OVERVIEW
The 3Com
®
Switch 4210G Gigabit Family delivers
quad-speed performance—10/100/1000 and 10-
Gigabit–with plug-and-play "Gigabit-to-the-Desktop"
switching and rich, easy-to-use features perfect for
cost-conscious medium-sized businesses wanting a
fast, efficient network upgrade.
Layer 2 switching along with Layer 3 static routes
make these ideal for wiring closet, workgroup
connectivity. For great flexibility, four of the ports are
dual-personality, operating either as 10/100/1000 or
SFP-based fiber. Specific models support up to four
optional 10-Gigabit high-speed links, enabling
connectivity to a core network or to high
performance servers.
Enterprise-class security features include IEEE 802.1X
network login, SSL encrypted device log-in and Access
Control Lists.
These are the family switch models:
> 3Com Switch 4210G 24-Port:
24 auto-negotiating 10BASE-T/100BASE-TX/
1000BASE-T ports, four of which are
dual-personality 10/100/1000 or 100/1000 SFP;
two expansion slots for up to four 10-Gigabit ports.
> 3Com Switch 4210G 48-Port:
48 auto-negotiating 10BASE-T/100BASE-TX/
1000BASE-T ports, four of which are
dual-personality 10/100/1000 or 100/1000 SFP;
two expansion slots for up to four 10-Gigabit ports.
> 3Com Switch 4210G PWR 24-Port:
24 auto-negotiating 10BASE-T/100BASE-TX/
1000BASE-T ports, four of which are
dual-personality 10/100/1000 or 100/1000 SFP;
Power over Ethernet on all 10/100/1000 ports;
two expansion slots for up to four 10-Gigabit ports.
KEY BENEFITS
AFFORDABLE MANAGED GIGABIT CONNECTIVITY
The Switch 4210G family is 3Com’s most economical
Gigabit fully managed stackable switch line. Achieve
up to a 10-times performance improvement with
Gigabit, at prices many still associate with 10/100
switches.
FUTURE PROOF NETWORKING
3Com Switch 4210G switches provide outstanding
investment protection by providing quad-speed
10/100/1000 Mbps and 10-Gigabit switching.
Gradually move users to Gigabit speeds, with full
backward compatibility with slower 100 Mbps and
10 Mbps networking.
Select Switch 4210G models support 10-Gigabit
uplinks using "4500G-style" uplink modules.
EMPOWERS APPLICATION CONVERGENCE
The Switch 4210G family combines high performance
Gigabit switching, QoS and traffic management
features to help ensure essential applications get the
appropriate priority for efficient utilization of network
resources.
