CABINET (Cabinet Sensors)

FAIL A temperature problem due to the S1 sensor detecting a temperature of at
least 65
0
C (149
0
F) has been reported. The entire cabinet is in danger of
power-down if the temperature reaches 70
0
C (158
0
F).
1. If any of the fans are not running, there should be a FAIL with Error
Code 1 present. Follow the procedures for that Error Code, noting the
differences for variable- and constant-speed fan assemblies.
2. If the fans are running, check the temperature at the top of the cabinet.
a. 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 will shut down
soon.
3. If the temperature at the top of the cabinet is less than 65
0
C (149
0
F),
the S1 sensor, or a PN’s Maintenance circuit pack is incorrectly
reporting the problem.
a. Resolve any errors against the S1 sensor or against MAINT), then
rerun the test.
b. If there are still errors, replace the S1 sensor and retest. If the test
fails, escalate.

FAIL Fan failures and temperature alarms have been reported.
1. Resolve the fan failure (Error Code 1). This should also resolve the
temperature alarm. (With constant-speed fan assemblies, fan failures
correspond to air-flow problems.)
PASS Temperature measurements and fan performance are satisfactory.
