Facility requirements TABLE 8
Type Requirements
Electrical • Primary AC input 100-240 VAC, 2.0A, 47-63 Hz; switch autosenses input voltage
• 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 Power supply specifications on page 46 for complete power supply specifications.
Thermal • A minimum air flow of 79.8 cubic meters/hour (47 cubic ft/min.) available in the immediate
vicinity of the switch
• 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 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
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 a built-in fan for cooling,
pushing air towards the port side of the switch.
