Power Availability and Power Supply Capacity

This section explains the following concepts
concerning power supply management:
Power available to modules — The amount of
power that is available to CoreBuilder 9000
modules is determined by the number of power
supplies that are installed.
Power capacity of a power supply — The
power capacity of a power supply unit is the
maximum amount of power that the power supply
delivers.
When you manage power in your Switch, consider
the system overhead, that is, the power that the
Switch itself (including fans, signalling, and EMEs)
consumes. Before you install any new module into a
chassis, assess the power budget by calculating the
total power requirements for all installed modules,
fans, and management modules.
See the documentation that is supplied with each
module to determine your module power
requirements. Take into account any modules that
you plan to install, as well as those that are already
installed.
For information about how to manage power in your
Switch, see Chapter 5, "Configuring the Chassis
Using Management Commands" in the
CoreBuilder 9000 Enterprise Management Engine
User Guide that is on the Documentation CD-ROM.
