Power supply specifications

The power supplies are universal and capable of functioning worldwide without voltage jumpers or
switches. They meet IEC 61000-4-5 surge voltage requirements and are autoranging in terms of
accommodating input voltages and line frequencies. Each power supply has built-in fans for
cooling.

ordered from your switch retailer.
The primary outlets are correctly wired, protected by a circuit breaker, and grounded in
accordance with local electrical codes.
The supply circuit, line fusing, and wire size are adequate, as specified by the electrical
rating on the switch nameplate.
The power supply standards provided in

Power Supply Specifications
At a minimum, adequate cooling requires that you install the switch with the intake side,
as indicated by the airflow direction of the fan assemblies, facing the cool-air aisle.
All equipment in the rack should force air in the same direction to avoid intake of exhaust
air.
A maximum of 102 cubic meters/hour (60 cubic feet/minute) and a minimum of 74.8
cubic meters/hour (44 cubic feet/minute) of air flow is available for air intake.
