FAIL 

(Cont)

 / 

In a G600 or CMC1, this error code indicates a failure in either:

●

Power supply

●

Fan Assembly

There is a fan, temperature, power, or voltage problem in one or more of the 
cabinets.  The power supply’s LEDs may indicate the problem’s source. 

1. If none of the fans are running, then:

a. Verify 8- to 14-Volt DC power is available to the fan units by checking 

the wiring connector. If there is 8- to 14-Volt DC power at the 
connector, there should be power to the fans. If the fans still do not 
run, replace the fan assembly.

b. If not, then the power unit’s fan output is defective or thermally shut 

down.  Let the power unit cool, and recycle AC input power.  If no fan 
output, replace the power unit.  If the fans still do not run, escalate 
the problem.

2. If only 1 of the fans is not running, replace the fan.

3. If every fan can be started, wait 5 minutes and rerun the test. If the test 

fails again, proceed to Step 4 or 5 as applicable.

4. If the fans are not at high speed, measure the cabinet’s temperature at 

the air intake and the air exhaust at the top of the cabinet.

a. If the 5- to

 

60

0

-C criteria is met, there is a problem with the fans that 

is preventing the fans from operating at high speed. Replace the 
fans. If the fans run at high speed, wait 5 minutes to give the cabinet 
time to cool down and, rerun the test. If the problem persists, go to 
step 5.

b. If not, the Processor circuit pack is incorrectly reporting this 

condition. Look for and resolve every error on these MOs first, then 
rerun the test.
