Chapter 1 Install the Shelf and Common Control Cards
NTP- G7 Mount Multiple Shelf Assemblies in a Rack
installed above third-party equipment, you must provide a minimum spacing of one inch (25.4 mm)
between the third-party shelf assembly and the bottom of the ONS 15454. The third-party equipment
must not vent heat upward into the ONS 15454.
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’s instructions:
• The fuse rating for both ETSI and ANSI chassis must not exceed 30A.
Step 2
Mount the first shelf assembly in the bottom of the rack using the “DLP-G5 Mount the Shelf Assembly
in a Rack (One Person)” task on page 1-13 or the “DLP-G6 Mount the Shelf Assembly in a Rack (Two
People)” task on page 1-15 .

Ramp for Standard and Deep Door ONS 15454” task on page 1-18 .
The air ramp is needed if you install more than one ONS 15454 ETSI shelf in a rack. To ensure that the
air ramp is secure, use one or two M6 mounting screws for each side of the shelf assembly.
