SSC Redundancy LED States

SSC Redundancy LED States
The Redundancy LED on the SSC indicates that software is loaded on the card, but it is serving as a standby
component. SSC support 1:1 redundancy; the Redundancy LED should be green on the other SSC for normal
system operation.
The possible states for this LED are described in the following table. If the LED is not green, use the
troubleshooting information in the table to diagnose the problem.

SSC System Status LED States

The System Status LED on the SSC indicates the that there is a loss of service somewhere in the system. If
this LED is red, the system requires maintenance or service (for example, the system could not locate a a valid
software image at boot-up, or a high temperature condition exists).
The possible states for this LED are described in the following table. If the LED is not green, use the
