1 System error LED (amber)
An error has been detected on the server. Causes might include one or more of the following errors:

  • The temperature of the server reached the non-critical temperature threshold.

  • The voltage of the server reached the non-critical voltage threshold.

  • A fan has been detected to be running at low speed.

  • The power supply has a critical error.

  • The power supply is not connected to the power.

Complete the following steps:

  • Check system logs or internal error LEDs to identify the failed part.

2 System power LED (green)The states of the system power LED are as follows:

  • Off: No power supply is properly installed, or the LED itself has failed.

  • Flashing rapidly (four times per second): The server is turned off and is not ready to be turned on. The power-control button is disabled. This will last approximately 5 to 10 seconds.

  • Flashing slowly (once per second): The server is turned off and is ready to be turned on. Press the power-control button to turn on the server.

  • On: The server is turned on.
