Troubleshooting the Cooling System
The cooling system consists of fan trays and an anti-dust mesh.A malfunctioning fan/fan tray or
dust-full anti-dust mesh can influence the ventilation through the chassis. When the system is
over heated, it will shut itself down.
When the cooling system malfunctions, take the following steps to troubleshoot:
l
Use the command
show environment
to view the chassis temperature and fan spinning
speed.
l
Check the fan LED. When the fans are running normally, the LED is solid green; when it is
orange or red, one or more fans fail, and you should replace the fan/fan tray immediately to
prevent over-heating of the system. See
Installing and Removing
the Fan Tray.
