3 Switch 3870
24- and 48-Port Stackable Switches
Key Benefits
Scalability
Enhanced Layer 2 10/100/1000 LAN
switching solution delivers scalable
wirespeed Gigabit performance, with
integrated stacking up to eight units
high, or 384 Gigabit ports, with high-
bandwidth 40Gbps stacking.  Stack-
wide link aggregation enables high-
performance connectivity to the core
of the network, with up to eight
ports from different units aggregated
together to improve resiliency and
uptime.
Performance
24 or 48 built-in copper Gigabit
ports, including four dual-purpose
ports supporting copper links or SFP
adapters for easy, flexible connection
to fiber-based Gigabit media. 
Port-based rate-limiting enables the
bandwidth on each port to be
restricted, so power users can receive
the full bandwidth available while
non-key users can be throttled down,
preserving network bandwidth and
allowing maximum control of
network resources.  Built-in packet
prioritization gives optimal
performance to real-time applications
such as voice and video.
Future Protection
Gigabit to the desk prepares your
network for the future at prices
comparable to those of some 10/100
switches.  Tri-speed operation at 10-,
100-, and 1000Mbps allows easy
migration to Gigabit speeds.  
Investment protection is further
enhanced with switching silicon
designed to support multilayer
switching, and a module slot with
10Gbps connections capable of
supporting high-speed Ethernet.
Ease of Use
Automatic selection of the optimal
speed and duplex mode of cables
connected to it prevent mis-configu-
ration of the network.  The switches
also detect and adjust to cross-over or
straight-through cable connections—
a feature called auto MDI/MDIX—
eliminating the need for specific
cables.
Security
IEEE 802.1X network login enables
intrusion prevention on the network,
requiring users to authenticate with a
central standards-based RADIUS
server for ease of management;
unauthorized users are kept off the
network. 
Management of the switch can be
implemented using Secure Shell (SSH)
and Secure Sockets Layer (SSL /
HTTPS) encryption, preventing
unauthorized remote access to the
switch over IP networks or from a
web browser.
Network Control
Network management can be done
through the embedded web interface,
command line interface, or an SNMP
management station.  This can be
further simplified with the use of
3Com Network Supervisor for config-
uration and troubleshooting of
multiple devices on the network.
