RF Switch Card
The RF Switch provides RF data path redundancy at both the line card (slot) level and the RF port level
for bi-directional DOCSIS traffic upto 1.2 GHz. Additionally, the RF Switch cards are the coaxial cable
termination point for the Cisco RFGW-10.
Functionally the RF Switch card physically switches out a failed line card (port by port) at the RF data
path level. The card is capable of supporting (two) simultaneous RF line card failures. It is designed to
support dual N+1 redundancy groups (where N is a group of RF line cards associated with a single
"protect" card).
There are 12 RF Switch cards per chassis providing 120 RF ports for the system (Note: the chassis
MUST include all 12 RF Switch cards for proper operation). Each Switch Card supports a single Cisco
UCH2 connector header; the UCH2 supports 10 MCX coaxial connections per card. The RF Switch card
is physically separate from the RF line cards slots allowing insertion or removal of the RF line cards
without disruption of the cable plant wiring.
The RF Switch Card is the central hardware component for chassis-level HA features. The card can be
configured and controlled via the system level CLI functionality. The RF Switch card is a hardware and
firmware based module (no operating software) that can be field upgraded via the chassis CLI.
The RF Switch Card faceplate includes a single LED, which provides very high level status for power
and functionality. The LED does not indicate a line card failover.
