SuperStack II Switches

High-Performance, stackable, affordable switches for boosting performance and reducing congestion in workgroups

SuperStack II switches make high-performance, low-cost switching a reality at the workgroup level. The SuperStack II family of switches also allow you to eliminate traffic bottlenecks by configuring high-speed FDDI, Fast Ethernet, or ATM connections to servers and network backbones.

3Com's SuperStack(TM) II switches have revolutionized workgroup switching with fast, scalable, low-cost, highly manageable designs. All SuperStack II switches are part of 3Com's SuperStack II system, which allows you to enhance connectivity, functionality, and resilience by simply adding units to the stack.

SuperStack II switches feature powerful switching engines that extend full wire-speed bandwidth to the desktop and up to 155 Mbps to servers and the backbone. Plug-and-play installation and drag-and-drop configuration simplify management tasks.

Attractively priced for workgroups, yet providing exceptional functionality such as full RMON support, virtual LAN capabilities and full duplex switching, SuperStack II switches boost performance and eliminate client/server bottlenecks without expensive changes to the desktop PC or cabling system.

Power Supplies for Fail-Safe Operation

3Com gives you all the choices you need to ensure constant power to the stack. Depending on your requirements, you can select the Redundant Power System (RPS) or the Uninterrruptible Power System (UPS). Both units work with any product in the SuperStack II family.

The RPS is ideal as a back-up for individual power supplies in the SuperStack II units. It comprises two load-sharing bulk power supplies fed by two independent AC lines. Either of the two bulk supplies alone can support a stack of up to four Port Switch Hubs or other SuperStack II products.

The UPS fully protects your SuperStack II system from the effects of brown-outs or spikes that occur in outside power lines. With the UPS, you have assurance that your stack will keep running at all times, while being shielded from potentially damaging events on the external power grid. In addition, the UPS participates in 3Com management via an optional slide-in SNMP management module.

The switch supports a full complement of security-protected configuration and control features
You can get detailed per-port statistics and use gauges to automatically track error conditions, issue alarms, and optionally blip or disable a problem port

Virtual LAN Management

Allows you to set up logical workgroups regardless of the physical wiring structure, allowing flexible configuration.
VLANs can be used to control traffic patterns, to provide security and to control broadcast behavior.
You can use Transcend VLAN network management functionality to "drag and drop" users across a stack of switches and to easily set up workgroups remotely.

Switched Ethernet and Fast Ethernet Workgroups
Using 3Com products, you can easily combine switched Ethernet workgroups and 100BASE-T Fast Ethernet workgroups in one network. 3Com's Fast Ethernet products provide high-performance, cost-effective connections for backbone infra-structures and for workgroups.

In this example, a 3Com SuperStack II Switch 3000 FX (or SuperStack II Switch 3000 TX) switch accommodates 100 Mbps Fast Ethernet downlinks from a SuperStack II Hub 100 and a SuperStack II Switch 1000 Ethernet/Fast Ethernet switch. The SuperStack II Switch 3000 also extends Fast Ethernet links to a central server farm and to another switch in a second building. A NETBuilder II bridge/router provides connections to the wide area and FDDI campus networks.

SuperStack II Switch 1000 Ethernet to Fast Ethernet Switch

Remote Enterprise Monitoring and Analysis

3Com's Transcend offers a powerful combination of RMON (Remote Monitoring) and SmartAgent® software that reduces the processing burden on your management station, minimizes network traffic--and saves time by automatically monitoring and analyzing your network.

RMON tells you at a glance how the network is performing and who is using it the most. For example, Transcend Enterprise Manager for Windows now includes RMON features that give you network segment performance summary information, user profiles, and diagnostic help. Transcend's improved RMON error detection and diagnostics, including peak and average bandwidth utilization graphs, interpret and display threshold breaches and give you the ability to set thresholds and take action when these are exceeded.

Transcend saves time by freeing you from having to perform repetitive tasks. RMON alarms, integrated with the SmartAgent autocalibrate feature, automatically determine and set appropriate RMON thresholds for each port and station. And Transcend gives you the added benefit of RMON features in your network without the processing and memory costs usually associated with RMON.

SuperStack II Switch 3000 FX and Switch 3000 TX

The SuperStack II Switch 3000 switches provide high performance connections to Fast Ethernet networks over both fiber and copper cabling--ensuring high performance at a low cost. The SuperStack II Switch 3000 FX supplies five 100BASE-FX (fiber) ports and one 100BASE-TX (twisted-pair copper) port for workgroup devices and backbones. Its companion product, the SuperStack II Switch 3000 TX, offers eight 100BASE-TX ports for floor configurations. Both SuperStack II Switch 3000 models offer a slot for an optional downlink module and are part of 3Com's SuperStack system.
