Step 2. Position the replacement drive drawer in front of the empty slot and slightly to the right of center.
Positioning the drawer slightly to the right of center helps to ensure that the lock-out tumbler and
the drawer guide are correctly engaged.
Step 3. Slide the drive drawer into the slot, and ensure that the drawer guide slides under the lock-out
tumbler.
Attention: Risk of equipment damage – Damage occurs if the drawer guide does not slide under
the lock-out tumbler.
Step 4. Carefully push the drive drawer all the way in until the latch fully engages.
Attention: Risk of equipment damage — Stop pushing the drive drawer if you feel excessive
resistance or binding. Use the release levers at the front of the drawer to slide the drawer back out.
Then, reinsert the drawer into the slot, and ensure that it slides in and out freely.
Step 5. Follow these steps to reinstall the drives in the drive drawer:
a. Unlatch the drive drawer by pulling out on both levers at the front of the drawer.
b. Using the extended levers, carefully pull the drive drawer out until it stops. Do not completely
remove the drive drawer from the drive shelf.
c. Determine which drive to install in each slot by using the notes you made when removing the
drives.
Attention: Possible loss of data access – You must install each drive in its original location
in the drive drawer.
