Novinka, náhrada oblíbeného modelu 3C17304-ME (SS3 Switche 4228G) Features, Benefits & Specifications Affordable, Flexible 10/100 Switching 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 SFP ports) without the complexity and high price, the 3Com® Switch 4200 28 Port is an innovative, yet very practical solution. This 28-port Ethernet switch combines wirespeed Layer 2 switching with easy installation and exceptional reliability. 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 SFP expansion slots enable an additional choice of fiber or copper Gigabit Ethernet backbone and server connections. Resiliency features such as Rapid Spanning Tree Protocol and link aggregation (for the 10/100/1000 ports) help ensure uptime. Built-in Gigabit ports can be used as uplinks or for stacking with a mix of other Switch 28-, 26- or 50-Port units. Up to four units can be stacked for maximum scalability.
