Redundant Power Supply/Cooling Fan Modules Required

What Caused the Problem?

Your RAID enclosure requires redundant power-fan modules, but only one power-fan module is present. A fan module is in the place of one of the power-fan modules. The Recovery Guru Details area provides specific information you will need as you follow the Recovery Steps.

Caution: Possible loss of data accessibility. Do not remove a component when either (1) the Service action (removal) allowed (SAA) field in the Details area of this recovery procedure is NO, or (2) the SAA LED on the affected component is OFF (note that some products do not have SAA LEDs). Removing a component while its SAA LED is OFF may result in temporary loss of access to your data. Refer to the following Important Notes for more detail.

Caution: Electrostatic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touching components without using a proper ground may damage the equipment.

Important Notes

The storage array currently does not have redundant power-fan modules. A power-fan module contains a power supply and cooling fans. The storage array will continue to operate with the remaining power-fan module; however, failure of the remaining power-fan module will result in a loss of access to the storage array. Therefore, make sure you correct this problem as soon as possible.
Service Action Allowed Important Information:
- The Service Action (Removal) Allowed field in the Details area indicates whether or not you can safely remove the component. If the SAA field is NO, then the affected component must remain in place until you service another component first.
- The Service Action LED on Component field in the Details area indicates whether or not a physical SAA LED is present on the hardware component. This field does NOT indicate whether the LED is ON or OFF (that indication is provided by the Service Action (Removal) Allowed field).
- If a component does not have an SAA LED, then it is OK to remove the component when its fault LED is lit and the Service Action (Removal) Allowed status = YES in the Details area.
- The Service Action (Removal) Allowed field shown in the Details area and the physical SAA LED on the hardware component (if supported) MUST match before you remove the affected component. In rare cases (such as multiple problems), the status of the LED and the SAA field may not match. If there is a mismatch, then you should NOT remove the component until these indications match.

Recovery Steps

1	Check the Details area for the location of the fan module, then remove the fan module.
2	Insert a new power-fan module securely into place. Ensure that the power cord is correctly attached and turn on the power.
3	Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your technical support representative.
