Attaching Outer Rails to the Rack
23
2.
Determine and mark the proper left-front, left-rear, right-front, and right-rear rack flange square-hole pairs
for the desired vertical location of the node’s sides.
3.
Locate the left or right rail outer section and position it on the corresponding side of the rack.
4.
Position the rail so the extensible mechanism of the rail extends toward the front.
5.
While maintaining the position described previously in Step 4 on page 23, locate the side of the rail
that receives the inner portion of the chassis rail. Position the rail so that side faces the interior equipment
area of the rack.
6.
Locate the narrow front face of the rail with the two black spring-loaded locks and two hooks. If the
previous steps were performed correctly, the hooks face downward. If they are not facing downward, do
not proceed without first correcting the error.
7.
Position the narrow front face of the rail behind the front square-hole rack flange so the two black spring-
loaded locks are in contact with the material immediately above each desired square hole as determined in
Step 2 on page 23.
8.
Push the rail towards the front of the rack so the two black spring-loaded locks retract into the rail and the
two hooks protrude through the two square holes.
9.
While maintaining pressure on the rail, push the rail down until the two rail hooks engage the bottom edge
of the two square holes and the two black spring-loaded locks snap through the same two square holes that
the hooks have engaged. Ensure that the two black spring-loaded locks keep the hooks from disengaging,
effectively locking the rail to the rack flange. Pull upward on the rail to verify that the hooks cannot be
disengaged from the square holes.
10. Extend the rear portion of the rail toward the rear of therack.
11. Position the narrow rear face of the rail behind the rear square-hole rack flange so the two black spring-
loaded locks are in contact with the material immediately above each desired square hole as determined in
Step 2 on page 23.
12. Push the rail towards the rear of the rack so the two black spring-loaded locks retract into the rail and the
two hooks protrude through the two square holes.
13. While maintaining pressure on the rail, push the rail down until the two rail hooks engage the bottom edge
of the two square holes and the two black spring-loaded locks snap through the same two square holes that
the hooks have engaged. Ensure that the two black spring-loaded locks keep the hooks from disengaging,
effectively locking the rail to the rack flange. Pull upward on the rail to verify that the hooks cannot be
disengaged from the square holes.
14. Locate the eight (8) flat-head countersunk screws and the eight (8) conical washers. Insert a screw through
a washer with the narrow end of the screw’s countersink and the narrow end of the conical washer facing
the same direction. Install the screw through the square hole in the rack that is aligned with the uppermost
threaded hole in front of the left rail assembly. Insert another screw through a washer, and install the
screw through the square hole in the rack that is aligned with the lowermost threaded hole in front of the
left rail assembly. Using the six (6) remaining screws and six (6) conical washers, repeat the steps for the
left-rear, right-front and right-rear rail assemblies.
If the screws are installed in the correct holes, one empty threaded hole remains between
the two screws at the front and rear of each rail assembly. The front threaded holes are for
securing the node after it is installed.
