8692omSF module 69
You can install a 8692omSF module in both slots 5 and 6 of the 8006, 8010,
or 8010co chassis to enable redundant operation. The redundant module in
slot 6 can then assume the processing duties of a failing primary 8692omSF
module in slot 5.
When the 8692omSF module in slot 6 completes initialization, it recalculates
the topology information (Layer 2 including spanning tree groups (STG),
Layer 3 including routing topology using Routing Information Proctocol/Open
Shortest Path First (RIP/OSPF) or Border Gateway Protocol (BGP)) for
the switch unless High Availability mode (HA-CPU flag) is enabled. In
High Availability mode, all Layer 2 information is synchronized to the
redundant CPU, which results in no interruption of network services. For
more information about High Availability mode, see
Managing Platform
Operations (315545-E).
The two 8692omSF modules share switch fabric functions for the switch. If
one 8692omSF module fails, the system reverts to operation with a single
8692omSF module.

8692omSF module LEDs
The Switch LEDs and the CPU LEDs serve as a bar graph to indicate card
activity. The Switch bar graph increases as the switch fabric utilization
increases. The CPU bar graph increases when the CPU is actively
performing tasks, such as learning media access control (MAC) addresses,
updating routing tables, or interacting with the device management station.
"8692omSF module LEDs" (page 70) describes the 8692omSF module
LEDs.
