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 63.
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.
• Use any documentation that comes with the new front-panel board and follow those instructions in
addition to the instructions in this topic.
• The front-panel board is sensitive to ESD. Ensure that you read and understand "Handling static-sensitive
devices" on page 64 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. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat,
clean, and static-protective surface. See the Rack Installation Instructions that comes with the server.
3. Remove the server cover. See "Removing the server cover" on page 66.
4. Remove the front bezel. See "Removing and reinstalling the front bezel" on page 70.
5. Locate the front panel. See "Front panel" on page 20.
6. Disconnect the front-panel cable from the rear of the front-panel board and from the front panel
connector on the system board. See "System board components" on page 41.
7. If necessary, remove any parts and disconnect any cables that might impede your access to the front
panel cable. Record the cable routing, and then release the front panel cable from any cable clips
or ties in the chassis.
