G600 / CMC1
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.
