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.

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).
