Management Module
Overview
The Switch 4005 is required to have one Switch Fabric Management Module
(SFMM) installed in slot M1 or M2. These slots can only house this type of module.
(SFMM) installed in slot M1 or M2. These slots can only house this type of module.
CAUTION: All standard chassis and starter kit chassis leave the manufacturing
center with one SFMM preinstalled in slot M1 or M2. The other M slot will be
covered with a blank faceplate and you must leave it in place until you are ready to
install a redundant SFMM.

install a redundant SFMM.
The SFMM performs two critical functions in the chassis: (1) the central switch
fabric and (2) the management entity.
fabric and (2) the management entity.
Switch Fabric Functions
The Switch Fabric Management Module includes a switch fabric that serves as the
central backplane aggregator for the chassis. That is, if an interface module
receives a packet that is not destined for one of its local ports, it forwards it to the
SFMM for processing. The SFMM routes the packet to the correct interface
module in the chassis.

module in the chassis.
The system software resides on the SFMM. Software is preinstalled on the SFMM
at the manufacturing center so that the Switch is ready to operate in your network
after you physically install it. For information about the default settings on the
software features or how to modify them see the Switch 4005 Software
Configuration Guide.

Management Functions
The Switch Fabric Management Module exchanges information with all modules
through the management bus. The module uses the management bus to send
commands to interface modules and to collect information from interface
modules.

The Switch 4005 software includes a Web management interface and a
menu-based command line interface. You can access the Web management
interface through any Ethernet port from your PC using a Web browser. You can
access the command-line interface through the RS-232 console port on the SFMM
by using terminal emulation software (such as HyperTerminal for Windows

The SFMM also allows you to configure and monitor the Switch 4005 chassis
