LED Status

Indicated Condition

Green

On steadily

DC input voltage is present, and both main 12 V output and standby 3.3 V output are enabled and healthy.

Blinking

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.

Red

On steadily

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

Blinking

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
