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 display 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 redun-
dancy 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 assis-
tance.
If the FAN LED shows yellow, troubleshoot the fan module.
Note: Do not run the switch for more than 2 minutes should the FAN LED show yellow.
