Mounting Precautions

When you put a hub into a rack, follow these mounting precautions:

■ The rack or cabinet should be adequately secured to prevent it from

becoming unstable and/or falling over. The first hub (or single hub) should

be mounted in a position toward the bottom of the rack for stability and

to make it easier to stack the other hubs on top.

■ Before mounting a hub, plan its location and orientation relative to other

devices and equipment. Also consider the cabling that will be attached to

the hub and the ports that will be used. Verify that there is room for the

grouped cables to trail out from the side of the hub. Allow at least 2.54 cm

(1 inch) in the front of the hub. In the back of the hub, allow at least 3.8

cm (1 1/2 inches) of space for the power cord.

■ Ensure that the HP Switching Hub(s) do not overload the power circuits,

wiring, and over-current protection. To determine the possibility of over-

loading the supply circuits, add together the amperage ratings from the

nameplates of all your hubs (and other equipment) installed on the same

circuits and compare the total with the rating limits for the supply circuits.

■ Make sure that the power source circuits are properly grounded, then use

the supplied power cord to connect the HP Switching Hub to the circuit.

See the Safety Statements in this chapter.

■ Do not install the hub in an environment where the operating ambient

temperature might exceed 55°C (131°F).

■ Make sure the air flow around the sides of the hub is not restricted.
