Introduction

For copper-wired Ethernet networks that need premium switching performance and the flexibility of Fiber or Copper Gigabit uplinks (via fixed 10/100/1000 or GBIC ports) without the complexity and high price, the 3Com® SuperStack® 3 Switch 4228G is an innovative, yet very practical solution.

This 28-port Ethernet switch combines wirespeed Layer 2 switching with easy installation and exceptional reliability, backed by 3Com's limited lifetime warranty. Twenty-four autosensing 10/100 copper ports provide flexible desktop and workgroup attachments, while two autosensing 10/100/1000 copper uplink ports support stacking or Gigabit connections, and two flexible GBIC expansion slots enable an additional choice of fiber or copper Gigabit Ethernet backbone and server connections.

Resiliency features such as Rapid Spanning Tree Protocol, link aggregation (for the 10/100/1000 ports), and a redundant power option help ensure uptime. Built-in Gigabit ports can be used as uplinks or for stacking with a mix of other SuperStack 3 Switch 4228G, or with SuperStack 3 Switch 4250T and Switch 4226T units. Up to four units can be stacked for maximum scalability.
