2.1.1 Status LEDs
2.1.1.1 System Status Indicators
The System Status Indicators are located just to the left of the primary power supply unit, and labeled “Sys.”.
The system status indicators should be as follows:
When the switch is plugged in, within a few seconds the STATUS LED should light up green.
The PSU 1 LED should light up green.
The PSU 2 LED should light up green only if a second PSU is installed in the switch for redundancy
and Hot-Swap ability. If only one PSU is installed in the switch, the PSU 2 LED will be off.
The FAN LED should light up green.
If the STATUS LED shows red unplug the switch and call your Mellanox representative for assistance.
If the FAN LED shows yellow, trouble shoot the fan module.
Note: Do not run the switch for more than 2 minutes should the FAN LED show yellow.
If the PSU LEDs are not green, this indicates a problem with the power supplies. Do not run the switch if the
PSU LEDs are not green.
