Maintenance-Object Repair Procedures

8-392 Issue 1 May 2002
2 FAIL An EPN’s Maintenance circuit pack has reported a temperature problem due
to the S1 sensor detecting a temperature of at least 65
0
C (149
0
F). 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),
either the S1 sensor or an EPN’s Maintenance circuit pack is incorrectly
reporting the problem.
a. Resolve any errors against MAINT, then rerun the test.
b. If there are errors, replace the S1 sensor and retest. If the test fails,
escalate.
3 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.
