DATA SHEET
OVERVIEW
3Com®Baseline switches provide cost-effective Layer 2 10/100 and
10/100/1000 Ethernet switching for LANs that don't need management
capabilities. Simple to install and economical to own, they feature
wirespeed performance on fixed-configuration, rack-mountable platforms.
KEY BENEFITS
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 bps)
support easily handles higher speed desktop and office server connections.
HIGH-PERFORMANCE 10/100/1000 SWITCHING
For top performance, the 3Com 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.
PLUG-AND-PLAY UNMANAGED OPERATION
3Com Baseline switches operate straight out of the box, with no
configuration required. Auto DI/ DIX 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.
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.
THREE-YEAR HARDWARE WARRANTY
3Com gives a Three-Year Limited Hardware Warranty on the Baseline
Switch Family. Advance Hardware Replacement, with Next Business
Day shipment in most regions, is also provided.
