For replacement, use the hot-plug procedure supported by your server: confirm redundant configuration or alternative power is available, remove the faulty unit by disengaging its latch, and insert the replacement module until fully seated. After installation, monitor status LEDs and system management software to confirm the supply is operating and recognized by the server.
