Reversible Mounting Bracket
Caution! Use only the fastening hardware provided with the ONS 15454 to prevent loosening, deterioration,
and electromechanical corrosion of the hardware and joined material.
Caution! When mounting the ONS 15454 in a frame with a nonconductive coating (such as paint, lacquer, or
enamel) either use the thread-forming screws provided with the ONS 15454 shipping kit, or remove the
coating from the threads to ensure electrical continuity.
The shelf assembly comes preset for installation in a 23-inch (584.2 mm) rack, but you can reverse the
mounting bracket to fit the smaller 19-inch (482.6 mm) rack.
Mounting a Single Node
Mounting the ONS 15454 in a rack requires a minimum of 18.5 inches (469.9 mm) of vertical rack space and
one additional inch (25.4 mm) for air flow. To ensure the mounting is secure, use two to four #12-24
mounting screws for each side of the shelf assembly. Figure 1-2 shows the rack mounting position for the
ONS 15454.
