Installation Precautions - HP ProCurve 420 Installation And Getting Started Manual

Installation Precautions:

Follow these precautions when installing your HP Access Point 420ww/na.
C a u t i o n s
Make sure that the power source circuits are properly grounded, then use
the power adapter supplied with the access point to connect it to the
power source.
You can alternatively power the access point through a network connec-
tion to a switch or other network connection device that provides Power
over Ethernet. However, note that if the access point is connected to a
power source, Power over Ethernet will be disabled.
Use only the AC power adapter supplied with the access point. Use of
other adapters, including adapters that came with other HP network
products, may result in damage to the equipment.
When installing the access point, note that the AC outlet should be near
the access point and should be easily accessible in case the access point
must be powered off.
Ensure that the access point 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 access point 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 access point in an environment where the operating
ambient temperature might exceed 55°C (131°F).
Make sure the air flow around the sides of the access point is not
restricted.
