Power/Fan Lead Query Test (#1533)
G600 / CMC1
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 Step 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 600-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.
