3Com  SuperStack 3 (3CR17451-91) 44-Ports External Switch Managed stackable

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.Resiliency features such as IEEE 802.1w Rapid Spanning Tree Protocol and IEEE 802.3ad link aggregation (LACP) across stacked units help ensure uptime and availability. Enterprise-class security features include IEEE 802.1X network login, SSH/SSL encrypted device login, and access control lists.
