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

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