INSTALLING THE N1 INTO THE RACK
You should now have rails attached to both the chassis and the rack unit. The next step is to install the server into the rack. Line up
the rear of the chassis rails with the front of the rack rails and slide the chassis rails into the rack rails, keeping the pressure even on
both sides (you may have to depress the locking tabs when inserting). See Figure 1-3.
When the server has been pushed completely into the rack, you should hear the locking tabs "click".
