(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 2. Refer
to Figure 4–2 to select the optimum add-on sequence position for your
installation.
3. Open the front cabinet door and remove the rear panel.
4. From the cabinet door, remove the bezel filler that corresponds to add-on
sequence position 2.
a. Remove the four U-clips securing the bezel filler to the door.
b. Remove the bezel filler.
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.
Note
Removing the door latch applies only to installing guide rail plates in
position 2.
5. Remove two mounting screws and kepnuts securing the door latch to cabinet
and remove the door latch.

position 2 corresponds to mounting hole numbers 65, 71, and 78 as shown in
Figure 4–6.

mounting bracket to the front, making sure that the arrow on the
mounting bracket is pointing up.
b. Insert the two rear round stand-offs into the cabinet so that hole 71
becomes the center mounting hole in the guide rail plate.
