When installed in an equipment rack, the Cisco ONS 15454 M2 shelf is typically connected to a fuse panel
to provide distributed power for the ONS 15454 M2. The fuse panel is a third-party equipment and is not
described in this documentation. If you are unsure about the requirements or specifications for a fuse, consult
the user documentation for the related equipment.
Install and operate the ONS 15454 M2 only in environments that do not expose wiring or cabling to the outside
plant.
Two types of front doors can be attached to the Cisco ONS 15454 M2 shelf— the standard door and the deep
door. The front door provides access to the shelf, and acts as a protective panel. The deep door provides
additional space in front of the shelf to accommodate cables that do not fit inside the standard door. The deep
door does not have a hinge and cannot be rotated like the standard door.
You can mount the ONS 15454 M2 on a 19-inch or 23-inch ANSI rack (482.6 or 584.2 mm), or on a 600 x
600-mm (23.6 x 23.6-inch) or 600 x 300-mm (23.6 x 11.8-inch) ETSI standard equipment rack. The ONS
15454 M2 shelf can also be wall mounted or desktop mounted. The shelf weighs approximately 11.02 pounds
(5 kg) with no cards installed.
It is mandatory that the correct type of 19-inch ANSI rack is chosen to mount the ONS 15454 M2 shelf. The
recommended shape of the rack post is shown in

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
