Removing a drive drawer entails sliding the drawer part of the way out, recording the locations of the
drives, removing the drives, and removing the drive drawer.
Before you begin
• You have removed the right and left cable chains for the drive drawer.

drive from the drawer.
Steps

2. Unlatch the drive drawer by pulling out on both levers.
3. Using the extended levers, carefully pull the drive drawer out until it stops. Do not completely
remove the drive drawer from the drive shelf.

to note the exact location of each drive. For example, using the following drawing as a reference,
write the appropriate slot number on the top of each drive.
