Chapter 4 Cabling the RF Switch With the Cisco uBR10012 CMTS Cable Interface Line Cards
Connecting the RF Cables (Cisco uBR10-MC5X20S/U/H)
Cabling the Output Cables (CABLE PLANT to HUB)
This section describes cabling the RF switch for output.
CABLE PLANT cable headers are wired in the reverse sequence of the CMTS and PROTECT headers
(see Figure 4-17 on page 4-30). Use the same connection methods as described in:
• “Mapping the Working and Protect Cisco uBR10-MC5X20S/U/H Line Cards RF Cables to the RF
Switch” section on page 4-21
• “Connecting the RF Cables (Cisco uBR10-MC5X20S/U/H)” section on page 4-26
Note CABLE PLANT slots on the Cisco uBR 3x10 RF Switch are numbered in reverse sequence from CMTS
and PROTECT. Slot number one is on the far right. Refer to Figure 4-17 on page 4-30 for header block
and cable designations as viewed from the cable side of the header blocks.
Equipment
• 7 RF cable kit: CAB-RFSW520TPMF (RFS to cable plant, MCX to F, two 10-bundle, one 5-bundle)
• 14 header blocks provided with input cable kits
To cable the output connections, complete the following steps. See Figure 4-17 on page 4-30.
Step 1 Install the header blocks on the CABLE PLANT section of the RF switch.
Step 2 Install the output cables in the header blocks. Refer to the “Connecting the RF Cables
(Cisco uBR10-MC5X20S/U/H)” section on page 4-26 for MCX connector installation instructions.
Note The output cables (CABLE PLANT) on the Cisco uBR 3x10 RF Switches are cabled in the reverse order
of the input cables (CMTS).
Step 3 Run the output cables (H–A) from header blocks to splitters, US laser receivers, or the low side of the
diplex filters.
Step 4 Run the output cables (M, F, G) to the splitters/combiners, DS laser transmitters, or the high side of the
diplex filters.
Note N is not used.
