Overview
The Catalyst 2900 series XL modules add port density and high-performance
connectivity to a Catalyst 2900 series network. When installed in the appropriate
Catalyst 2900 series switch, these modules support a full range of cabling types,
port connectors, and 10, 100, and 1000 megabit-per-second (Mbps) transmission
speeds. All the Catalyst 2900 series modules autonegotiate the duplex mode of
each port to match that of the attached device. The Ethernet and Fast Ethernet
modules also autonegotiate the speed settings of each port.
This chapter contains the following topics:
•Key features of the modules
•Descriptions of the module LEDs
•Module cabling guidelines
•Examples of how the modules can be deployed
The Catalyst 2900 series modules support Inter-Switch Link (ISL) and IEEE
802.1Q trunking or multi-virtual LAN (VLAN) ports. The following table
describes the modules by model number.

Figure 1-1 10/100 Module
The 10/100 module is compatible with the IEEE 802.3 10BaseT standard and the
IEEE 802.3u 100BaseT standard. The ports use RJ-45 connectors and Category 5
unshielded twisted-pair (UTP) copper cabling. For connector and schematic
information, see Appendix B, “Connectors and Cables.”
100BaseFX Modules
The 100BaseFX modules have either two or four switched 100BaseFX ports for
100-Mbps fiber-optic connectivity. The ports can run in half-duplex or full-duplex
modes. The module support the IEEE 802.3u 100BaseT standard and use
standard, duplex, SC connectors. Figure 1-2 and Figure 1-3 show the 100BaseFX
modules.
