The WS-X3005 100BaseF Expansion Module
The 100BaseF expansion module (WS-X3005) is a single-port 100BaseFx expansion module used
for high-bandwidth fiber-optic connections to computers, hubs, servers, and other high-speed
network devices. The 100BaseF expansion module is shown in Figure 9.

Inserting the 100BaseF Module
Expansion modules are installed in the expansion slots on the front of the Catalyst switch. All front
expansion modules are installed in a similar way. Use the previous section "Installing The
WS-X3001 (100Base TX) Expansion Module" as an example for detailed installation instructions
and precautions for the 100BaseF module.
100BaseF Expansion Module Cables
The 100BaseF module's network port has 1300 nm multimode fiber-optic ST type connectors.
In full-duplex operating mode, the 100BaseF supports connection distances up to 2 km. In
half-duplex operating mode, the 100BaseF supports connection distances up to 400 meters.
Connecting Cables to 100BaseF Expansion Module Ports
Enhanced versions of the Catalyst switch support half- or full-duplex operating mode, while the
unenhanced version supports only half-duplex mode. If the Catalyst switch in which the 100BaseF
is being installed is an enhanced version, refer to the section "Configuring Full-Duplex
Communications" in the Catalyst Stack Installation and Configuration Guide. That section provides
details about half-duplex or full-duplex communication mode.
Connect cables to the ST ports on the front of the 100BaseF module as follows:
Observe the following warnings and notes when cabling an expansion module with fiber-optic cable.

DIAG
1
Laser radiation is present when the system is open.
Do not stare into the laser beam.
Determine if the unit is operating in half-duplex or full-duplex mode. The Catalyst switch
and the 100BaseF operate only in half-duplex mode for unenhanced Catalyst switch units.
Set the DUPLEX switch on the front of the module to the appropriate position: down for
half-duplex, or up for full-duplex. Set to half-duplex for unenhanced Catalyst switch units.
Determine that you have the correct cable.
Connect a 100BaseFx cable from an end-node device to the ST ports on the front of the
expansion module.
