Installing the ONS 15454 M2 Shelf
This chapter explains how to install the ONS 15454 M2 shelf.
ANSI Rack Installation
The ONS 15454 M2 shelf is mounted on a 19-inch (482.6-mm) or 23-inch (584.2-mm) equipment rack. Make
sure that the correct type of 19-inch ANSI rack is used for mounting the ONS 15454 M2 shelf as shown in
Figure 1: 19-inch ANSI Rack Post Recommended for Cisco ONS 15454 M6 and M2 Shelves, on page 3 .
If the shelf is mounted in the front position, then it projects 1.7 inches (43.18 mm) from the front of the rack.
If the shelf is mounted in the middle position, then it projects 5.1 inches (129.54 mm) from the front of the
rack. The shelf mounts in both Electronic Industries Alliance (EIA) standard and Telcordia-standard racks.
The shelf is a total of 17.2 inches (431.8 mm) wide with no mounting ears attached. Ring runs are not provided
by Cisco and might hinder side-by-side installation of shelves where space is limited.
The ONS 15454 M2 shelf measures 3.5 inches (88.9 mm) high, 19 or 23 inches (482.6 or 584.2 mm) wide
(depending on which way the mounting ears are attached), and 11.1 inches (304.8 mm) deep.
The following figure shows the dimensions of the ONS 15454 M2 shelf in a 19-inch configuration with
brackets mounted in the front position.
