3COM 3CR17451-91 SuperStack 3 3870 48-Ports Stackable Ethernet Switch 44 x 10/100/1000Base-T

For Enterprise Ethernet networks needing a scalable, stackable, future-proof Gigabit switching solution, the 3Com SuperStack 3 Switch 3870 is recommended. It is ideal for Gigabit to the desktop applications in high performance workgroups. As the basis for a future-proof Enterprise workgroup environment, with compatibility with slower desktop connections, it can be the platform to support a gradual move to Gigabit speeds. This 10/100/1000 Gigabit Ethernet switch combines wirespeed Layer 2 switching with stackability to up to eight units high via a 40Gbps stacking architecture for impressive scalability - to 384 ports total. The hardware supports a 10-Gigabit expansion slot and is Layer 3-capable for investment protection. The Switch 3870's auto-sensing 10/100/1000 copper ports provide flexible desktop and workgroup attachments, which can ease migration for environments with a mix of 10/100 and Gigabit-enabled desktops and servers. Four dual-purpose slots support SFPs that can connect to fiber cabling for flexible Gigabit Ethernet backbone and server connections.
