AT-MCF2KFAN and AT-MCF2300FAN Modules

Problem 1: The STATUS LED on the AT-MCF2KFAN Module is off.

Solution: The fan module is not receiving power or has failed. Try the

following:

❒ Verify that the module is fully seated in the power supply slot in the

chassis.

❒ Replace the fan module with another fan module or with the

AT-MCF2000AC Power Supply Module.

Problem 2: The STATUS LED on the AT-MCF2KFAN Module is amber.

Solution: A fan in the module has failed. Replace the module.

Problem 3: The three FAN LEDs on the AT-MCF2300FAN Module are off.

Solution: The fan module is not receiving power or has failed. Try the

following:

❒ Verify that the module is fully seated in the slot in the chassis.

❒ Replace the module.

Problem 4: One of the FAN LEDs on the AT-MCF2300FAN Module is

amber.

Solution: The fan has failed. As a temporary measure while waiting for

the replacement module, cover the broken fan with the fan cover mounted

on the back panel of the AT-MCF2300 Chassis, as shown in Figure 84 on

page 152. The effectiveness of the remaining fans in maintaining proper

air flow and cooling in the chassis is increased if the broken fan is covered.
