System LEDs

LED Color State Recommended Action
FAN 1 and 2 Off Fans are off or booting up. None
Green All fans are operating normally. None
Amber One fan has failed. Replace the failed fan. See Replacing the SSA Fan Module.
Red One or more of the following conditions has occurred:
  • Temperature is out of range.
  • The fan controller has failed.
  • Both fans have failed.
 Use the show system CLI command to check the exact condition of the fans.

If fans have failed, replace the fan module. See Replacing the SSA Fan Module.
CPU Off Power off. Ensure that the chassis has adequate power.
Amber Blinking: Device in bootup process. None
Solid: Testing. If the LED remains amber for several minutes, contact us for technical support.
Green Blinking: Image starts running. None
Solid: Functional. None
Red Solid: Processor in reset. None
Green and Amber Blinking: The SSA switch is in the process of shutting down. None. This state is activated when the RESET button is pressed for less than one second to start an orderly shutdown.
Amber and off Alternating (67% on, 33% off): A shutdown is complete. The indication holds for 60 seconds and restarts automatically. While in this state, you have 60 seconds before the SSA switch reboots.
  Blue Blinking: Virtual Switch Bonding is enabled, but the devices are not bonded None
Solid: Virtual Switch Bonding is enabled, and the devices are bonded. None
PWR Off The SSA switch is not receiving power from the power supplies. Ensure that the power cords are plugged in and that power is available at the source.

Contact us for technical support.
Green Functional. Indicates one of the following conditions:
  • A single power supply is present and operating normally.
  • Two power supplies are present and operating normally.
 None
Amber One of the following conditions has occurred:
  • Two power supplies are present but only one is operating normally while the other is not connected.
  • Two power supplies are present but only one is operating normally while the other indicates a fault.
  • Both power supplies are faulty but the SSA switch is still receiving power.
  • Power supplies are operating in additive (non-redundant) mode.
  • Other internal fault.
 Ensure that the power cords are plugged in and that power is available at the source.

Contact us for technical support.
Note

Note

The PWR LED status indication is based on power supplies being powered on.

CPU LED in Virtual Switch Bonding (VSB) Configuration describes the CPU LED when the SSA switch is in a virtual switch bonding configuration.
