Facility Requirements
Before installing the device, be sure that the following facility requirements are met.
Table 6: Facility Requirements
Type Requirements
Electrical
•
An adequate supply circuit, line fusing, and wire size, as specified by the electrical rating on the switch
nameplate.
•
A circuit that is protected by a circuit breaker and grounded in accordance with local electrical codes.
See the Technical Specifications section for power supply specifications.
Thermal
•
A minimum airflow of 79.8 cubic meters/hour (47 cubic feet/minute) available in the immediate vicinity of
the switch. Although this airflow may exceed the airflow maximum that is 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 in.) rack.
•
All equipment in the rack grounded through a reliable branch circuit connection.
•
The additional weight of the switch not to exceed the weight limits of the rack.
•
Rack secured to ensure stability if there is unexpected movement.
