Power Supplies
The CoreBuilder 9000 8-slot chassis can contain three
front-loading, 820-watt, modular AC power supplies
(Model Number 3CB9EP8) or three –48-volt DC
power supplies (Model Number 3CB9EP8D). The
power supplies provide 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). See
Chapter 8 "Maintenance for the 8-Slot Chassis and
16-Slot Chassis" for instructions about how to
replace a faulty power supply.

820-watt AC Power Supply

CoreBuilder 9000 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 10) has its own
power cord and is shipped separately from the
chassis. The type of power cord depends on your
country location.
