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. At the back

of the hub, allow at least 3.8 cm (1 1/2 inches) of space for the

power cord.

•

Ensure that HP 100Base-T Hubs do not overload the power

circuits, wiring, and over-current protection. To determine the

possibility of overloading 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 100Base-T

Hub to the circuit. See the Safety Statements in this chapter.

• Do not install the hub in an environment where the operating

ambient temperatures might exceed 55

C (131

F).

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