Cooling Requirements; Power Requirements - HP StorageWorks SAN Switch 2/32 Installation Manual

Cooling Requirements

Cooling air is drawn into the switch chassis by the fans mounted on the rear of the
chassis. The air is expelled through vents in the front (port side) of the chassis, next to
the HP logo. HP recommends installing the switch so that air intake and exhaust for all
components in the rack is flowing in the same, "front-to-back" direction.
IMPORTANT: HP highly recommends mounting the switch in a cabinet or rack so that the fans
reside in the front of the cabinet, and the ports (cables) reside in the rear of the cabinet.
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°
Farenheit) 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.
