Installing the SAN Switch 2/32 Follow these guidelines to ensure proper air flow, and prevent component overheating: ■ To ensure adequate cooling, install the switch with the non-port side, which contains the air intake vents, facing the cool-air aisle. ■ Verify a minimum of 47 cubic feet/minute (79.8 cubic meters/hour) of air flow is available to the air intake vents on the non-port side of the switch. ■ Verify that the ambient air temperature does not exceed 40° Celsius (104° Fahrenheit) while the switch is operating. Caution: Do not block air vents. The switch uses ambient air for cooling. Power Requirements Two AC power cords connect to the switch on either side of the rear panel. The AC power source must meet these requirements: ■ 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 ■ Input voltage frequency of 47-63 Hz ■ Power capability of 75 W maximum The switch has a universal power supply capable of functioning worldwide without voltage jumpers or switches. The power supply is auto ranging in terms of accommodating input voltages and line frequencies. SAN Switch 2/32 Installation Guide 29

SAN Switch 2/32 Installation Guide
Follow these guidelines to ensure proper air flow, and prevent component
overheating:
■
To ensure adequate cooling, install the switch with the non-port side, which
contains the air intake vents, facing the cool-air aisle.
■
Verify a minimum of 47 cubic feet/minute (79.8 cubic meters/hour) of air
flow is available to the air intake vents on the non-port side of the switch.
■
Verify that the ambient air temperature does not exceed 40
°
Celsius (104
°
Fahrenheit) while the switch is operating.
Caution:
Do not block air vents. The switch uses ambient air for cooling
.
Power Requirements
Two AC power cords connect to the switch on either side of the rear panel. The
AC power source must meet these requirements:
■
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
■
Input voltage frequency of 47–63 Hz
■
Power capability of 75 W maximum
The switch has a universal power supply capable of functioning worldwide
without voltage jumpers or switches. The power supply is auto ranging in terms of
accommodating input voltages and line frequencies.
