Safety Precautions

Installation Precautions

WARNING:

• The rack or cabinet should be adequately secured to prevent it from becoming unstable, tilting,

or falling. Devices installed in a rack or cabinet should be mounted as low as possible, with the

heaviest devices at the bottom and progressively lighter devices above.

• Do not wall-mount any switch without checking for restrictions in the Installation and Getting

Started Guide at http://www.hpe.com/networking/ResourceCenter. Wall-mount the switch

with network ports facing up or down (away from or toward the floor). Do not wall-mount the

switch with the ventilation holes facing up or down.

CAUTION:

• Ensure the power source circuits are properly grounded, then use the power cord supplied with

the switch to connect to the AC power source.

• If your installation requires a different power cord than the one supplied with the switch and/or

power supply, be sure the cord is adequately sized for the switch’s current requirements. In

addition, be sure to use a power cord displaying the mark of the safety agency that defines the

regulations for power cords in your country/region. The mark is your assurance that the power

cord can be used safely with the switch and power supply.

• When installing the switch, the AC outlet should be near the switch and should be easily

accessible in case the switch must be powered off.

• Ensure that the switch does not overload the power circuits, wiring, and over-current protection.

To determine the possibility of overloading the supply circuits, add together the ampere ratings of

all devices installed on the same circuit as the switch, and compare the total with the rating limit

for the circuit. The maximum ampere ratings are usually printed on the devices near the AC

power connectors.

• Do not install the switch in an environment where the operating ambient temperature exceeds its

specification.

• Ensure that the air flow around the switch is not restricted. Leave at least 7.6 cm (3 inches) for

cooling.
