Replace External Rear Components; Removing A Psu From The Chassis - IBM Slicestor 2212A Appliance Manual

Replace external rear components

Replace a power supply unit
If either of the two power supply units (PSU) fails, the other unit takes the full load and the system can
continue operation without interruption. The Power Supply icon on the control panel flashes until the
failed unit is replaced.
The power supply modules have a hot-swap capability; you can replace the failed module without
powering down the system. The redundant feature keeps the appliance online while the failed hot-swap
module is replaced.
1. Push the release tab on the rear of the PSU, as shown in the following figure.
