Installing Catalyst Switch Front Expansion Modules
The 10BaseT Expansion Module
The four-port 10BaseT expansion module (WS-X3002) is used for connections to computers, hubs,
servers, and other network devices. The 10BaseT module is shown in Figure 6.

Inserting the 10BaseT
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 10BaseT module.
10BaseT Expansion Module Cables
The 10BaseT module's network ports are RJ-45 connectors that use 10BaseT cable.
Note
place of the other may cause system performance problems. 10BaseT is a Category 3 cable, and
100BaseTX is a Category 5 cable (physically, Category 5 cable is usually a little heavier or stiffer
than Category 3 cable). Check to see if the cable type is printed on the cable jacket.
The 10BaseT module's network ports are RJ-45, 10BaseT types that are always in MDI-X mode.
Cabling the 10BaseT to different types of equipment that have MDI or MDI-X ports requires
different types of 10BaseT cable. The cable types are described below.

10BaseT and 100BaseTX cable have the same connectors and cable pinouts, but using one in
Straight-through cable: If the 10BaseT is cabled to a port that is MDI, such as a server, use a
straight-through connecting cable.
Crossover cable: If the 10BaseT is cabled to a port that is also MDI-X, such as a high-speed hub,
use a crossover cable.
