3Com SuperStack II Switch 1000 24 Port 10Base-T and 1 Port 100Base-TX

SuperStack II Switch 1000

SuperStack II Switch 1000 provides 12 or 24 switched Ethernet ports and a 100BASE-T Fast Ethernet port for dramatically improved desktop-to-server traffic congestion. This switch gives you a simple way to eliminate Ethernet LAN traffic congestion at a very low per-port cost.

With SuperStack II Switch 1000, you can:

• Boost performance in Ethernet workgroups at a price well within a workgroup LAN's budget
• Open up server bottlenecks with a 100 Mbps Fast Ethernet connection based on state-of-the-art Ethernet/Fast Ethernet ASIC technology
• Configure a downlink to a high-speed Fast Ethernet, ATM, or 10 Mbps Ethernet backbone
• Migrate power users cost-effectively to high-performance switched ports

High Density, Low Price

• The switch offers 12 or 24 switched Ethernet ports, and can be stacked with the SuperStack II Switch 3000 Fast Ethernet switch to achieve higher port densities
• Per-port switching costs are close to those of traditional Ethernet repeating technology

Exceptional Performance

• 3Com's Ethernet/Fast Ethernet Switching ASIC, the BRASICA chip, provides wire-rate packet switching, giving you a convenient, high-speed connection between client stations on Ethernet and high performance file servers via 100 Mbps Fast Ethernet
• Full-duplex transmission on the high-speed ports supports greater distances over fiber (up to 2 kilometers) for campus networks, while doubling available network bandwidth and providing greater performance.
• An optional module provides an additional downlink to a high-speed Fast Ethernet copper or fiber backbone
• An optional ATM downlink module (155 Mbps OC-3c) is planned for the end of 1996
• Optional Transceiver Interface Modules provide a downlink to a conventional Ethernet backbone over a variety of cabling media types

Advanced Features

• Software-selectable switching options are available--cut-through/fast forward, cut-through/fragment-free, store-and-forward and intelligent switching mode--for greater switching flexibility
• The switch offers broadcast traffic control to protect against broadcast storms
• Intelligent switching mode automatically switches between cut-through and store & forward options
• LAN security architecture automatically disconnects unauthorized devices from the LAN
• Resilient links ensure fault tolerance via redundant connections to other network devices. The SuperStack II Redundant and Uninterruptible Power Supplies provide increased fault tolerance
• PACE (TM) technology delivers enhanced multimedia support and bandwidth utilization, eliminating multiple collisions, ensuring fair access to the LAN, and giving preferential treatment to high priority traffic on dedicated Ethernet segments
• IFM traffic management for flow control avoids packet loss under heavy load conditions
• Virtual LAN (VLAN) support reduces broadcast traffic loading, increases security and eases traditional administrative constraints based on user locations

Comprehensive SNMP Management

• Transcend WorkGroup and Enterprise Manager for Windows, and Transcend Enterprise Manager for UNIX, support the SuperStack II Switch 1000. They offer full SNMP management, including Remote Monitoring (RMON) for comprehensive per-port management; the Windows and UNIX versions of Transcend allow remote management from a PC or UNIX workstation, respectively
• Integrated RMON capability provides support for Alarms, Events, Statistics, History, Host, HostTopN and Matrix groups on a per port basis
• You can manage in-band or out-of-band using a local terminal or telnet, or centrally using Transcend applications
• 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.

Optional RPS or UPS

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.
