18. Tighten all mounting screws. The shelf with extender brackets will have six
screws: one on each front rail and two on each rear rail. The shelf without
extender brackets will have four screws: one on each of the four mounting
rails. If you do not have enough room to use a screwdriver to tighten the
screws, use the 10-mm, open-end wrench.
19. After the shelf is installed, you must install the front safety bar. The safety bar
helps prevent equipment on the shelf from being accidentally pushed or slid
off the front of the shelf. To install the safety bar:
a. Install one clip nut in each front mounting rail. Install the nuts in the holes
just above where the shelf is mounted, with the nuts toward the rear of
the rack. Make sure that you install the nuts at the same level on the two
mounting rails.
b. Hold the shelf safety bar level across the front of the rack.
c.
Line up the holes on the ends of the bar with the holes in which the nuts
are installed.
d. Insert two screws through the holes in the front flanges. Loosely thread the
screws into the nuts in the front mounting rails.
e. Tighten the two mounting screws.
20.
Reinstall the side panels, if they were removed.
The shelf installation is complete. You can now install your equipment on the shelf.
Attach the cable tie clips and cable ties after you have installed your equipment on
the shelf.
Removing the Shelf from the Rack
To remove the shelf from the rack, reverse the steps in the installation procedure.
