930-Watt Ac Power Supply; 48-Volt Dc Power Supply - 3Com 3CB9E7 - CoreBuilder 9000 Chassis Switch Getting Started Manual

You can add or replace power supplies while the
chassis is running (referred to as warm swapping). See
Chapter 7, "Maintenance for the 7-Slot Chassis," for
instructions about how to replace a faulty power
supply.

930-watt AC Power Supply

CoreBuilder 9000 power supplies are autosensing.
Each power supply (Figure 3) can automatically sense
the type of input voltage to which it is being
connected at the electrical outlet.
The power supplies are load sharing in that all power
supplies provide an equal amount of the load current.
Each 930-watt power supply has its own power cord
and is shipped separately from the chassis. The type
of power cord depends on your country location.
