Notes:
• The hot-swap hard-disk-drive backplane is sensitive to ESD. Ensure that you read and understand
“Handling static-sensitive devices” on page 66 first and carefully perform the operation.
• Depending on the model, your server might look slightly different from the illustrations in this topic.
To replace the hot-swap hard-disk-drive backplane, 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. Remove the server cover. See “Removing the server cover” on page 67.
3. Remove the front bezel. See “Removing and reinstalling the front bezel” on page 69.
4. Locate the hot-swap hard-disk-drive backplanes. See “Hot-swap hard-disk-drive backplane” on page
32.
5. Remove the front system fan 1. See “Replacing the front system fan 1” on page 144.
6. Remove all the installed hot-swap hard disk drives and dummy trays (if any) from the hard-disk-drive
cage. See “Installing or replacing a hot-swap hard disk drive” on page 117.
7. Record the cable connections on the backplane, and then disconnect all the cables from the backplane.
