SWITCHING
DATA HEET
OVERVIEW
The 3Com®Switch 4200G Gigabit amily 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. or great flexibility, four of the ports are
dual-personality, operating either as 10/100/1000 or
S P-based fiber. These switches accommodate one or
two extra 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 switches come with a limited
lifetime warranty and next business day, advanced
hardware replacement in most regions.
amily switch models—clusterable in any combination
up to 32 units—are:

KEY BENEFIT
AFFORDABLE MANAGED GIGABIT CONNECTIVITY
The Switch 4200G family is 3Com’s most economical
Gigabit 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 4200G 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.
Switch 4200G models support 10-Gigabit uplinks to tie
into an evolving core network infrastructure. They are
XENPAK transceiver ready, requiring no additional
module for 10-Gigabit XENPAK support. A module for
10-Gigabit X P support is also available.

EMPOWER APPLICATION CONVERGENCE
The Switch 4200G 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.
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.
ENHANCE MANAGEMENT AND CONTROL
The Switch 4200G family is easy to use and manage,
designed to increase business productivity by reliably
supporting business applications. Cluster together up
to 32 devices for easy administration, with single IP
management across 3Com switching lines.
DELIVER HIGH PERFORMANCE
No need to buy new switches when additional network
performance is needed, as the Switch 4200G family
features 12-, 24- and 48-port models, providing
aggregate switching capacity up to 136 Gbps and
101.2 Mpps performance on the 48-port model.
GIVE FLEXIBLE, BA IC 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 Y TEM UPPORT
The 3Com Switch 4200G PWR model supports a
redundant power system (RPS) connection.
or 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 fixed-
configuration 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.
UPPORTED BY LIMITED LIFETIME HARDWARE
WARRANTY
3Com gives a Limited Lifetime Hardware Warranty on
the Switch 4200G Gigabit amily. Also provided is
Advanced Hardware Replacement, with next business
day shipment available in most regions, and telephone
support and limited lifetime software updates.
