Facility requirements

Before installing the device, be sure the following facilities requirements are met.

Table 1. Facility requirements
Type	Requirements
Electrical	Adequate supply circuit, line fusing, and wire size, as specified by the electrical rating on the switch nameplate Circuit protected by a circuit breaker and grounded in accordance with local electrical codes Refer to the Technical Specifications at the end of this guide for complete power supply specifications.
Thermal	A minimum airflow of 54.5 cubic meters/hour (32.1 cubic ft/min.) available in the immediate vicinity of the switch Note: Although this airflow may exceed the airflow maximum listed in the device Technical Specifications, the additional airflow is recommended to pressurize the inlet (cool isle) side of rack installations relative to the exhaust side to minimize recirculation of hot air back to the inlet side. Ambient air temperature not exceeding 40°C (104°F) while the switch is operating
Rack (when rack-mounted)	One rack unit (1U) in a 48.3 cm (19-inch) rack All equipment in the rack grounded through a reliable branch circuit connection Additional weight of switch not to exceed the rack’s weight limits Rack secured to ensure stability in case of unexpected movement
