Installing the Power Supply

Installation Cautions:

Make sure the power source circuits are properly grounded, then use the power cord
supplied with the power supply to connect it to the power source.
If your installation requires a different power cord than the one supplied with the power supply,
be sure 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 power supply.
When installing the switch, note that the AC outlet should be near the switch and should be
easily accessible in case the switch must be powered off.
Ensure the power supply 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 with this power
supply and compare the total with the rating limit for the circuit. The maximum ampere
ratings are usually printed on the devices near their AC power connectors.
Do not install the power supply into a switch that is in an environment where the operating
ambient temperature might exceed 55°C (131°F)
8200zl chassis, the ambient temperature must not exceed 40°C (104°F).
Make sure the air flow around the sides and back of the switch is not restricted.
Make sure that for any switch power supply slot into which a power supply is not installed,
the cover plate is installed to cover the slot. A cover plate is required for safe operation,
and to ensure proper switch cooling.
The switch power supplies are hot swappable; they can be installed or removed while the switch
is receiving power from the supply in the other slot. But, as indicated by the caution statement
on the power supply, the supply must not be connected to AC power before being installed
or removed.
