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

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.
