Switch 3870 Gigabit Family
Product Overview
The 3Com
®
Switch 3870 family of managed
stackable 10/100/1000 Ethernet switches
provides secure, flexible LAN connectivity
for enterprise and branch office networks.
The Switch 3870 family offers Layer 2
switching and dynamic Layer 3 routing, as
well as robust security, quality of service
(QoS), and management features to deliver
intelligent Gigabit edge connectivity for
essential business applications.
Two switch models – stackable in any
combination up to eight units – include:
• 3Com Switch 3870 24-Port:
20-Port 10/100/1000; 4-Port dual-person-
ality 10/100/1000 or Gigabit SFP; dual
built-in 10-Gbps stacking ports; expan-
sion slot supporting 10-Gigabit
(XENPAK) module
• 3Com Switch 3870 48-Port:
44-Port 10/100/1000; 4-Port dual-person-
ality 10/100/1000 or Gigabit SFP; dual
built-in 10-Gbps stacking ports; expan-
sion slot supporting 10-Gigabit
(XENPAK) module
Why Gigabit to the Desk?
It is time to consider "Gigabit to the desk"
as an alternative to 10/100 switching:
• Give users a 10x improvement in
performance when compared to legacy
10/100 edge connections. Reduce
network latency. Prepare the network
for supporting high quality video and
voice communication.
• Pricing for Gigabit is closer and closer to
that of 10/100 switching, making it more
justifiable to upgrade to the higher speed.
• Gigabit speeds are increasingly being
supported by new servers and worksta-
tions. Prepare the network to deliver
optimum speed.
• Migration is easy, with 10-, 100-, and
1000Mbps operation that automatically
adjusts to the maximum available speed.
No worries about backward compatibility.
Secures the Network
Essential security features provide user
and device authentication, enforce access
control for switch management, and
enhance overall network security to
protect critical resources and information.
The Switch 3870 also functions as an inte-
gral part of the 3Com Quarantine*
solution, enabling automatic containment
of security threats.
Empowers Application Convergence
The Switch 3870 family provides a 10x
improvement in performance with reduced
network latency. Combined with
advanced quality of service (QoS) and
traffic management features prepares the
network to support high quality video and
voice communication.
Increases Flexibility and Scalability
The Switch 3870 family employs a flexible
design with user-configurable “dual
personality” Gigabit Ethernet interfaces,
and the ability to stack up to eight switch
units (384 10/100/1000 connectivity ports)
that can be managed as a single entity.
Each Switch 3870 also has an expansion
slot capable of supporting an additional
10Gbps full duplex (20Gbps total) high-
speed Ethernet connection.
Enhances Management and Control
Easy to use and manage, the Switch 3870
family is designed to increase business
productivity by reliably supporting busi-
ness applications that drive productivity
improvements.
