LEDs OK/FAIL LED, one bicolor:
• Steady green–The SPC is operang normally.
• Red–The SPC has failed and is not operang normally.
• O–The SPC is powered down.
STATUS LED, one tricolor for each of the four SPUs SPU 0 through SPU 3:
• Green–The SPU is operang normally.
•
Amber–The SPU is inializing.
•
Red–The SPU has encountered an error or a failure.
•
O–The SPU is oine. If all four SPUs are oine, it is safe to remove the SPC from the
chassis.
SERVICE LED, one bicolor for each of the four SPUs SPU 0 through SPU 3:
• Green–Service is running on the SPU under acceptable load.
• Amber–Service on the SPU is overloaded.
• O–Service is not running on the SPU.
HA LED, one tricolor:
• Green–Clustering is operang normally. All cluster members and monitored links are
available, and no error condions are detected.
• Red–A crical alarm is present on clustering. A cluster member is missing or unreachable,
or the other node is no longer part of a cluster because it has been disabled by the dual
membership and detecon recovery process in reacon to a control-link or fabric-link
failure.
• Amber–All cluster members are present, but an error condion has compromised the
performance and resiliency of the cluster. The reduced bandwidth could cause packets to
be dropped or could result in reduced resiliency because a single point of failure might
exist. The error condion might be caused by:
• The loss of chassis cluster links which causes an interface monitoring failure.
• An error in an SPU or NPU.
• Failure of the spu-monitoring or cold-sync-monitoring processes.
