Power supplies
Hot-plug power supplies are not designed to be removed or installed with AC power connected
to the power supply. To reduce the risk of electric shock or damage to the equipment when

to the power supply. To reduce the risk of electric shock or damage to the equipment when
handling hot-plug power supplies:
•
Install the power supply before connecting the power cord to the power supply.
•
Unplug the power cord before removing the power supply from the product.

If the system has multiple sources of power, you must unplug all AC power cords from the
power supplies to completely disconnect power from the system.
power supplies to completely disconnect power from the system.
•
DC input power supplies do not connect directly to external bulk-level power systems
(48/60Vdc battery power). They must be connected to a local power distribution unit (PDU)
that provides a dedicated output with suitable overcurrent protection for each power
supply. The overcurrent protection (circuit breaker/pluggable fuse module) must be sized
according to the input rating of each power supply. Refer to the documentation provided
with the DC-powered system.
