Lenovo RD540 manual Replacing a hot-swap redundant power supply, Removing the shield

Note: If your server comes with one hot-swap power supply installed in the power supply bay 1 (the bay number is marked on the rear of the chassis) and you are installing a hot-swap redundant power supply to provide redundant power, you need to remove the shield that protects the power supply bay 2 first and save the shield for future use. Insert a finger into the hole in the metal shield, press the tab 1 in the direction as shown, and then pull the shield out of the chassis.
