Rack Installation
Figure 1-2 Mounting an ONS 15454 SDH in a rack
The shelf assembly is most easily installed by two people. However, you can install it alone by using
temporary set screws. Reduce extra weight if possible by emptying the shelf assembly and removing the
front door. (See the “Remove the Front Door” Procedure on page 1-14).
Procedure: Mount the Shelf Assembly in a Rack (One Person)
Step 1 Choose one or two mounting hole(s) on each side where the mounting brackets will be inserted.
Step 2 Using the hex tool that was included with the assembly, install temporary set screws into the holes that
will not be used to mount the shelf. Let the set screws protrude sufficiently to hold the mounting
brackets.
Step 3 Lift the shelf assembly to the desired rack position and place it on the set screws.
Step 4 Align the screw holes on the mounting ears with the mounting holes in the rack.
Step 5 Install one mounting screw in each side of the assembly.
Step 6 When the shelf assembly is secured to the rack, install the remaining mounting screws.
Note Use at least one set of the horizontal screw slots on the ONS 15454 SDH to prevent future
slippage.
