CAUTION:
Use a separate branch circuit for each 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:
The power supply switch must be in the off position when you insert the power supply
into the chassis. Damage to the switch can result if a live power supply is installed.
CAUTION:
Carefully follow the mechanical guides on each side of the power supply slot and make
sure the power supply is properly inserted in the guides. Never insert the power supply
upside down.
Note: Device control processors and management modules may contain batteries for RTC or NVRAM
backup. Dispose of components containing batteries as required by local ordinances and regulations.
