STS Amber OFF Indicates no health or environmental problems.
See Note beneath table.
RDY Green Flashing 1x / sec Indicates normal processor activity.
Note
Normal behavior for the FC blade PWR, STS, and RDY LEDs is not the same as normal
behavior for the utility module PWR, STS, and RDY LEDs.
During initialization, the FC blade’s amber STS LED remains ON until the firmware
enters its main scheduling loop.
If initialization fails, the FC blade’s amber STS LED remains lit and the blue PWR LED
blinks, a numeric fault code displays. Table 15
lists the numeric fault codes. If
initialization succeeds, the amber STS LED goes OFF, the green RDY LED blinks
once per second, and the blue PWR LED blinks once every 10 seconds.
