Stackable Managed Gigabit Switching

For Enterprise Ethernet networks needing a scalable, stackable, future-proof Gigabit switching solution, the 3Com® SuperStack® 3 Switch 3870 48-Port is recommended.

This 48-port 10/100/1000 Gigabit Ethernet switch combines wirespeed Layer 3 switching with stackability 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.

Forty-eight 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 helps ensure uptime and availability. Enterprise-class security features include IEEE 802.1X network login, SSH/SSL encrypted device log-in, and access control lists.

Features:
48 auto-negotiating 10/100/1000 ports for seamless migration from Ethernet or Fast Ethernet to Gigabit Ethernet

Integrated dual 10Gbps full duplex stacking ports— 40Gbps total stacking bandwidth— for stacking of up to eight units high

Wirespeed, with forwarding rates up to 115 million pps, and a switching capacity of 156Gbps

Includes four dual-purpose ports, supporting SFP slots to accommodate 1000BASE-SX, 1000BASE-LX, and 1000BASE-LH connectivity

Up to 32 trunks of eight ports each can be configured using IEEE 802.3ad LACP, delivering 8Gbps bandwidth uplinks per trunk; trunked ports able to cross stacked units

Quality of Service (QoS), with eight queues per port, control traffic flow and improve network performance

Utilize 254 VLANs to control and secure network traffic

3Com Network Supervisor software (60-day trial version included) supports automatic prioritization of real-time or critical traffic
