If you only have one Switch Fabric Management Module (SFMM) installed and
you remove it or it fails, all traffic on the interface modules will be interrupted.

If your chassis is already operating in your network and you want to remove the
primary SFMM, first ensure that a secondary (standby) SFMM resides in the
chassis. When you remove the primary module, the secondary module is
activated and the system is automatically reset.

CAUTION: Do not install or remove modules during the system power-on process
or while software is downloading to the Switch Fabric Management Module.

You do not need to disconnect power before you install modules in the Switch
4005 chassis. You can install modules while the chassis is operating. This action
is called a hot swap. See the section “Hot Swap” earlier in this chapter for
more information.

■
The SFMM stores configuration information for up to twelve interface
modules. This information is associated with a module’s hardware addresses
which are preprogrammed at the manufacturing center, i.e., every module has
unique port-based hardware addresses called MAC addresses. When you
remove a module and insert a new module in that slot — even one of the same
type — you cannot transfer the old module’s configuration to this module. You
will have to manually configure the parameters for the new module’s ports.
However, if you immediately re-installed the original module in that slot or in a
different slot, the chassis would “remember” the module and retain its
configuration parameters.

If a module fails and you need to replace it with another one of the same type,
you must configure the new module manually. At this time, you cannot
download the previous module’s configuration to the new module.

CAUTION: Be sure to follow the module removal procedure in this chapter. This
procedure includes pressing the Release Button on the module and waiting until
the Release LED stops flashing before you unscrew the module, release the ejector
handles, and remove the module.

If you are performing the initial installation of a Switch 4005, 3Com
recommends that you install all modules and power supplies first, then power
up the Switch. This way, you can direct your full attention to the LEDs on the
modules and power supplies. If the Switch is powered up when you install
components, you must finish securing them before you can concentrate on the
LEDs.

■
After you install a new module, you must access the CLI or Web interface to
configure the module’s ports as members of VLANs, include them in
aggregated links, and so forth. See the Switch 4005 Software Configuration
Guide.
