The 3C16965 SuperStack II Switch matrix module and matrix cable let you mix and match SuperStack II Switch 1100s and 3300s to improve throughput, share downlinks, and ease management. Use the matrix cable to connect two Switch 1100s or Switch 3300s and the matrix module to connect up to four switches* while conserving Fast Ethernet ports. The matrix module’s 4 x 1 Gbps backplane provides a 1 Gbps link between switches. Ultralow latency (maximum 300 nanoseconds) and hardware flow control ensure top performance at low cost. The entire stack can be managed as a single entity.


  • Any switch port can be configured to support roving analysis across the stack for greater visibility into traffic flows and RMON data; the module supports IEEE 802.1D and 802.1Q standards for VLANs and Ethernet Class of Service (CoS).


Four SuperStack II Switch 1100 or Switch 3300 units can be interconnected to form a stack that offers unrivaled performance and management features.

Each unit has a built-in connector at the rear of the unit called the matrix port. Two units can be connected back-to-back with a SuperStack II Switch matrix cable. To connect more than two units, a SuperStack II matrix module can be inserted into the high-speed module slot of one of the units in the stack, and a matrix cable can be used to connect to each switch in the stack.

Stacking provides the user with a plethora of benefits. These include the ability to manage in excess of 100 ports as a single logical entity. Configuration is therefore faster and simpler. Stacking also provides the user with the optional resilient IP addresses across the stack. Thus if a failure should occur, the resilient IP address can be used for management stacking using the SuperStack II Switch matrix module and cable, keeping front panel ports free and increasing the number of matrix ports in an aggregated system.


Transcend® network management
All SuperStack II switches are managed by 3Com Transcend® network management and control solutions. Transcend solutions give you end-to-end visibilityand control over all devices in your network with two levels of management: 1) technologies, such as embedded SmartAgent® software and RMON, within 3Com devices throughout the network, and 2) centralized highly automated applications at the network center for monitoring, configuring, and troubleshooting all devices in the network.

Ships with 3Com Transcend Network Supervisor
This PC-based application provides powerful, yet easy-to-use network management tuned to the needs of small-to-medium enterprises. Network devices are automatically discovered and network activity and stress monitored through an intuitive graphical interface focused on the tasks and information all managers need to take control of their network.

Web-based management
Manage your switches with any Web browser, either through direct or dial-up connection or across the LAN. This delivers ease of use and accessibility to network management personnel and reduces in-service costs, but still with full security.

Security — Disconnect Unauthorized Device (DUD)
LAN security architecture with DUD automatically disconnects unauthorized devices from the LAN.

Roving Analysis Port (RAP)
RAP allows a network analyzer attached to any unit in a stack to monitor any of the switch ports or virtual LANs (VLANs) in the stack. It also minimizes the time required for problem determination and resolution and maximizes switch uptime, thereby lowering your cost of ownership.

RMON support
Transcend software’s powerful combination of RMON (Remote Monitoring, a superset of SNMP MIB II) and embedded SmartAgent software 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. And Transcend software gives you the added benefit of RMON features in your network without the processing and memory costs usually associated with RMON. See the At-a-Glance RMON Support table for details on RMON groups supported by SuperStack II switches.

Class of Service (CoS)

CoS can be defined simply as a method for prioritizing various traffic types. 3Com switches can support two methods of enabling CoS on Ethernet networks. The first method is IEEE 802.1D (incorporating 802.1p), which enables eight levels of prioritization; and the second method is 3Com’s innovative PACE® technology, which allows the user to specify certain applications as high priority. A hardware feature, dual queues, is used to exploit these traffic prioritization schemes; the dual queues function—required for CoS—will automatically enable a second port buffer for high-priority traffic thereby allowing the traffic to bypass lower priority data for faster processing within the switch.
