Chapter 4 Cabling the RF Switch With the Cisco uBR10012 CMTS Cable Interface Line Cards

Connecting the RF Cables (Cisco uBR10-MC5X20S/U/H)

For cabling locations, refer to:

•Table 4-7 on page 4-22for slot 8/0 and 8/1 working line card RF switch connections.

•Table 4-8 on page 4-23for slot 7/0 and 7/1 working line card RF switch connections.

•Table 4-9 on page 4-24for slot 6/0 and 6/1 working line card RF switch connections.

•Table 4-10 on page 4-25for slot 5/0 and 5/1 working and protect line card RF switch connections.

Step 4 Gently pull on the cables to be sure that they are firmly seated in the header blocks.

Step 5 Use a flat-blade screwdriver to tighten the captive installation screws at both the top and bottom of the header block to prevent accidental disconnections.

Caution Do not over-tighten the captive screws. We recommend that you tighten the captive screws to 5 to 7 inch-pounds (0.5647 to 0.7909 Nm).
