Allied Telesis Hot swappable fan module AT-MCF2KFAN Fascicule

The fan module has one LED labeled STATUS. The states of the LED are 
defined in this table.

If the chassis is powered on but the fans in the AT-MCF2KFAN module are 
not operating, either the fan module is not receiving power or the module has 
failed. Try the following:

❑ Verify that the module is fully seated in the power supply/fan slot in the 

chassis.

❑ Verify that the power cord to the power supply module in the chassis is 

firmly connected to the power supply module and the power source.

❑ View the STATUS LED on the fan module. If the LED is amber, a fan has 

failed and stopped. Replace the module.

❑ Try removing and reinstalling the fan module.
❑ Try replacing the fan module with either another fan module or a power 

supply module. If the replacement module works, the problem is with the 
original fan module. If the replacement module does not work, the problem 
is with the chassis.
