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.
