If both power supplies need to be replaced, then a power-down is required. Unplug the
AC cord from the module to be replaced.
2.
On the back of the module, push the release tab to the right, as shown.
3. Pull the module out using the handle.
4. Push the new power supply module into the power bay until it clicks. Replace with the
same model.
5. Plug the AC power cord back into the module.
