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_SBY 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_SBY 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.)
