person to install an empty shelf. The shelf should be empty for easier lifting.
Mounting Multiple Nodes
Most standard (Telcordia GR-63-CORE, 19-inch (482.6-mm) or 23-inch (584.2-mm) 7-foot (2.133-m) racks
can hold seven ONS 15454 M6 shelves and a fuse and alarm panel. However, unequal flange racks are limited
to six ONS 15454 M6 shelves and a fuse and alarm panel, or seven ONS 15454 M6 shelves using a fuse and
alarm panel from an adjacent rack. In an ANSI shelf, the brackets can be mounted in the front or middle
position.
The ONS 15454 M6 shelves can be mounted above each other without any space between the shelves. This
method of mounting does not restrict the air flow because the air vents are on either sides of the ONS 15454
M6 shelves.
ETSI Rack Installation
The ONS 15454 M6 shelf is mounted on a 600 x 600-mm (23.6 x 23.6-inch) or 600 x 300-mm (23.6 x

The shelf projects 1.7 inch (43.18 mm) from the front of the rack and is a total of 431.8 mm (17 inch) wide
with no mounting ears attached. Cisco does not provide ring runs, which might hinder side-by-side installation
of shelves where space is limited.
The ONS 15454 M6 shelf measures 264.16 mm (10.4 inches) high, 535 mm (21.06 inches) wide, and 304.8
mm (11.1 inches) deep. You can install up to seven ONS 15454 M6 shelves in a 7-foot (2133.6-mm) equipment
