The ONS 15454 SDH requires 616.5 mm (24.24 inch) minimum of vertical rack space and 25 mm
Note
(1 inch) below the installed shelf assembly to allow air flow to the fan intake. If a second
ONS 15454 SDH is installed above a shelf assembly, the air ramp between the shelves provides space
for air flow. To ensure the mounting is secure, use two to four M6 mounting screws for each side of the
shelf assembly. A shelf assembly should be mounted at the bottom of the rack if it is the only unit in the
rack.
Verify that the chassis fuses rating does not exceed 30A.
Step 1
Ensure that the shelf assembly is set for the desired rack size.
Step 2
Using the hex tool that shipped with the assembly, install the temporary set screws into the holes that

Lift the shelf assembly to the desired position in the rack.
Step 4
Align the screw holes on the mounting bracket with the mounting holes in the rack.
Step 5
Have one person hold the shelf assembly in place while the other person installs one mounting screw in
Step 6
each side of the assembly using the Phillips screwdriver.
When the shelf assembly is secured to the rack, install the remaining mounting screws.
Step 7
