12CHAPTER 1: INTRODUCING THE SUPERSTACK 3 SWITCH 4900 SERIES

About the Switches ■ The Switch 4900 connects your existing 100 Mbps devices and high-performance workgroups with a 1000 Mbps copper backbone or server connection.

■The Switch 4900 SX connects your existing 1000 Mbps devices and high-performance workgroups with a 1000BASE-SX fiber backbone or server connection.

■The Switch 4924 connects your existing 10 Mbps and 100 Mbps devices and high-performance workgroups to a 1000 Mbps copper backbone or server connection.

■The Switch 4950 is a 10/100/1000 Mbps mixed media device that allows you to connect your existing 10/100/1000 Mbps devices and high-performance workgroups to a fiber or copper gigabit backbone or server connection.

You can also interconnect any combination of two Switches from the SuperStack® 4900 Series or 3Com Switch 4050/4060 range to create an XRN Distributed Fabric. This allows you to create a highly resilient core around which you can build your network. For more information about interconnecting Switches, see “Creating an XRN Distributed Fabric” on page 24. For more information about 3Com XRN Technology and how to use it in your network, refer to the Implementation Guide on the CD-ROM that accompanies the Switch.

For information about using the software features of the Switch, refer to the “SuperStack 3 Switch Management Interface Reference Guide” on the CD-ROM that accompanies the Switch.
