It is mandatory that the correct type of 19-inch ANSI rack is chosen to mount the ONS 15454 M6 shelf. The
recommended shape of the rack post is shown in Figure 1: 19-inch ANSI Rack Post Recommended for Cisco
ONS 15454 M6 and M2 Shelves, on page 3. For proper airflow and cooling of the shelf, the shape of the
vertical posts of the rack should be such that the airflow vents are not covered. There must be sufficient space
between the shelf side walls, and the vertical walls of the rack post that are parallel to the shelf side walls, as
shown in Figure 2: 19-inch Rack Opening for Air Flow, on page 4.
When installed in an equipment rack, the Cisco ONS 15454 M6 shelf is typically connected to a fuse and
alarm panel to provide centralized alarm connection points and distributed power for the ONS 15454 M6.
Fuse and alarm panels are third-party equipment and are not described in this documentation. If you are unsure
about the requirements or specifications for a fuse and alarm panel, consult the user documentation for the
related equipment.
The shelf with preinstalled air filter weighs approximately 23.55 pounds (10.680 kg) with no cards installed.
Install and operate the ONS 15454 M6 only in environments that do not expose wiring or cabling to the outside
plant.
