12-port 10/100BASE-TX Fast Ethernet MultiLayer
Switching Module
Model Number: 3CB9RF12R
The 12-port 10/100BASE-TX Fast Ethernet MultiLayer
Switching Module is a multiprotocol module designed
for the Switch 4007. The module has twelve
10/100BASE-TX Fast Ethernet front panel ports that
provide a 100 Mbps connection over UTP-Category 5
cables, and one nonblocking Gigabit Ethernet port
that connects through the backplane to the switch
fabric module. The module has two groups of six
ports, operates as a Layer 3 router switch, and
occupies a single interface module slot in the
Switch 4007 chassis.

Gigabit Ethernet Modules

The Gigabit Ethernet (GEN) Interface Modules are
two-port interface modules for the 3Com
Switch 4007. The GEN interface modules serve as a
2–Gigabit data channel between the Gigabit Ethernet
Switch Fabric Module and other 802.3z–compliant
Gigabit Ethernet devices. GEN Interface Modules use
SC connectors.
Because Gigabit Ethernet interface modules are not
intelligent, you cannot access them directly; all
communication takes place through the switch fabric
module. GEN interface modules serve as a
two-Gigabit data channel between the GEN Switch
Fabric Module and other 802.3z-compliant Ethernet
devices.
For information about how to install these modules,
see the module's Quick Start Guide that is shipped
with each module.
Gigabit Ethernet Interface Modules are available in
these port configurations:
4-port Gigabit Ethernet Interface Module
9-port 1000BASE-SX Gigabit Ethernet Layer 2
