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

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

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.
