Information on Cisco uBR10-MC5X20S/U/H Line Cards
Benefits
The Cisco uBR10-MC5X20S/U/H cable interface line cards provide the following benefits:
•
Expanded capacity of the Cisco uBR10012 universal broadband router, providing the highest port
density available in Cisco cable interface line cards.

Onboard Failure Logging
The On-Board Failure Logging (OBFL) feature enables storage and collection of critical failure
information in the nonvolatile memory of an Field Replaceable Unit (FRU), like a Route Processor (RP)
or line card. The Cisco uBR10000 series router supports OBFL on PRE4, the Cisco SIP-600 jacket card,
Cisco UBR-MC20x20V cable line card and the Cisco UBR-MC5x20H cable line card.
