LED color shows the
switch status
The system status indicators should display as follows:
• When the switch is plugged in, within five minutes the STATUS LED should light up
green.
• The PS1 LED for the plugged in PS unit should light up green
• The PS2 LED for the second PS unit should light up green only if a second PS unit is
installed in the switch for redundancy and Hot-Swap ability and it is connected to a
power source.
• If two PS units are installed and only one PS unit is connected to a power supply the PS2
LED will be red.
• If only one PS unit is installed in the switch, the PS2 LED will be off.
• The FAN LED should light up green.
As long as there is power to the switch (one PS unit is connected), and the switch is
booted up and running, the status LED should be green.
If the STATUS LED shows red after five minutes, unplug the switch and call your
Mellanox representative for assistance.
If the FAN LED shows red, troubleshoot the fan module. See "Troubleshooting" on page 51.
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 51.
If the PS LEDs are not green, this indicates a problem with the power supplies. The switch is
operational only if at least one of the PS LEDs is green.
