BTS Data Cable Connection

Procedure

Once the Data Cable has been built, follow the procedure in Table 4-11

to connect the BTS Data cable to the cCLPA.

Table 4-11: Procedure to Attach BTS Data Cable to cCLPA

Step Action

1 If not already performed, remove 8 screws securing I/O Panel cover.

2 Route BTS Data cable to the cCLPA. See Figure 4-12.

3 Mate Data cable RJ45 plug to I/O Board RJ45 socket. See Figure 4-12. Table 4-10 identifies the data

cable wiring.

4 If there are two cCLPAs in use, bundle cables together and place ferrite core around cables. Ensure

that the cables are not being pinched before closing and latching the ferrite core.

5 Slide ferrite core as close to the BTS connectors as possible without causing stress. Use a tie–wrap on

the ferrite core side away from the connector. The tie–wrap holds the ferrite core in place

6 Install I/O Panel Cover and secure using 8 screws. Torque screws to 2.3 N–M (20 in–lbs).
