SWITCHES

10/100 Mbps switches for small and medium
businesses needing basic connectivity

OPTIMAL NETWORK CONNECTIVITY

Auto-speed sensing 10/100/ Mbps connectivity. Enables
connection at 10 and 100 Mbps, ensuring optimum throughput
for applications and compatibility with legacy equipment.

Full-duplex support of your network. Allows full two-way
data transfer, doubling the effective bandwidth.

FCC Class B certified. Certified for home and office use
(more stringent than Class A certification).

EASY TO USE

Auto MDI/MDIX on every port. Eliminates most common
cabling problems, whether the port is connected to a server,
PC, another switch or hub.

Front panel LEDs. Provides immediate notification of network
use—port speed/activity—without requiring special technical
knowledge.

Operating system independence. Supports maximum
integration of different operating systems within a network—
no extra configuration of the network is required.

Plug-and-Play convenience. For hassle-free installation and
simple set-up, no complicated configuration is required.

Silent operation. Self-cooling fanless design ensures there is
no noise disturbance from the switches.

OVERVIEW

3Com®OfficeConnect®Fast Ethernet Switches are designed for small offices requiring high
network performance to exchange large data files and images and access real-time information.

These reliable and dependable switches automatically find the fastest connection speed; all that is
needed is to connect the power and Ethernet cables, as there is no software to configure. Easy to set
up, these switches feature a fan-less design which delivers silent operation, and are backed by an
outstanding three-year limited warranty. Advanced hardware replacement is also provided.

With a choice of five, eight or sixteen ports you can easily expand your network by adding more
computers or devices with speeds up to 200 Mbps per port in full-duplex mode. As part of our
GreenConnect initiative, this switch has been designed to have a very small form-factor, reducing
the environmental impact from this product.
