Resolving Voltage and Temperature Warnings
1. Check that all of the fans are working by making sure each power-and-cooling
module’s DC Voltage/Fan Fault/Service Required LED is off or by using SMU to
check the Status Summary page (select Monitor > Status > Status Summary).
2. Make sure that all modules are fully seated in their slots and that their latches are
locked.
3. Make sure that no slots are left open for more than two minutes.
If you need to replace a module, leave the old module in place until you have the
replacement or use a blank module to fill the slot. Leaving a slot open negatively
affects the airflow and can cause the enclosure to overheat.
4. Try replacing each power-and-cooling module one at a time.
5. Replace the controller modules, one at a time.
Sensor Locations
The storage system monitors conditions at different points within each enclosure to
alert you to problems. Power, cooling fan, temperature, and voltage sensors are
located at key points in the enclosure. In each controller module and expansion
module, the enclosure management processor (EMP) monitors the status of these
sensors to perform SCSI enclosure services (SES) functions. Various SMU pages
display the sensor information, for example Monitor > Status > Module Status.
The following sections describe each element and its sensors.
