Chapter 2 Installing a Sun Fire V440 Server Into a 4-Post Cabinet 11
Locate the Mounting Holes
● Locate and mark the rack rail holes that you will use to attach each slide assembly.
You can either count the holes on the vertical rack rails or use the Rack Alignment
template included with your documentation set. Make sure that each slide assembly
is installed at the same height front-to-back and side-to-side in the rack.
The Rack Alignment template is four rack units (7.00 inch/17.78 cm) tall. You use the
Rack Alignment template to ensure that the server is correctly placed within
standard rack unit spacing, in which the top of the system is defined to be midway
between a set of holes separated by 0.5 inch (1.27 cm).
One side of the Rack Alignment template is for 4-post rackmounting and the other is
for 2-post rackmounting. For 2-post rackmounting instructions, refer to the Sun Fire
V440 Server 2-Post Rackmounting Guide included on your Documentation CD.
The 4-post mounting holes on the Rack Alignment template are for mounting the
slide assembly brackets to the vertical rack rails. The upper and lower retainer screw
openings in the template locate the chassis bracket screws that secure the server in
the rack after the server is installed.
The following figure shows both sides of the Rack Alignment template.
