14CHAPTER 1: INTRODUCING THE SWITCH 4200G FAMILY

About the Switch 4200G

The Switch 4200G Family are mixed media devices which consist of:

■12, 24 or 48 10/100/1000BASE-T ports

■Four 1000BASE-X SFP ports

■One option module slot for a 10 Gigabit Ethernet port module on the Switch 4200G 12-Port. Requires an optional XFP.

■Two option module slots for a 10 Gigabit Ethernet port module on the Switch 4200G 24-Port and the Switch 4200G 48-Port. Requires an optional XFP.

■One RJ-45 connector for serial management

The Switch 4200G Family provides high-performance workgroups with a backbone to server connection. You can also add the Switch 4200G Family to any SuperStack® system as your network grows.

For information about using the software features of the Switch, refer to the “Command Reference Guide” and the “Configuration Guide” on the CD-ROM that accompanies the Switch.
