SF/CPU modules
69
When the 8691 SF/CPU module in slot 6 completes initialization, it
relearns the routing and VLAN bridging information for the switch (unless
you enable HA-CPU). In this case, the static routes and ARP entries
for routing synchronize to the redundant SF/CPU, which results in no
interruption of network services.
The two 8691 SF/CPU modules share switch fabric functions for the
switch. If one 8691 SF/CPU module fails, the system reverts to operation
with a single 8691 SF/CPU module.
8691 SF/CPU LEDs
The following figure shows the location of the 8691 SF/CPU module LEDs.

8691 SF/CPU module LEDs
The Switch LEDs and the CPU LEDs indicate card activity. The Switch bar
graph increases as the switch fabric utilization increases. The CPU bar
graph increases when the CPU is performs tasks, such as learning media
access control (MAC) addresses, updating routing tables, or interacting
with the device management station.
The following table describes the 8691 SF/CPU module LEDs.
