• If you are replacing a hot-swap redundant power supply, locate the failing power supply in the rear of
your server and then disconnect the power cord from the failing hot-swap redundant power supply.
Note: On each hot-swap redundant power supply, there is a status LED near the power cord
connector. For information about the status LED, see "Hot-swap redundant power supply status
LED" on page 40. If your server comes with an Intelligent Diagnostics Module Premium, you also
can view the LEDs on the panel of the module to locate the failing power supply. See "Diagnostic
module" on page 24.
