Replacing the 3.5-inch simple-swap backplate assembly/hot-swap hard disk drive backplane

Use this information to replace the 3.5-inch simple-swap backplate assembly/hot-swap hard disk drive backplane.

1. Read the safety information that begins on Safety and Installation guidelines.
2. Turn off the server, and disconnect all power cords and external cables.
3. Remove the top cover (see Removing the top cover).
4. Pull the hard disk drives or fillers out of the server slightly to disengage them from the backplate assembly/backplane. See Removing a hot-swap hard disk driveand Removing a simple-swap hard disk drive for details.
5. Remove the fan cage assembly (see Removing the fan cage assembly).
6. 1 Insert the backplate assembly/backplane tabs into slots on the bottom of the drive cage at an angle; then, 2 rotate the backplate assembly/backplane toward the front the server.
