Table 9. Facility requirements (continued) Type Requirement Cabinet (when rack-mounted) v One rack unit (1U) in a 48.3 cm (19-inch) cabinet-must use the slim-rail rack kits designed for the extra width of the switch to mount in standard cabinets/racks v All equipment in cabinet grounded through a reliable branch circuit connection v Additional weight of switch not to exceed the cabinet's weight limits v Cabinet 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 built-in fans for cooling.

Power supply specifications Specification Value Input voltage Range: 85-264 VAC Auto-volt, Nominal: 100-240 VAC, 2.0A, 47-63 Hz; switch autosenses input voltage. Input frequency Range: 47-63 Hz; Nominal: 50-60 Hz. Inrush current Limited to 50A peak @ 240Vac for any initial current surge or spike of 10ms or less at cold start-up. Any additional inrush current surges or spikes in the form of AC cycles or multiple AC cycles greater than 10ms, and less than 150ms, must not exceed 15A peak.

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. Table 10 lists the
power supply specifications for the switch.
