Replacing the front panel board
Attention: Do not open your server or attempt any repair before reading and understanding “Safety information”
on page iii and “Guidelines” on page 61.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• 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.
• The front panel board is extremely sensitive to ESD. Ensure that you read and understand “Handling
static-sensitive devices” on page 62 first and carefully perform the operation.
To replace the front panel board, do the following:
1. Remove all media from the drives and turn off all attached devices and the server. Then, 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 63.
3. Remove the server cover. See “Removing the server cover” on page 63.
4. Locate the front panel board.
5. Disconnect the front-panel-board cables from the system board. See “System board components”
on page 37.
6. Remove the two screws that secure the front panel board and then carefully remove the front panel
board from the chassis.
