2Ensure that all cables are properly connected and that there are no bent pins in the connector. If problems are encountered, see "Getting Help" on page 77.

Troubleshooting Power Supplies

Problem

•Enclosure-status indicators show a problem.

•Power-supply fault indicators are lit.

Action

CAUTION: Only trained service technicians are authorized to remove the enclosure cover and access any of the components inside the enclosure. Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the enclosure and protecting against electrostatic discharge.

1Check that at least two physical disks are present in the enclosure. A minimum of two physical disks must be installed. If they are not, install the minimum number of physical disks. If the problem persists, go to step 2.

2Turn off the enclosure and attached peripherals, and disconnect the enclosure from the electrical outlet.

3Locate the faulty power supply.

If the power supply's fault indicator is lit, see "Power Supply and Cooling Fan Features" on page 18.

NOTICE: Power supply/cooling fan modules are hot-pluggable. The enclosure can operate on a single functioning power supply; however, both modules must be installed to ensure proper cooling. A single power supply/cooling fan module can be removed from the enclosure for up to 5 minutes, provided the other module is functioning properly. After 5 minutes, the enclosure will overheat and may cause an automatic thermal shutdown.

4Ensure that the power supply is properly installed by removing and re-installing it. See "Removing and Installing the Power Supply/Cooling Fan Module" on page 62.

NOTE: After installing a power supply, allow several seconds for the enclosure to recognize the power supply and determine if it is working properly.

5If the problem is resolved, skip the rest of this procedure.

If the problem persists, remove the faulty power supply. See "Removing and Installing the Power Supply/Cooling Fan Module" on page 62.

6Install a new power supply. See "Removing and Installing the Power Supply/Cooling Fan Module" on page 62.

If the problem persists, see "Getting Help" on page 77.
