None Security Level
The ONS 15454 M6 requires a minimum of six RU of vertical rack space. To ensure that the mounting is
secure, use two to three M6 mounting screws on each side of the shelf. A shelf should be mounted at the
bottom of the rack if it is the only unit in the rack. Note
Procedure
Step 1
Verify that the proper fuse and alarm panel has been installed in the top mounting space. If a fuse and alarm
panel is not present, you must install one as per the instructions of the manufacturer:
• For a a DC power supply, the fuse rating must not exceed 40A.
• For an AC power supply, the fuse rating must not exceed 10A, 15A, or 20A. For North America, the
branch circuit protection must be rated 20A. The overcurrent/short circuit protection must be in accordance
with local and national electrical codes.
Step 2
Ensure that the shelf is mounted on the appropriate rack equipment:
• 23-inches (584.2 mm) or 19-inches (482.6 mm) for ANSI racks.
• 600 x 600-mm (23.6 x 23.6-inch) or 600 x 300-mm (23.6 x 11.8-inch) for ETSI racks.
Step 3
Lift the shelf to the desired position in the rack. If the rack is empty, place the shelf at the bottom of the rack.
The placement of the shelf is dependent on where you want to install the new equipment in the rack.
To ensure proper cooling of the ONS 15454 M6 shelf, make sure that the space in front of the air
flow vents are free of cables, fibers, and mechanical fixtures for fiber and cable management. Note
Step 4 Align the screw holes on the mounting brackets with the mounting holes in the rack.
Step 5 Have one person hold the shelf in place while the other person uses the Phillips Dynamometric screwdriver
to install one mounting screw in each side of the assembly. Tighten the screw to a torque value of 22 in-lb
(2.5 N-m).
Step 6
When the shelf is secured to the rack, install the remaining mounting screws.
Use at least one set of the horizontal screw slots on the shelf to prevent slippage. Note
Step 7
Return to your originating procedure (NTP).
