Front Panel LEDs

LED Icon Light Description
Power

Fault
(amber)
On (Not Flashing)

Indicates a problem that is not fatal to the server but that you should attend to as soon as possible. Circumstances that cause the Fault LED to light up include the following:

  • The temperature inside the server's enclosure is unusually high.
  • The voltage on one of the server's output supply is unusually high.
  • One of the server's internal circuit breakers has tripped, indicating a problem with a device connected to the SCSI or USB ports.
  • The System Configuration Card, containing the server's serial number, MAC address and NVRAM settings, has been removed.
  • One of the DC power inlets has failed.
  • The LOMlite2 watchdog has timed out, indicating that the server has locked up. You can configure the server to restart automatically after a lockup.

 

Flashing On and Off

A problem has occurred that is fatal to the server. Circumstances that cause the Fault LED to flash include the following:

  • The speed of one of the fans inside the server is too low.
  • The temperature inside the server's enclosure is too high. (By default, this causes the server to shut down.)
  • The voltage on one of the server's output supply rails is to high. (By default, this causes the server to shut down.)
  • The temperature inside the CPU is too high. (This causes the server to shut down.)
