3com Switch 4200 28-Port. Switch type: Managed, Switch layer: L2. MAC address table: 8000 entries, Switching capacity: 12.8 Gbit/s, Maximum data transfer rate: 1 Gbit/s. Management protocols: SNMP v1. Safety: UL90950, EN60950, CSA2.2 No. 60950, IEC 60950, Certification: EN55022 Class A, FCC Part 15 Subpart B Class A,. Mean time between failures (MTBF): 451000 h

Affordable, Flexible 10/100 Switching \r\nFor 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.\r\n\r\nThis 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.\r\n\r\nResiliency 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.\r\nA true 28-port switch, with four independent Gigabit ports (two 10/100/1000, and two SFP ports)\r\n\r\n- Wirespeed, non-blocking performance\r\n- Two SFP ports, supporting all Gigabit Ethernet media, offer total connectivity flexibility.\r\n- "Right out of the box" operation for no-hassle implementation\r\n- Switch can configure its own IP settings for management through SNMP, web, or CLI.\r\n- Forwarding rates up to 9.5 million packets per second\r\n- Two built-in 10/100/1000 ports support high-speed connections as uplinks or for stacking.\r\n- IEEE 802.1x Network Login security, RADIUS Authentication and Radius Authenticated Device Access (RADA).
