14 CHAPTER 1: INTRODUCING THE SWITCH 4200G FAMILY
About the Switch
4200G
The Switch 4200G Family products include mixed media devices that
consist of:
■ 12, 24, or 48 10/100/1000BASE-T ports
■ Four 1000BASE-X SFP ports
■ One optional module slot for a 10 Gigabit Ethernet port module on
the Switch 4200G 12-Port unit. This requires an optional XFP.
■ Two optional module slots for a 10 Gigabit Ethernet port module on
the Switch 4200G 24-Port and 48-Port units. This 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.The Switch 4200G PWR 24-Port provides
similar Ethernet functionality to other family models with the added
benefit of IEEE 802.3af Power over Ethernet.
For information about using the switch’s software features, refer to the
“Command Reference Guide” and the “Configuration Guide” available in
PDF format on 3Com’s Web site at www.3com.com.
