2 FAIL The PR-MAINT (Maintenance/Tape Processor), DUPINT
(Duplication Interface) circuit pack, or the EPN MAINT
(Maintenance) circuit pack has reported a temperature
problem because the S1 sensor has detected a
temperature of at least 65
0
C (149
0
F). The entire
cabinet is in danger of being powered down if the
temperature reaches 70
0
C (158
0
F).
1. If none of the fans are running:
a. Look for and resolve all alarms against the
CARR-POW (Carrier Port Power Unit).
b. Verify that 48 volt DC is available to the fan units.
Check the fan unit wiring harness connector.
Verify that there is 48 volt DC between pins (3, 9,
11 and 2, 8, 10).
■ If there is 48 volt DC at the connector, there
should be power to the fans. If the fans are not
running, replace the AHD1. If the fans still do not
run, follow normal escalation procedures.
■ If there is not 48 volt DC at the connector, the
current limiter card (982LS) is probably defective.
Replace the current limiter card. If the fans still do
not run, escalate the problem.
2. If only a few of the fans are not running, replace the
defective fans.
3. If all the fans can be started, wait five minutes, and
rerun the test.If the test fails again, proceed to Step
