PRODUCT OVERVIEW

Introduction 3Com Switch 4800G Family (hereinafter referred to as the Switch 4800G) are

Gigabit Ethernet switching products developed by Hangzhou 3Com Technologies

Co., Ltd. (hereinafter referred to as 3Com). The Switch 4800G support diversified

service features, IPv6 forwarding, and routing function, and provide 10GE

extended module slots. Through the 3Com proprietary cluster management, you

can streamline network management. The Switch 4800G are designed to operate

at the convergence or access layer of enterprise networks and metropolitan area

networks (MANs). The Switch 4800G support the IPv4/IPv6 dual stack and can also

be used for connecting server groups in data centers.

Table 2 lists the models of the Switch 4800G.

Together with an auto-sensing 10/100/1000BASE-T Ethernet port, each

1000Base-X SFP port forms a Combo port. For each Combo port, either the SFP

port or the auto-sensing 10/100/1000BASE-T Ethernet port can be used at a time.

For the mapping between the two ports forming a Combo port, refer to Table 3.
