Replacing a fan module The variable-speed fan module is hot-pluggable, so it is not necessary to power down the system to replace it. Before you begin CAUTION: • Before removing a component or blanking panel from an operational device, make sure that you have the replacement part available. Removing a component or blank impacts the airflow and cooling ability of the device. To avoid possible overheating, insert the new or replacement component within one or two minutes. If the internal temperature exceeds acceptable limits, the device may overheat and automatically shut down or restart. • Parts can be damaged by electrostatic discharge. Use proper anti-static protection. CAUTION: • Replacement power supply assemblies do not include a variable speed fan. You must remove the operational fan from the defective power supply and install the fan on the new power supply. • The fan blades rotate at a high speed and do not stop immediately when power is removed from the MSA. Allow time for the blades to stop rotating. Avoid touching the rotating blades when removing the fan. • The fan shell must be handled carefully to avoid breaking it. Do not press on the center section of the fan shell (circular panel covering the blades). To avoid damaging the fan blades, grasp only the outer portion of the fan shell. Do not rest the power supply on the fan. Doing so might break the fan. Verifying component failure • Check the array controller LCD display panel for error messages. • Verify that the electrical source is delivering power down the AC power cord. • Verify that the blower module fault LED is flashing amber. • Verify that the blower module Power on/off LED is Off. Removing the component 1. Review all warnings, cautions, and preparation procedures as detailed in Warnings and precautions. 2. Push in the two fan tabs (1) while pulling the fan element away from the power supply (2). 88 Customer replaceable components
