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.
