3Com®Baseline Switches

Wide-Ranging Unmanaged Family

Small to mid-sized businesses looking for a

switched LAN with or without high-speed

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.

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.

High-Performance 10/100/1000

Switching

For top performance, the 3Com Baseline

Switch 2808, 2816 and 2824 deliver wire-

speed Gigabit throughput and a switching

capacity of up to 48 Gbps to handle the

most bandwidth-hungry applications.

Plug-and-Play Unmanaged 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, elim-

inating the most common cabling errors

and simplifying installation. Autosensing

ports detect and adjust to the speed of the

connected device to optimize network

performance.

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) enclo-

sure optimizes valuable office space.

Warranty

Limited Lifetime Hardware Replacement. See
