3COM SUPERSTACK 3 3870 GIGABIT, LAYER3, STACKABLE SWITCH

============================================
3COM Superstack 3 3870 Gigabit, Layer3, Stackable Switch
============================================
Please Note:
This Switch is higher performance than the Cisco Catalyst 2960G, 3650G, 3750G. Very robust and feature rich switch. The switch is fully tested, inspected by a Cisco Engineer. The Switch has been updated to the latest 3COM Firmware.

It can be managed via a Web Browser, GUI Manageable, or the Command Line Interface. Very easy to administer. Ideal for Small, Medium and Large Business, Server Farm, Data Center, Aggregation Switch and Bandwidth-Intensive Application.

This switch is not only layer 2 but a Layer3 switch as well, which means it can do routing exactly as a router between different VLANs and subnets, no more bugging the router with Intervlan routing and creating bottlenecks if you know what Im talking about! There are 2 slots in the back of the switch that can be used for stacking or two 10Gigabit ports. A lot of Administration Guide, User Guides and software utilities will come with this switch on a CD.

Enables Secure Converged Networks with
Stackable Gigabit to the Desk at pricing similar to 10/100
End-to-end network security
Layer 2/3 switching and routing
Scalable up 384 Gigabit users per stack
Available 10-Gigabit connectivity

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-personality 10/100/1000 or Gigabit SFP; dual built-in 10-Gbps stacking ports; expansion slot supporting 10-Gigabit (XENPAK) module.

3Com Switch 3870 48-Port, 44-Port 10/100/1000; 4-Port dual-personality 10/100/1000 or Gigabit SFP; dual built-in 10-Gbps stacking ports; expansion 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 workstations. 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 integral 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) highspeed Ethernet connection.

Enhances Management and Control:
Easy to use and manage, the Switch 3870 family is designed to increase business productivity by reliably supporting business applications that drive productivity improvements.

Scalability:
Enhanced 10/100/1000 Layer 2 switching and dynamic Layer 3 routing solution delivers scalable wirespeed Gigabit performance, with integrated stacking up to eight units high, or 384 Gigabit ports. Each Switch comes with integrated dual full duplex 10Gbps stacking ports on the back of the
unit, providing a total stacked capacity of 40Gbps, plus an expansion slot capable of supporting an additional 10Gbps full duplex (20Gbps total) high-speed Ethernet connection. This enables the 156Gbps switching capacity to provide wirespeed switching on
all ports. Stack-wide link aggregation enables highperformance 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 that supports a single-port 10-Gigabit Ethernet module, with CX-4, LR, or ER XENPAK ports that can be used to connect back to the network core.

Ease of Use:
Dynamic routing with RIP (Routing Information Protocol) allows automatic updating of Layer 3 network topologies. Speed and duplex mode on all ports are negotiated automatically, preventing the possibility for improper configuration. Switches detect and adjust to cross-over or straight through cable connections via “Auto MDI/MDIX” feature, eliminating the need for different cables to interconnect network devices.

Security:
The Switch 3870 family ensures secure access to resources using standard 802.1X network access control combined with RADIUS authentication. Additionally, RADIUS Authenticated Device Access (RADA) enables authentication of attached devices via MAC address for an additional
level of endpoint security. Port-based Access Control Lists (ACLs) effectively enable usage policies at each point of access to the network via the switch. Secure Shell (SSHv2), Secure Sockets Layer
(SSL/HTTPs) and SNMPv3 support ensure secure management access to switches via authentication and encryption of management traffic.

Powerful Management:
Comprehensive support within the 3Com management application software suite, including the standalone packages 3Com Enterprise Management Suite or 3Com Network Director. 3Com Network Supervisor may also be used in smaller networks.
