3COM SWITCH 4210G

GIGABIT FAMILY

From top: 3Com Switch 4210G PWR 24-Port,

Switch 4210G 24-Port, Switch 4210G 48-Port

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.

2 3COM SWITCH 4210G GIGABIT FAMILY

KEY BENEFITS

(continued)

The PWR model with available Power over Ethernet readies your network for running converged applications such as voice, wireless and video surveillance over the network.

ENHANCES MANAGEMENT AND CONTROL

The Switch 4210G family is easy to use and manage, designed to increase business productivity by reliably supporting business applications. Cluster together up to 255 devices for easy administration, with single IP management across 3Com switching lines.

Models with 10-Gigabit expansion ports can be stacked together up to four high, with robust features from 3Com's IRF stacking technology including distributed link aggregation.

GIVES FLEXIBLE, BASIC LAYER 3 ROUTING

Layer 3 static routing, with 32 definable static routes, gives this switch added flexibility to handle more complex networking needs.

REDUNDANT POWER SYSTEM SUPPORT

The 3Com Switch 4210G models support a redundant power system (RPS) connection.

For this model, the RPS unit delivers redundant power to switches so there is continued operation should the switch unit power supply fail. This allows for continuous operation of advanced Enterprise networks, particularly important for converged networks running IP phones on the network.

3Com H3C RPS Systems

3Com switches are compatible with 3Com H3C ® RPS solutions. These are enterprise-class power redundancy systems that work with many 3Com fixedconfiguration switches. 3Com Corporation manufactures networking equipment under the H3C brand for sale into many markets.

The H3C RPS 1000 is 1U high and provides multiple power output connections to support multiple switch units at the same time. Two power rectifiers can be installed for 1+1 load sharing and power redundancy.

It supports switches with -54V RPS connections, and delivers sufficient power to fully provision all PoE ports of a switch with full power redundancy.

SUPPORTED BY LIMITED LIFETIME HARDWARE

WARRANTY

3Com gives a Limited Lifetime Hardware Warranty on the Switch 4210G Gigabit Family. Also provided is

Advanced Hardware Replacement, with next business day shipment available in most regions, and telephone support and limited lifetime software updates.
