ond PSU LED will be off.
The FAN LED should light up green.
If the FAN LED shows red, troubleshoot the fan module.
If the PSU LEDs are not green, this indicates a problem with the power supplies. Only run the
switch if at least one of the PSU LEDs is green.

As long as there is power to the switch (one PSU is connected), and the switch is
booted up and running, the status LED will be green.
If the STATUS LED shows red after five minutes unplug the switch and call your Mel-
lanox representative for assistance.
If the switch shuts down due to over temperature, unplug the switch, wait 5 minutes
and replug in the switch. For more information See “Troubleshooting” on page 49.
