CSM LED Status
Combinations
PWR/ALM LED
The CSMs include on-board alarm detection. Hardware and
software/firmware alarms are indicated via the front panel indicators.
After the memory tests, the CSM loads OOS–RAM code from the Flash
EPROM, if available. If not available, the OOS–ROM code is loaded
from the Flash EPROM.
 Solid GREEN – module is INS_ACT or INS_STBY no alarm.
 Solid RED – Initial power up or module is operating in a fault (alarm)
condition.
 Slowly Flashing GREEN – OOS_ROM no alarm.
 Long RED/Short GREEN – OOS_ROM alarm.
 Rapidly Flashing GREEN – OOS_RAM no alarm or INS_ACT in
DUMB mode.
 Short RED/Short GREEN – OOS_RAM alarm.
 Long GREEN/Short RED – INS_ACT or INS_STBY alarm.
 Off – no DC power or on-board fuse is open.
 Solid YELLOW – After a reset, the CSMs begin to boot. During
SRAM test and Flash EPROM code check, the LED is yellow. (If
SRAM or Flash EPROM fail, the LED changes to a solid RED and
the CSM attempts to reboot.)
