Chapter 1 Install the Shelf and Backplane Cable
NTP-A2 Install the Shelf Assembly
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
1 inch (25.4 mm) of clearance around the ventilation openings.
Warning The ONS 15454 should be installed in the lower rack position or mounted above another ONS 15454
shelf assembly.
Warning The ONS 15454 must have 1 inch of airspace below the installed shelf assembly to allow air flow to
the fan intake. The air ramp (the angled piece of sheet metal on top of the shelf assembly) provides
this spacing and should not be modified in any way.
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.
