The WS-X3003 10BaseF Expansion Module
The WS-X3003 10BaseF Expansion Module
The three-port 10BaseF expansion module (WS-X3003) is used for fiber-optic connections to
computers, hubs, servers, and other high-speed network devices. The 10BaseF expansion module is
shown in Figure 8.

Inserting the 10BaseF
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 10BaseF module.
10BaseF Expansion Module Cables
The 10BaseF module's network ports are multimode fiber-optic interfaces with ST type connectors.
In full-duplex or half-duplex operating modes, the 10BaseF supports connection distances up to
2 km.
Connecting Cables to 10BaseF Expansion Module Ports
Enhanced versions of the Catalyst switch Stack support full-duplex operating mode. Unenhanced
versions of the Stack only support half-duplex operating mode. To set the half-duplex or full-duplex
mode, see Step 1 in the following cabling instructions.
Connect cables to the ST ports on the front of the 10BaseF module as follows:
Observe the following warnings and notes when cabling an expansion module with fiber-optic cable.

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 10BaseF only operate in half-duplex mode for unenhanced Catalyst switch units.
Locate the desired DUPLEX switch for the port on the front of the module, and set it 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 10BaseF cables from a hub or end-node device to the ST ports on the front of the
10BaseF expansion module.
