Installing expansion enclosures in the rack

Complete this task to install the expansion enclosures in the rack.

1. Place the expansion enclosure in the rack.
   Note: If you removed the resources, you should be able to lift the unit into the cabinet. If you did not remove the resources before installation, you should have three people that are available to lift the unit into the rack.
   1. Move the expansion enclosure to the front of the rack-mount cabinet.
   2. Slide the unit into the rack.
2. Secure the expansion enclosure to the rack.
   1. Align the front mounting holes on each side of the server with the mounting holes on the front of the support rails.
   2. Insert an M5 hex screw into the mounting hole between the two pins on both sides of the front of the unit. Tighten the screws to secure the front of the expansion enclosure to both of the front cabinet rails.
      
   3. Ensure the rear screw mounting bracket is pushed up against the rear of the chassis. Remove the M5 countersunk screw from the bracket and insert it into the hole in the rear of the chassis. Tighten the screw. Repeat for the opposite side.
