6. At this point, there should be nothing impeding the
air flow, and the fans should be running at high
speed. Check the temperatures for the 15

criteria.
a. If the 15
0
C/50
0
C criteria exists, a temperature
problem exists, and the fans (at high speed)
should cool down the switch. Wait five minutes
and rerun the test. If the test still fails, the ambient
room temperature is probably too high, and the
room should be cooled.
b. If the 15
0
C/50
0
C criteria does not exist, the
AHD1 circuit pack, the fans, or the S3 or S4
sensors are defective. Replace these items one
at a time (in the order listed). Rerun the test
between each replacement. Failures can occur
on the Maintenance/Tape Processor, the
Duplication Interface, and the EPN Maintenance
circuit pack that are not detected by the
respective maintenance, but that cause many, if
not all, environment tests to fail. If many
environment tests are failing, the suspect circuit
pack, depending on the system configuration,
should be replaced and the test rerun. If this does
not clear the problem, follow normal escalation
procedures.
