Installation Precautions
■
Wall-mount the switches with network ports facing up (away from
the floor) or down (toward the floor). Do not wall-mount any of
the switches with the ventilation ducts facing up or down.
Use only the AC/DC power adapter supplied with the switch for
■
connection to an AC power source.
■
If your installation requires a different power cord than the one supplied
with the switch, ensure 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. The mark is your assurance that the power cord can be
used safely with the switch. If the supplied power cord does not fit,
contact HP networking support.
■
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 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. 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 might exceed 40°C (104°F). This includes a fully-enclosed
rack. Ensure the air flow around the sides and back of the switch is not
restricted. Leave at least 7.6 cm (3 inches) for cooling.
■
For indoor use only. For safe and reliable operation, do not install the
switch or LAN cables outdoors.
