cabling ladder should be available on the cabinet top

to support the cables and to ease stress.

10

The signal cables should be routed correctly in the cabinet.9

The cables should be bundled closely with proper force. The spacing between the cable ties should be

even. After the cable ties are fixed, the remaining part should be trimmed with no burrs.

8

Each core of the cables should be tested for connectivity.7

The cables should be free of damage, break, or joint in between.6

The routing of the cables should conform to the engineering design document and should facilitate

maintenance and expansion in the future.

5

Empty slots in the chassis should be covered with filler panels.4

When a board is inserted into the chassis, the screws on the front panel of the board should be tightened.3

Each chassis component should be free of paint drop, damage, or stain. Otherwise, re-paint or clean the

component.

2

The chassis should be installed firmly in the position specified in the engineering design document.1
