Indicated Condition
DC input voltage is present, and both main 12 V output and
standby 3.3 V output are enabled and healthy.
DC input voltage is present, standby 3.3 V output is on, but
the main 12 V output is disabled. This condition usually
indicates that the device has been powered off at the Power
button on the SYSIOC front panel. It may also indicate that
either the SYSIOC or Routing Engine has been removed from
the services gateway.
The power supply has detected one or more of the following
faults:
Power supply fan failure
Power supply over-temperature condition
Over-current or under-voltage condition on the standby
3.3V output
The power supply has detected one or more of the following
faults:
Under-voltage condition on the 12 V output
Over-voltage condition on the 12 V output
Over-current condition on the 12 V output
