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:
a. The PR-MAINT (Maintenance/Tape Processor), DUPINT
(Duplication Interface) circuit pack, or the EPN MAINT
(Maintenance) circuit pack may be incorrectly reporting this
condition. First, look for and resolve all errors on these MOs, then
rerun the test. If this test fails again, return to Step 1. If there are no
errors, continue.
b. 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.
