Lenovo ThinkSystem DE Series Installation Instructions Manual page 12

5. Install the drives.
a. Wrap the strap end of the ESD wristband around your wrist, and secure the clip end to a
metal ground to prevent static discharges.
b. Starting at the front left slot of the top drawer, install each drive by gently positioning into
the drive slot and lowering the raised drive handle until it clicks into place.

If you are installing fewer than 60 drives, if you have solid-state drives
(SSDs), or if your drives have different capacities:
◦ Maintain a minimum of 20 drives per shelf. Install drives in the front four slots in each
drawer first, for adequate airflow for cooling.
◦ Distribute any remaining drives across the drawers. If possible, install an equal number
of each type of drive in each drawer to allow for the creation of Drawer Loss Protected
volume groups or disk pools.
◦ Distribute any SSDs evenly across the drawers.
c. Carefully slide the drawer back in by pushing the center and gently closing both latches.
d. Attach the front bezel.
