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 giv
es optimal
performance to real-time applications
such as voice and video.
Future Protection
Gig
abit to the desk prepares your
network for the future at prices
comparable to those of some 10/100
switches
.
T
ri-speed operation at 10-,
100-, and 1000Mbps allows easy
migration to Gigabit speeds.
Inv
estment 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
w
eb browser.
Network Control
Network management can be done
thr
ough the embed
ded w
eb interface,
command line interface, or an SNMP
mana
gement station. This can be
further simplified with the use of
3Com Network Supervisor for config-
uration and tr
oubleshooting of
multiple devices on the network.
