1.2 Rack Installation
The ONS 15310-MA SDH is easily mounted in a 19-inch (482.6 mm) or 600x600 mm equipment rack.
The shelf assembly can be mounted so that it projects five inches from the front of the rack. It mounts
in both EIA-standard and Telcordia-standard racks. A single shelf assembly is 10.67 inches (27.1 mm)
wide and occupies 6 RUs (10.5 in. [267.6 mm]) in a rack when installed with a standard cable
management bracket. If an extended cable management bracket is installed below the shelf assembly, an
additional RU is occupied, for a total of 7 RUs (12.25 in. [311.1 mm]).
The ONS 15310-MA SDH measures 10.44 inches (26.51 cm) high, 10.67 inches (27.10 cm) wide, and
12 inches (20.48 cm) deep. Figure 1-1 shows the dimensions of the ONS 15310-MA SDH shelf
