Description and recommendation
5. If the fans are running at high speed, check the following items. Any
one of these could be restricting or redirecting the cabinet’s air flow:
a. Check the filter. If the filter is dirty or clogged, it should be
cleaned or replaced. The filter can either be washed with soap
and water or vacuumed.
b. Verify that nothing other than circuit packs are in the carrier
slots that could be restricting air flow.
c. Verify that no circuit-pack blanks or carrier faceplates are
missing. Install and/or replace them as necessary.
d. Be sure the cabinet’s doors are properly closed. The doors
must be closed to enable the fans to properly cool the cabinet.
Wait 5 minutes to allow the fans to cool the cabinet. Rerun the
test. If the test still fails, proceed to Step 6.
6. At this point, there should be nothing impeding the air flow, and the
fans should be running at high speed. Check the temperatures for
the 5- to 600-C criteria.
a. If the 5- to 60 0 -C criteria exists, a temperature problem exists,
and the fans (at high speed) should cool down the switch. Wait
5 minutes, then rerun the test. If the test still fails, the ambient
room temperature is probably too high, and the room should be
cooled.
b. If the 5- to 600-C criteria does not exist, the fans are defective.
Replace the fan assembly and rerun the test. Failures can
occur on the Processor circuit pack that are not detected but
that cause many, if not every, environment test to fail. If many
environment tests are failing, the suspected circuit pack,
depending on the system configuration, should be replaced and
the test rerun.
7. There is a problem with the environment of the power system. The
power unit for the cabinet may be defective.
a. Verify and, if necessary, replace the power unit.
b. Rerun the test. If the test still fails, escalate.
PASS This indicates that the power/fan lead is off and there are no failures in the
G650 or G650 stack.
