Thermal Alarm
Table 27 provides thermal alarm faults and the recommended actions.
Troubleshooting 5U Chassis
Table 28 describes common problems that can occur with your storage system, together with
possible solutions. For all of the problems listed in Table 28 , the Module Fault LED on the Ops panel
will light amber to indicate a fault. See 5U Chassis Ops Panel LEDs on page 128. All alarms will also
report via SES.
For information about replacing modules, see
5U84 Chassis CRU Replacement on page 190.
Table 27 Thermal Alarm Faults
Symptom Cause Recommended Action
1 Ops panel Module Fault
LED is amber.
2 Fan Fail LED is illuminated
on one or more PSUs.
Internal temperature exceeds
a preset threshold for the
chassis.
1 Verify that the local ambient environment
temperature is within the acceptable
range. See also QXS 2U/5U Environmental
Requirements on page 217.
2 Check the installation for any airflow
restrictions at either the front or back of
the chassis. A minimum gap of 25 mm (1")
at the front and 50 mm (2") at the rear is
recommended.
3 Check for restrictions due to dust build-up.
Clean as appropriate.
4 Check for excessive re-circulation of heated
air from rear to front. Use of the chassis in
a fully enclosed rack is not recommended.
5 If possible, shut down the chassis and
investigate the problem before continuing.
