Power Supplies

The Switch 4007R 8-slot chassis contains an
820-watt, modular AC power supply (Model Number
3CB9EP8). The power supply provides power to the
management modules, switch fabric modules,
interface modules, fans, and backplane.
You can add or replace power supplies while the
chassis is running (referred to as warm swapping).
Switch 4007R power supplies are autosensing. Each
power supply (Figure 10) 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 820-watt power supply (Figure 3) has its own
power cord and is shipped separately from the
chassis. The type of power cord depends on your
country location.
