Genuine Original Cisco Catalyst 2900 Series 2912 XL 12-Port 10/100 Fast Ethernet Switch FAB0523W2J3 WS-C2912-XL-EN. The Cisco Catalyst 2912 XL switch has 12 10BASE-T/100BASE-TX switched ports, the Catalyst 2924 XL has 24 10BASE-T/ 100BASE-TX ports, and the Catalyst 2924C XL has 22 10BASE-T/100BASE-TX ports and two 100BASE-FX ports. These switches are members of the Catalyst 2900 series XL family and each of them is very easy to deploy, either on a desktop or mounted in a wiring closet within its on-rack-unit-high enclosure.

Part Number: WS-C2912-XL-EN
Compatible Numbers: FAB0523W2J3

Features:

• 12 or 24 10BASE-T/100BASE-TX autosensing ports deliver performance where it is needed most—to demanding workgroups and servers—while preserving legacy 10BASE-T connectivity (Catalyst 2912 XL and Catalyst 2924 XL).
• Twenty-two 10BASE-T/100BASE-TX autosensing ports deliver performance where it is needed most—to demanding workgroups and servers—while preserving legacy 10BASE-T connectivity. Two 100BASE-FX ports deliver up to 200 Mbps of bandwidth over an extended distance of up to 2 kilometers (Catalyst 2924C XL).
• A 3.2-Gbps switching fabric and 3.0-million-pps forwarding rate ensure optimal performance on all 10BASE-T/100BASE-TX ports.
• Full-duplex operation on switched 100BASE-T ports delivers up to 200 Mbps of bandwidth to end stations, servers, and between switches.
• A 4-MB shared-memory architecture ensures the highest possible throughput by eliminating head-of-line blocking, minimizing packet loss, and reducing congestion from multicast and broadcast traffic.
• Bandwidth aggregation through Fast EtherChannel technology enhances fault tolerance and offers up to 800 Mbps of bandwidth among switches, routers, and individual servers.
• Up to 12 Fast EtherChannel bandwidth aggregation groups per switch allow each Catalyst 2900 XL switch to aggregate multiple network devices via standard, full-duplex 10/100 Fast EtherChannel links.
