Note: The tabs on each side of the template show a notch to indicate the correct spacing between
the front flanges.
b.
Locate the dots, printed on the left and right side of the template. Place a self-adhesive dot
directly across from the template's printed dots on or near the rack's EIA numbering strip. You
will be using these dots to help correctly position the rail-alignment pins located on the front of
each rail. Be sure to wrap the dot around the edge of the front flange so it can also be seen when
you move to the rear of the rack.
c. Remove the rack-mounting template from the front of the rack. The front of your rack should now
contain dots.
d. Mount the rack-mounting template to the rack's back EIA frame. Place the rack-mounting template
at the same EIA-numbered location that was used on the front of the rack.
e.
Wrap a self-adhesive dot directly across from the template's printed dots. Ensure that a portion of
the self-adhesive dot wraps around the rack frame so that it can be seen from the front of the rack.
f. Attach two nut clips to the left side of the rack. Position them as shown on the template.
g.
Remove the rack-mounting template from the back of the rack. The back of your rack should now
contain dots that have been partially wrapped around the frame and the nut clips.
3. Attach the rail assembly to the rack. See “Installing the 0595, 5095, or 7311-D20 rails into the rack.”
Marking the location without a rack-mounting template
You might need to mark the location without a template. Use this procedure to perform this task.
To mark the installation location without using a rack-mounting template, complete these steps:
1.
Determine where in the rack to place the system. Record the location.
This unit is five Electronic Industries Alliance (EIA) units high. An EIA unit is 1.75 in. (44.45 mm) in
height. The rack contains three mounting holes for each EIA unit of height. This drawer therefore is
8.75 in. (222.25 mm) high and covers 15 mounting holes in the rack.
2.
Facing the front of the rack and working from the right side, place a supplied self-adhesive dot next
to the top hole of the bottom EIA unit.
Note: The self-adhesive dots are used to aid in identifying locations on the rack. If you do not have
any of the dots, use some other form of marking tool to aid you in identifying hole locations (for
example, tape, a marker, or pencil).
3. Place a self-adhesive dot next to the bottom hole of the next highest EIA unit.
4. Repeat steps 2 through 3 for the corresponding holes located on the left side of the rack.
5.
Go to the back of the rack. On the right side, find the EIA unit that corresponds to the bottom EIA
unit marked on the front of the rack.
6. Move up to the next EIA unit and place another self-adhesive dot next to the middle hole.
7.
Move up one more EIA unit and place a self-adhesive dot next to the middle hole. There are two
holes between the two dots.
8. Mark the corresponding holes on the left side of the rack.
9. Attach two nut clips to the left side of the rack.
a. Put the first nut clip in the top hole of the third EIA unit. There are three holes between this nut
clip and the highest dot on the left side.
b. Put the second nut clip in the middle hole of the fourth nut clip. There is one hole between the
two nut clips.
Installing the 0595, 5095, or 7311-D20 rails into the rack
You might need to install rails into a rack. Use this procedure to perform that task. In addition to
information intended to promote safety and reliable operation, illustrations of the related hardware
components are provided and show how these components relate to each other.
