Technical Specifications for Cable Bundling

1 Arrange the cables in a bundle closely, straight, and

neatly

2 The cables in a trough may not be bundled Arrange them

neatly They cannot cross each other They cannot overflow the trough

3 Route the signal cables separately from the power cables.

4 Bend a cable, if required, evenly and softly

5 The total thickness of the cables under a floor cannot

exceed 3/4 of the floor height.

6 The cables can cross within one meter after they exit the cabinet.

7 Do not damage the insulation layer of the cables when

bundling them.

8 Do not join cables.

Alarm Indicator Cable(1)

Keep the cables away from the heat dissipation hole in cabinet top.

A The row and column indicator control cables include a row indicator signal cable, column indicator signal cable, and row indicator cascade cable They drive the row and column

indicators on top of the cabinet.

B A row indicator signal cable and a column indicator signal cable share the same structure They have a 4PIN connector at one end and six UT soldering flakes at the other Fix the three soldering flakes on the three black cables to one side of the

three row and column indicators Fix the other three soldering flakes on the red, yellow, and green cables to the other side of the red, yellow, and green row and column indicators.

C For C841AMD (widely used in the previous

cabinets) insert the row indicator in J8 and the

column indicator in J9 in the AMD in the power

distribution box J6 and J7 are connected using the

row indicator cascade cable.

D For CB01AMD (used in the later assembled

cabinets) insert the row indicator in J6 and the

column indicator in J7 in the power distribution

box J4 and J5 are connected using the row

indicator cascade cable The row indicator cascade

cable has a 4PIN connector at either end.

Huawei Emergency Serial Port Cable

The emergency serial ports refer to the serial data

paths throughout the entire AM/CM and SPM system

They have connection with all subracks except CKM

They are applicable for status data report of PWS,

alarm data report of AMD, and data report and

equipment maintenance of other boards in emergency

cases The entire emergency serial port system

consists of the serial port cables in various lengths

and the connected communication nodes The cables

inside a cabinet have already been installed before the

delivery The cables between cabinets need be

installed on the site There are the following two

categories of serial port cables:

 Common emergency serial port communication

cable

Emergency Serial Port Cable

Common emergency serial port communication cable

1 All common emergency serial port communication

cables have a 4PIN connector at either end They connect

the nodes in AM/CM and SPM, including the CB01AMD in

the power distribution box and the backplanes of the

subracks.

2 There are two serial ports in the upper right (seen from

the back) of the backplane of each subrack that requires

emergency serial connection Connect the two ports in

parallel All of the ports can be connected with one serial

bus.

3 JT1 and JT2 are the serial ports in a backplane J12 and

J13 are the serial ports in AMD.

4 There are five types of emergency serial port

communication cable according to the length: 0.4-m cable, 0.8-cable, 1.2-m cable, 2.5-m cable and 4-m cable.

Huawei Emergency Serial Port Cable

Emergency serial port communication cable of BAM

1 An emergency serial port communication cable of

BAM connects the serial port in AMD in the BAM with

the emergency serial port in the basic cabinet.

2 An emergency serial port communication cable

has a 4PIN connector at either end Insert one end in

the serial port J12 in CB01AMD in the main control

subrack, and the other end in the serial port J12 (or

J13) in CB01AMD in the BAM.

Power and Signal Cable of Fan

The power and signal cable of fan supplies working

power for the fans and reporting the status signals of

the fans to the monitor unit It has a blue power

connector, a black power connector, and a fan signal

connector The power connectors are inserted in a

busbar The fan signal connector is inserted in J2 in

CB01AMD(or J1.7 in C841AMD) in the power

distribution box They have been inserted before the

delivery Pay attention to the power connector polarity

when changing the connectors on the site.

B The cables of an alarm box include a signal cable and a

Alarm Box

D The power cable supplies –48V power for the alarm box.

E The DIP switches S1 and S3 are used for setting the working mode The two RS232 ports P1 and P2 serve the serial

Huawei

Clock Cable

A The clock cables provide 8K and 2M reference clock

sources for the subracks.

B The clock cables are routed from the CKM subrack to

the subracks that require the reference clock sources.

C A clock cable is a four-pair twisted cable Its connectors are: 2  5PIN + 2  2  5PIN.

Network Cable Terminal

A The terminal system of AM/CM is a distributed and

hierarchical Server/Client architecture The Server side consists of the BAM Server and Switch There is a WS on the side of a Client.

B Tighten the screws on the connector of a load cable.
