1 Product Overview
Overview
3Com Switch 4210G Family (hereinafter referred to as the Switch 4210G ) are Layer 3 Gigabit Ethernet
switching products developed by 3Com Corporation. (Hereinafter referred to as 3Com).
The Switch 4210G are designed as distribution or access devices for intranets and metropolitan area
networks (MANs). Supporting IPv4/IPv6 dual stack, the Switch 4210G provide abundant service
features.
The Switch 4210G include six models, and have the system specifications as shown in
all support the 3Com-specific cluster management function, which facilitates your network management.
And four models of the Switch 4210G also support 10 GE uplink interfaces and the Intelligent Resilient
Framework (IRF) technology. You can connect multiple 4210G switches through 10 GE ports to form a
logical entity, thus to establish a new intelligent network with high reliability, expandability and
manageability.

1000Base-X SFP Port
The SFP ports on the front panel of Switch 4210G supports fiber Gigabit Ethernet long-wave (LX),
long-haul (LH70) and copper (T) transceivers in any combination..
All SFP transceivers are hot swappable and optional. Therefore, networking is more flexible.
z You are recommended to use SFP transceivers of 3Com on the Switch 4210G.
z The types of SFP transceivers may update with time. For information about transceivers, contact
3Com technical support or marketing staff.

Combo Port
One SFP port and the corresponding 10/100/1000Base-T Ethernet port form a Combo port. For each
Combo port, either the SFP port or the corresponding 10/100/1000Base-T Ethernet port can be used at
a time. For details about the combo port mapping relationship, please refer to
Table 1-4 Combo port mapping relationship
