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 according to manufacturer instructions:
• For 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. The recommended 19-inch ANSI rack
for the ONS 15454 M6 shelf is shown in Figure 1.
• 600 x 600-mm (23.6 x 23.6-inch) or 600 x 300-mm (23.6 x 11.8-inch) for ETSI racks.
