• The hot-swap hard disk drive backplane is sensitive to ESD. Ensure that you read and understand

power cords from electrical outlets and disconnect all cables that are connected to the server.
2. Remove the server cover. See "Removing the server cover" on page 65.
3. Remove the front bezel. See "Removing and reinstalling the front bezel" on page 67.
