7.19.3 Voltage and Temperature Errors and Warnings

Most voltage and temperature errors and warnings relate to the Power Supply/Cooling modules. Check the following to resolve these errors or warnings:

1Check that all of the fans are working by making sure all of the Galaxy 65 Subsystem’s LEDs are green or using the SAM status pages.

2Make sure that all the Galaxy 65 Subsystem modules are properly seated in their slots and that their handles are locked.

3Make 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 cover to close the slot. Leaving a slot open negatively affects the airflow and may cause the unit to overheat.

4Try replacing each Power Supply/Cooling module, one at a time.

5Replace the SM modules, one at a time.

7.20 Slow Write Performance

This can be caused by powering down the enclosure without first shutting down the controllers.

• The battery must be greater than 90% charged for write back cache to be enabled.
