16 Chapter 1 Installing the Xserve
Step 4: Align and Secure the Rails
To make sure the Xserve slides easily in and out of the rack, use the alignment guide to
position the rails in the rack before tightening the mounting screws.
1 Insert the alignment guide in the front of the rails.
2 Tighten the front mounting screws
Important: If you have a square-hole rack, make sure the raised alignment block on the
back of each mounting spacer is seated properly in the hole in the rack post as you
tighten the screws.
3 Tighten the rear mounting screws.
4 Remove the alignment guide.
Insert the alignment
guide into the rails
and tighten all the screws.
