Key Benefits

Wide-Ranging Unmanaged Family

Plug-and-Play Unmanaged Operation

Small to mid-sized businesses looking for
a switched LAN with or without highspeed uplinks, or a low cost,
high-performance Gigabit network, will
find an affordable solution with the family
of 3Com® Baseline switches, designed for
plug-and-play network operation.

3Com Baseline switches operate straight
out of the box, with no configuration
required. Auto MDI/MDIX ports identify
and adapt to the Ethernet cable type,
eliminating the most common cabling
errors and simplifying installation.
Autosensing ports detect and adjust to the
speed of the connected device to optimize
network performance.

10/100 Switching with Legacy Support

3Com Baseline Switch 2016 and 2024 are
ideal for businesses with legacy Ethernet
desktops that want to start a network.
Fast Ethernet (100 Mbps) support easily
handles higher speed desktop and office
server connections.
10/100 Switching, Gigabit Uplinks

For businesses ready to step up their
network performance, the 3Com Baseline
Switch 2226 and 2250 offer 10/100
switching with two high-speed dual
purpose ports that can be used either as
10/100/1000 for fixed copper connections,
or fiber connections utilizing two Gigabit
SFP (Small Form-Factor Plug-in or miniGBIC) transceiver slots that accommodate
any standard 1000BASE-LX or -SX transceiver module.
High-Performance 10/100/1000
Switching

For top performance, the 3Com Baseline
10/100/1000 Switch 8-port and Baseline
Switch 2816 and 2824 deliver wirespeed
Gigabit throughput and a switching
capacity of up to 48 Gbps to handle the
most bandwidth-hungry applications.

*For U.S. and EU countries.

Advanced Switching Features

IEEE 802.1p Class-of-Service (CoS) traffic
prioritization makes sure that real-time
applications such as video and audio take
priority so they run effectively, and
enable the switches to operate in larger
networks.
Rack-Mounted or Free-Standing
Configuration

Small-business configurations can vary, so
the switches are designed to operate as a
free-standing or rack-mounted switch
with included mounting kit. The standard
19-inch, one rack-unit-high (1 RU) enclosure optimizes valuable office space.
Top Reliability with Limited Lifetime
Warranty

Sturdy design and construction pays off
in high reliability and long service life.
Limited Lifetime hardware warranty and
Advance Hardware Replacement* provide
peace of mind long after deployment.

Features and Benefits
Feature

Benefit

Powerful, Advanced Switching
Gigabit performance (3C16475A, 3C16476A,
3C16477, 3C16478, 3C16479)

Connect to servers and desktops running at 10, 100, or 1000 Mbps. 48 Gbps switching
capacity supports highest speed servers and desktops without additional network investment.

Optional SFP transceiver module support
(3C16478, 3C16479)

Baseline Switch 2226 and Switch 2250 include two Gigabit SFP transceiver slots that support
multimode shortwave fiber (1000BASE-SX) or multimode longwave fiber (1000BASE-LX)
connections. Mix and match SFP transceivers for media support flexibility.
