1.Turn off the computer.

2.Open the cover. See “Opening the cover” on page 12.

3.Rotate the drive bay assembly upward as illustrated.

Note: Make sure you note the location of any cables that you disconnect from the drives or the system board.

4.If any PCI adapters are installed, remove the PCI riser and adapter cards. Do not remove any adapters from the riser card. See “Installing PCI adapters” on page 17.
