Figure 9 – uBR10012 with MC28C Cards

This sample layout is the Cisco reference design shown from the rear view. If a power supply is needed

to convert AC to –48 Vdc for the 10K, it is usually on the bottom. No gaps are required between the

devices, because all air-flow is front-to-back and NEBS compliant.

Figure 10 – Sample Layout

Protect interface 5/1/0 is protecting 8/1/0 and 5/1/1 is protecting 8/1/1. Using Slot 5/1 for Protect is easier

for wiring since the Protect header of the RF Switch is located in the center.

Tip: If some US ports are combined for a dense-mode combining scenario, they could be combined at the

CMTS to free up some US ports on the RF Switch. This means, instead of taking one reverse and

splitting to feed 2 US ports before the Switch, do it after the Switch and before the CMTS.
