14 CHAPTER 1: INTRODUCING THE SWITCH 4200G FAMILYAbout the Switch4200GThe Switch 4200G Family products include mixed media devices thatconsist 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 onthe Switch 4200G 12-Port unit. This requires an optional XFP.■ Two optional module slots for a 10 Gigabit Ethernet port module onthe Switch 4200G 24-Port and 48-Port units. This requires an optionalXFP.■ One RJ-45 connector for serial managementThe Switch 4200G Family provides high-performance workgroups with abackbone-to-server connection.The Switch 4200G PWR 24-Port providessimilar Ethernet functionality to other family models with the addedbenefit 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 inPDF format on 3Com’s Web site at www.3com.com.Summary ofHardware FeaturesTable 2 summarizes the Switch 4200G’s hardware features.Table 2 Hardware FeaturesFeature Switch 4200GAddresses Up to 8,000 supportedAuto-negotiation Supported on all portsForwarding Modes Store and ForwardDuplex Modes Half and full duplex on all front panel portsAuto MDI/MDIX Supported on all ports.
