2. Mount the PS 123 on the rack shelf, using two 4-40 x 3/16"
screws in opposite (diagonal) corners.
3. If necessary, mount the half rack width false front panel
(included with the Universal Rack Shelf only) and/or the
quarter rack width false front panel (included with the
PS 123) to the shelf, using two 4-40 x 3/16" screws in the
front holes for each panel.
Under-desk mounting
In addition to using the PS 123 power supply on a rack or
projector, it can also be mounted under furniture (such as a
desk) using the MBU 125 Under-Desk Mounting Kit (part
#70-077-01). To mount the PS 123 under a desk or other
furniture, follow these steps:
1. Attach the mounting brackets to the power supply with
the provided machine screws (figure 9).
2. Hold the power supply with the attached brackets against
the underside of the furniture. Mark the location of the
screw holes of the bracket on the mounting surface.
3. Drill 3/32" (2 mm) diameter pilot holes, 1/4" (6.3 mm)
deep in the mounting surface at the marked screw
locations.
4. Insert #8 wood screws into the four pilot holes. Tighten
each screw into the mounting surface until just less than
1/4" of the screw head protrudes.

5. Align the mounting screws with the slots in the brackets
and place the power supply against the surface, with the
screws through the bracket slots.
6. Slide the unit slightly forward or back, then tighten all four
screws to secure it in place.
