Fast Ethernet Modules
The frame-based switching modules are intelligent
Layer 2 and Layer 3 modules that have their own
embedded agent. These modules are physically
connected to the backplane ports of the switch fabric
module in the chassis. These modules switch between
the front panel ports and the backplane ports.
Switching interface modules provide network
connectivity functions.
Fast Ethernet Interface Modules are available in these
port configurations:
■
20-port 100BASE-FX (MT-RJ) Fast Ethernet Layer 2
Switching Module
■
36-port 10/100BASE-TX Fast Ethernet RJ-45 Layer
2 Switching Module
■
12-port 10/100BASE-TX Fast Ethernet MultiLayer
Switching Module
20-port 100BASE-FX (MT-RJ) Fast Ethernet Layer 2
Switching Module
Model Number: 3CB9LF20MM
The 100BASE-FX (MT-RJ) Fast Ethernet Layer 2
Switching Module has twenty 100 Mbps Ethernet
fiber-optic ports with MT-RJ connectors on its front
panel and two 1-Gigabit ports for connection to the
chassis backplane. It operates as a Layer 2 switch and
occupies a single interface module slot in the
Switch 4007 chassis.
Figure 9 identifies the components on the front panel
of the module. The front panel ports on the module
are numbered 1 through 20. The two 1-Gigabit ports
on the back of the module are numbered 21 and 22.

CD-ROM.
36-port 10/100BASE-TX Fast Ethernet RJ-45 Layer 2
Switching Module
Model Number: 3CB9LF36R
The 10/100BASE-TX Fast Ethernet RJ-45 Layer 2
Switching Module (36-port FEN RJ-45 Switching
Module) has thirty-six 10/100 Mbps Ethernet ports
with RJ-45 connectors on its front panel, and two
1-Gigabit ports on the back for connection to the
chassis backplane. It operates as a Layer 2 switch and
occupies a single interface module slot in the
Switch 4007 chassis.
