• when the gateway is plugged in, within five minutes the gateway status LED should
light up green
• the FAN LED should light up green. If the FAN LED shows red,troubleshoot the fan
module. See page 57.
• 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 gateway for redundancy 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 gateway, the PS2 LED will be off
If the PS LEDs are not green, this indicates a problem with the power supplies. The gateway is
operational only if at least one of the PS LEDs is green.

Gateway Status LED
Figure 6: Gateway Status LED
As long as there is power to the gateway (one PS unit is connected), and the gateway
is booted up and running, the gateway status LED should be green.
If the status LED shows red after five minutes, unplug the gateway and call your Mel-
lanox representative for assistance.
If the gateway shuts down due to over temperature, unplug the gateway, wait 5 min-
utes and replug in the gateway. For more information See page 57.
