The Cisco Catalyst 4000 Series WS-X4448-GB-RJ45 line card extends Cisco`s leadership in the modular switched Ethernet market, providing the industry`s highest density auto-negotiating Gigabit Ethernet from the network edge directly to desktop computers. This line card provides RJ-45 ports with multispeed auto-sensing and auto-negotiating technology. This module provides wiring closet investment protection by allowing Fast Ethernet desktops today to migrate to Gigabit Ethernet in the future without replacing the switch line cards. The amount of oversubscription can be controlled by varying the number of ports. All ports can utilize Gigabit EtherChannel for high-speed interconnection applications. All ports use the standard IEEE 802.1x flow control (PAUSE frame) mechanism to control Gigabit Ethernet host traffic.
