Security Level
Note
The ONS 15454 M2 requires a minimum of 3.5 inches (88.9 mm) 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 In an ANSI rack, the chassis can be installed in the front or the middle position. In an ETSI rack, the chassis
is installed only in the front position.
Procedure
Step 1 Verify that the proper fuse panel has been installed in the top mounting space. If a fuse panel is not present,
you must install one according to manufacturer instructions:
• For a DC power supply, the fuse rating must not exceed 15A.
• 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. The recommended 19-inch ANSI rack
for the ONS 15454 M2 shelf is shown in
ONS 15454 M6 and M2 Shelves, on page
• 600 x 600-mm (23.6 x 23.6-inch) or 600 x 300-mm (23.6 x 11.8-inch) for ETSI racks.
