Rotate the drives counterclockwise 90 degrees, then reinstall them into the drive bays.

When the drives are properly inserted, the drivelock will secure them.

IMPORTANT:

The diskette drive should always be placed in the bay nearest the top of the chassis in the

desktop configuration for proper drive clearance and access.

Figure 3-50. Installing a drive in the desktop configuration

Reconnect the power and data cables to the drives.
