Installing the Outer Rails onto the Rack

1. Press upward on the locking tab at the rear end of the middle rail.
2. Push the middle rail back into the outer rail.
3. Hang the hooks on the front of the outer rail onto the square holes on the front of the rack.
If desired, use screws to secure the outer rails to the rack.

rack.

Note: The figure above is for illustrative purposes only. Always install servers at the bottom
of the rack first.
Stability hazard. The rack stabilizing mechanism must be in place, or the rack must
be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the
rack can cause the rack to tip over.
Do not use a two post "telco" type rack.
