DPC/UDPC Active LED States
The Active LED on the DDPC/UDPCPC indicates that the software is loaded on the card and that the card is ready for
operation. When the system first boots up, all installed DPC/UDPCs are booted into standby mode. The system must
then be configured as to which DPC/UDPCs should serve as redundant components (remain in standby mode) and
which should function as active components.

DPC/UDPC Redundancy LED States
The Redundancy LED on the DPC/UDPC indicates that software is loaded on the card, but it is serving as a standby
component. DPC/UDPCs support n:1 redundancy; the Redundancy LED should be green on only one DPC/UDPC for
normal system operation.
