Table 3. Facility requirements
Type Requirements
Electrical • Adequate supply circuit, line fusing, and wire size, as specied 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 Specications at the end of this guide for complete
power supply specications.
Thermal • A minimum airflow of 79.8 cubic meters/hour (47 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 Specications, 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
