Power precautions

CAUTION
Use a separate branch circuit for each AC power cord, which provides redundancy in case one of
the circuits fails.
CAUTION
Ensure that the device does not overload the power circuits, wiring, and over-current protection.
To determine the possibility of overloading the supply circuits, add the ampere (amp) ratings of all
devices installed on the same circuit as the device. Compare this total with the rating limit for the
circuit. The maximum ampere ratings are usually printed on the devices near the input power
connectors.
CAUTION
Make sure you insert the power supply right-side up. It is possible to insert the supply upside
down, although the supply will not engage with the power backplane when upside down. The
power supply is right-side up when the manufacturer label is on the top.
CAUTION
Remove the power cord from a power supply before you install it in or remove it from the device.
Otherwise, the power supply or the device could be damaged as a result. (The device can be
running while a power supply is being installed or removed, but the power supply itself should not
be connected to a power source.)
