4. Check the temperature at the top of the cabinet. If
the temperature is at least 650 C (1490 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 650 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, retu rn to St ep
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 mea sured
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.
