Warning
To prevent the equipment from overheating, do not operate it in an area that exceeds the maximum
recommended ambient temperature of 131°F (55°C). To prevent airflow restriction, allow at least 3
inches (7.6 cm) of clearance around the ventilation openings.
The ONS 15454 is easily mounted in a 19- or 23-inch equipment rack. The shelf assembly projects five
inches from the front of the rack. It mounts in both EIA-standard and Telcordia-standard racks. The shelf
assembly is a total of 17 inches wide with no mounting ears attached. Ring runs are not provided by
Cisco and may hinder side-by-side installation of shelves where space is limited.
The ONS 15454 measures 18.5 inches high, 19 or 23 inches wide (depending on which way the mounting
ears are attached), and 12 inches deep (47 by 48.3 by 30.5 cm). You can install up to four ONS 15454s
in a seven-foot equipment rack. The ONS 15454 must have 1 inch of airspace below the installed
shelf assembly to allow air flow to the fan intake. If a second ONS 15454 is installed underneath
the shelf assembly, the air ramp on top of the lower shelf assembly provides the air spacing needed
and should not be modified in any way. Figure 1-1 shows the dimensions of the ONS 15454.
Note The 10 Gbps compatible shelf assembly (15454-SA-10G) and fan-tray assembly (15454-FTA3) are
required with the ONS 15454 XC10G, OC-192, and OC-48 any slot (AS) cards.
Warning
The ONS 15454 should be installed in the lower rack position or mounted above another ONS
15454 shelf assembly.
