Protection Scheme for the Cisco uBR10012 CMTS

The N+1 redundancy protection scheme you select for your system depends largely on the number and type of cable interface line cards you have installed in your Cisco uBR10012 router. The 7+1 eight-card redundancy scheme supports redundancy among the cable interface line cards installed in a fully populated Cisco uBR10012 router. Other redundancy schemes are designed to support partial cable interface line card population in a Cisco uBR10012 router.

Note We recommend that the protect card be installed in slot 5/0 because this slot is directly below the PROTECT section on the RF switch.
