Management LANs
— The MLANs are
high-speed management busses that provide
intermodule communication and network
connectivity to the System Management
Component (SMC). Each MLAN runs at
10 Mbps.
A power management channel informs the Switch of
the power requirements for all modules. If the EME
determines that there is not enough power in the
Switch for that module, then the module does not
power on.
The connector in the slot for the switch fabric module
is a 948-pin version of the internetworking connector.
This connector supports connections up to
30 high-speed, full-duplex, serial links on the
backplane and all the other chassis services that are
available to the switch fabric module.
Interface modules and the switch fabric module
access Switch services through connectors to the
backplane.

Power Supplies
The CoreBuilder 9000 7-slot chassis can contain two
back-loading, 930-watt, modular AC power supplies
(Model Number 3CB9EP9) or two –48-volt DC power
supplies (Model Number 3CB9EP8D7). The power
supplies provide power to the management modules,
switch fabric module, interface modules, fans, and
backplane.
Figure 3 shows a 930-watt AC power supply in a
CoreBuilder 9000 7-slot chassis.
