Fahrenheit) while the switch is operating.
Caution:
Do not block air vents. The switch uses ambient air for cooling.
Primary AC Input 100–240 VAC (switch auto-senses input voltage) 47–63 Hz
Correctly wired primary outlet, with circuit protected by a circuit breaker and
grounded in accordance with local electrical codes
Adequate supply circuit, line fusing, and wire size, as specified by the
electrical rating on the switch nameplate
Voltage capability of 85–264 VAC

The cabinet must be a standard EIA cabinet.
Plan a cabinet space that is 1.5 rack units high (2.6 inches; 6.7 cm), 19 inches
(48.3 cm) wide, and at least 23 inches (68.6 cm) deep.
