temperature at the air intake and the air exhaust at the
top of the cabinet.
a. If the 15
0
C/50
0
C criteria is met, there is a problem
with either the AHD1 circuit pack or the fans that is
preventing the fans from operating at high speed.
Replace the AHD1 circuit pack and/or the fans. If this
succeeds in getting the fans to run at high speed, wait
five minutes to give the cabinet time to cool down and,
rerun the test. If the problem persists, go to step 5.
b. If the 15
0
C/50
0
C criteria is not met, the PR-MAINT
(Maintenance/Tape Processor), DUPINT (Duplication
Interface) circuit pack, or the EPN MAINT
(Maintenance) circuit pack is incorrectly reporting this
condition. Look for and resolve all errors on these
maintenance objects first, then rerun the test. If the
test still fails, escalate the problem.
5. If the fans are running at the high speed, check the items
on list that follows. Any on of the items could be
restricting or redirecting the flow of air within the cabinet.
a. Check both filters. If a filter is dirty or clogged it should
be cleaned or replaced. The filters 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 door is properly closed. The
door 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.
