1. Locate the failing hot-swap redundant power supply module on the rear of your server. Then, press the
release tab 1 in the direction as shown and carefully pull the handle 2 at the same time to slide the
redundant power supply module out of the chassis.
Note: Do not use too much strength. You can first carefully slide the redundant power supply module a
little bit out to release it from the secured position. Then, completely slide it out of the chassis.
