• Depending on the model, your server might look slightly different from the illustrations in this topic.
• The illustrations in the following procedure show the front panel board for 3.5-inch hard disk drives. For
the front panel board for 2.5-inch hard disk drives, the replacement procedure is similar.

static-sensitive devices" on page 56 first and carefully perform the operation.

disconnect all power cords from electrical outlets and disconnect all cables that are connected to
the server.
2. Prepare your server. See "Removing or extending the server from the rack cabinet" on page 57.
3. Remove the server cover. See "Removing the server cover" on page 57.
