2FAIL
(cont’d.)
4. Check the temperature at the top of the cabinet. If the
temperature is at least 65
0
C (149
0
F), the ambient room
temperature is too high, and the fans cannot cool the
system. Unless the room temperature is reduced, the
system is going to shut down soon. If the temperature is
less than 65
0
C, then:
5. The PR-MAINT (Maintenance/Tape Processor), DUPINT
(Duplication Interface) circuit pack, or the EPN MAINT
(Maintenance) circuit pack may be incorrectly reporting
this condition.
a. First, look for and resolve all errors on these MOs,
then rerun the test.
b. If this test fails again, go to Step 6.
6. The sensor S1 may be incorrectly reporting the
temperature at the top of the cabinet. Replace sensor S1,
and rerun the test. If the test still fails, escalate the
problem.
3 FAIL The AHD1 circuit pack has reported both air flow and
temperature problems. Resolve the airflow error first, then,
correct the temperature error as described previously.
PASS The AHD1 circuit pack has not reported any temperature or
air flow problems. The temperatures at the air exhaust at the
top of the cabinet and the air intake at the bottom of the
cabinet can be measured and the results compared against
the criteria described previously. If a problem has been
reported, troubleshoot this problem by using the procedures
for the “FAIL” cases described previously.
