Figure 1-3 Mounting an ONS 15454 in a rack
Two people should install the shelf assembly; however, one person can install it using the temporary set
screws included. The shelf assembly should be empty for easier lifting. The front door can also be
removed to lighten the shelf assembly (see the “Remove the Front Door” procedure on page 1-13).
Note If you are installing the fan-tray air filter using the brackets provided, mount the brackets on the
bottom of the shelf assembly before installing the ONS 15454 in a rack.
Procedure: Mount the Shelf Assembly in a Rack (One Person)
Step 1 Ensure that the shelf assembly is set for the desired rack size (either 19 or 23 inches).
Step 2 Using the hex tool that shipped with the assembly, install the set screws into the screw holes that will
not be used to mount the shelf.
Step 3 Lift the shelf assembly to the desired rack position and set 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 to prevent future slippage.
Step 7 Remove the temporary set screws.
