Installation Precautions - HP ProCurve 224 Installation Manual

Installation Precautions:

Follow these precautions when installing your HP Switch 212M or
Switch 224M.
W a r n i n g
The rack or cabinet should be adequately secured to prevent it from
becoming unstable and/or falling over.
Devices installed in a rack or cabinet should be mounted as low as
possible, with the heaviest device at the bottom and progressively
lighter devices installed above.
C a u t i o n s
Make sure that the power source circuits are properly grounded,
then use the power cord supplied with the switch to connect it to the
power source.
If your installation requires a different power cord than the one
supplied with the switch, 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.
Ensure that 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. The 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 55 C (131 F).
Make sure the air flow around the sides and back of the switch is
not restricted.
Make sure that if no module is installed in the module slot, the cover
plate is installed to cover the slot. A cover plate is required for safe
operation, and to ensure proper switch cooling.
