Hard-Disk Drive Bracket Removal
To remove the hard-disk drive bracket, follow these steps:
1. Disconnect the DC power cable and the interface cable from the back of each hard-disk drive installed in the hard-disk drive bracket.
2. Remove the screw that secures the hard-disk drive bracket to the drive cage in the chassis.
3. Grasp the bracket, and rotate it outward from the chassis until the sliding tab clears the slide rail on the drive cage.
4. Lift the hard-disk drive bracket up slightly to free the hinge tabs and remove the bracket from the computer.
When you reinstall the hard-disk drive bracket, insert the bracket's hinge tabs into the chassis slot so that the tabs hook over the slot. Then rotate the bracket toward
the drive cage, and fit the bracket's sliding tab on the drive-cage slide rail.

drive.
