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 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. If you are using a Redundant
Power Supply, allow the appropriate amount of space for the RPS
connector.
■
Ensure that the HP Hub-16M does 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 name-
plates 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 Hub-16M to the circuit.
See
the Safety Statements in this chapter.
■
Do not block airflow around the side and the back of the unit.
