4.7 Guide Rail Plate Installation
4.7 Guide Rail Plate Installation
Two round standoffs on each end of the guide rail plate are used to locate
the guide rail plate along the cabinet vertical uprights. The round standoffs
are inserted into front and rear cabinet vertical upright mounting holes to
position the guide rail plate while it is fastened to the cabinet. Guide rail plate
installation procedures for both left and right enclosure mounting positions are
presented in Sections Section 4.8 and Section 4.9.
If an ESD bolt is mounted to the vertical upright in your selected installation
position, remove the ESD bolt until your installation is complete, then fasten it to
an open space on the cabinet vertical upright.
4.8 Left Position Guide Rail Plate Installation
Install the guide rail plate in the left position within the cabinet as follows (refer
to Figure 4–5):
WARNING
Cabinet vertical upright edges may be sharp and can slice or abrade skin
or cable insulation.
1. Turn the cabinet power off as described in Section 4.6
2. This procedure installs an enclosure in add-on sequence position 3. Refer
to Figure 4–2 to select the optimum add-on sequence position for your
installation.
3. Open the front cabinet door.
4. Remove the rear panel.
5. From the cabinet door, remove the bezel filler that corresponds to add-on
sequence position 3.
a. Remove the four U-clips securing the bezel filler to the door.

WARNING
Use care in supporting the guide rail plate. It is heavy and awkward to
position within the cabinet. If possible, use two persons to support and
position the guide rail plate. The guide rail plate may cause personnel
injury if dropped during installation.
6. Install the guide rail plate in add-on sequence position 3. Add-on sequence
position 3 corresponds to mounting hole numbers 65, 71, and 78 as shown in
Figure 4–6.
a. From the rear of the cabinet, position the guide rail plate with the
mounting bracket to the rear, making sure that the arrow on the
mounting bracket is pointing up.
b. Insert the two front round stand-offs into the cabinet so that hole 71
becomes the center mounting hole in the guide rail plate.
