(cont’d.)
4. If the fans are not at high speed, measure the cabinet temperature at
the air intake and the air exhaust at the top of the cabinet.
a. If the 5 - 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 the 5 - 60
0
C criteria is not met, the Processor circuit pack is
incorrectly reporting this condition. Look for and resolve all errors
on these maintenance objects first, then rerun the test.
5. If the fans are running at the high speed, check the items on list that
follows. Any one of the items could be restricting or redirecting the
flow of air within the cabinet.
a. Check 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. Make sure there is nothing other than circuit packs in the carrier
slots that could be restricting the air flow.
c. Make sure there are no missing (blank) circuit pack or carrier
faceplates. Install and/or replace them as necessary.
d. Make sure the cabinet doors are properly closed. The doors must
be closed for the fans to be able to properly cool the cabinet. Wait
five minutes to give the fans a chance to cool the cabinet. Rerun
the test. If the tests still fails, proceed to Step 6.
1FAIL
(cont’d.)
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 - 60
0
C criteria.
a. If the 5 - 60
0
C criteria exists, a temperature problem exists, and
the fans (at high speed) should cool down the cabinet. Wait five
minutes and 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 - 60
0
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 is not detected by its maintenance
object, but that cause many, if not all, environment tests to fail. If
many environment tests are failing, check errors against the
Processor circuit pack.
