Power UID module Before you begin CAUTION: • Before removing the failed component, make sure that you have the replacement part available. Removing a component impacts the airflow and cooling ability of the device. • Do not remove more than one component or blank from the enclosure at a time. Doing so impacts the airflow and cooling ability of the device. To avoid possible overheating, insert the new or replacement component as quickly as possible. If the internal temperature exceeds acceptable limits, the MSA70 may overheat and automatically shut down or restart. • Parts can be damaged by electrostatic discharge. Use proper anti-static protection. Verifying component failure Use the following methods to verify component failure: • Check the power UID module status LED: Blue = Identified Blue flashing = Active remote management Off = No active remote management • Check the host log for errors. Removing the power UID module 1. Power down the enclosure: a. Power down any attached servers. See the server documentation. b. Press the Power On/Standby button on the enclosure. c. Wait for the system power LED to go from green to amber. d. Disconnect the power cords. 2. Extend or remove the enclosure from the rack in which it may be installed: a. Loosen the front panel thumbscrews that secure the enclosure faceplate to the front of the rack. b. Disconnect the cabling and extend or remove the enclosure from the rack. 3. Remove the access panel: a. Lift the access panel latch (1). b. Slide the access panel to the rear (2). Removal and replacement procedures 39
