Installing a drive drawer

Installing a drive drawer into a drive shelf entails sliding the drawer into the empty slot, installing the drives, and replacing the front bezel.

1. From the front of the drive shelf, shine a flashlight into the empty drawer slot, and locate the lock-out tumbler for that slot.

   The lock-out tumbler assembly is a safety feature that prevents you from being able to open more than one drive drawer at one time.

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.
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.
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.
5. Follow these steps to reinstall the drives in the drive drawer:
   1. Unlatch the drive drawer by pulling out on both levers at the front of the drawer.
   2. Using the extended levers, carefully pull the drive drawer out until it stops. Do not completely remove the drive drawer from the drive shelf.
   3. 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.

      
   4. Raise the handle on the drive to vertical.
   5. Align the two raised buttons on each side of the drive with the notches on the drawer.

   6. Lower the drive straight down, and then rotate the drive handle down until the drive snaps into place.
      
      
      
   7. Repeat these substeps to reinstall all of the drives.
6. Slide the drawer back into the drive shelf by pushing it from the center and closing both levers.
   Attention

   Risk of equipment malfunction – Make sure to completely close the drive drawer by pushing both levers. You must completely close the drive drawer to allow proper airflow and prevent overheating.
7. Attach the bezel to the front of the drive shelf.
