3Com SuperStack 3 Baseline Hubs
3Com SuperStack 3 Baseline hubs provide high-quality connectivity solutions at entry-level prices for shared Ethernet networks that don't require comprehensive management. These hubs are ideal for low-intensity network environments such as general office applications using small networked files. With the lowest per-port cost in the SuperStack 3 family, the Baseline hubs offer exceptional value, and provide the most cost-effective way to add new users to a network. SuperStack 3 Baseline hubs provide 12or 24-10BASE-T RJ-45 ports, allowing each hub to connect either 12 or 24 users. Each hub has an MDI/MDIX switch to connect multiple hubs; this allows you to expand the network using normal UTP cabling. The Baseline hubs provide a transceiver interface slot, allowing connection to alternative network media, such as fiber or coax. Optional transceiver interface modules are available. SuperStack 3 Baseline hubs are pre-configured and ready to use straight from the box. * 12 or 24 RJ-45 10BASE-T connections * MDI/MDIX switchable port allows for simple cascading of hubs without the need for special crossover cable. * Slot for optional transceiver interface module provides a connection to legacy networking devices or fiber. * Diagnostic LEDs indicate network traffic, port status, and collisions, making it easy to spot-check faults and check individual port status.
Baseline dual speed hub is preconfigured and ready to use straight from the box. * 12 or 24 RJ-45 10BASE-T/ 100BASE-TX connections. * Auto sensing on each port--automatically senses the speed of the network device at the other end of the cable and optimizes performance. * Integrated Ethernet to Fast Ethernet switch provides seamless integration between 10 Mbps and 100 Mbps segments. * Conforms as a Class II Fast Ethernet repeater, which means that two SuperStack 3 Baseline dual speed hubs can be cascaded in series (the maximum allowed according to the Fast Ethernet specification). * MDI/MDIX switchable port allows for simple cascading of hubs without the need for a special crossover cable. * Diagnostic LEDs indicate port status, network traffic, and collisions on 10 Mbps and 100 Mbps segments, making it easy to spot-check faults and check individual port status.
Baseline Hubs offer exceptional value by offering the lowest cost-per-port in the SuperStack 3 family and the most costeffective way to add new users to a network.
SuperStack 3 Baseline 10/100 Switches
SuperStack 3 Baseline switches are ideal for any environment where raw power and performance are needed, but management is not required. The majority of today's networked devices (including PCs, servers and printers) operate at either 10 Mbps or 100 Mbps. The SuperStack 3 Baseline 10/100 switch can auto-sense whether a network device supports 100 Mbps and automatically optimize the connection for this throughput. The SuperStack 3 Baseline 10/100 switch plus 1000BASE-T provides this same bandwidth optimization, plus a single Gigabit uplink. A Gigabit uplink allows many users to access a server or network backbone concurrently, and provides the best possible performance and scalability for a LAN. Baseline 10/100 switches provide 12 or 24 10/100BASE-TX switched ports and are pre-configured and ready to use straight from the box.
SuperStack 3 Baseline Dual Speed Hubs
The 3Com SuperStack 3 Baseline dual speed hubs give you the simplest way to migrate to high-speed Fast Ethernet networking while protecting your existing network investment. Power users who require Fast Ethernet can coexist with Ethernet users without draining valuable network bandwidth. Each Baseline dual speed hub has 12 or 24 auto-sensing ports. The SuperStack 3

* The SuperStack 3 Baseline 10/100 switch provides 12 or 24 RJ-45 10BASE-T/100BASE-TX auto-sensing ports that auto-negotiate connection speed and full-duplex/half-duplex mode. * The SuperStack 3 Baseline 10/100 switch plus 1000BASE-T provides 24 RJ-45 10BASE-T/100BASE-TX autosensing ports that auto-negotiate connection speed and fullduplex/half-duplex mode. Port 25 is a 1000BASE-T port capable of autonegotiation with the connected port to operate at 1000BASE-T full duplex. It auto-senses an MDI/MDIX connection and can be used to connect to either another 1000BASE-T switch port or to a 1000BASE-T server or workstation without additional configuration. * IEEE 802.3x flow control ensures network traffic is not lost during peaks in traffic rates on highthroughput, full-duplex links. * Diagnostic LEDs indicate network traffic and port status of each port, making it easy to spot-check faults and check individual port status.
No power failures
Mbps, 100 Mbps, and 1000 Mbps hubs, servers, printers and workstations. The SuperStack 3 Baseline 10/100/1000 switch has six shielded RJ-45, 10/100/1000 Mbps auto-negotiating ports on the front panel. Each 10/100/1000 Mbps port automatically determines the speed, duplex mode, and MDIX mode of the connected equipment and provides a suitable switched connection (1000BASE-T connections operate in full duplex mode only). The SuperStack 3 Baseline 10/100/1000 switch is pre-configured and ready to use straight from the box. * The SuperStack 3 Baseline 10/100/1000 switch provides six RJ-45 10BASE-T/100BASE-TX/ 1000BASE-T auto-sensing ports that also auto-negotiate connection speed, MDI/MDIX mode and fullduplex/half-duplex mode. * IEEE 802.3x flow control ensures that network traffic is not lost during peaks in traffic rates on highthroughput, full-duplex links. * Diagnostic LEDs indicate network traffic and port status of each port, making it easy to spot-check faults and check individual port status.
10/100/1000 Auto sensing
The SuperStack 3 Baseline 10/100/ 1000 Switch is ready to use straight from the box.
All SuperStack 3 Baseline products are equipped with a connector to support the SuperStack 3 Advanced Redundant Power System (ARPS), for uninterrupted operation in the event of a power supply failure. Power conditioning and back-up products are recommended by leading UPS vendors such as the American Power Conversion Corporation (APC). For details on relevant power products from APC see http://3com.apcc.com.
SuperStack 3 Baseline 10/100/1000 Switches
The breakthrough SuperStack 3 Baseline 10/100/1000 switch is ideal for users who want the high-speed performance of 10/100/1000 switching but do not need sophisticated management capabilities. The SuperStack 3 Baseline 10/100/1000 switch provides high performance switched connections to 10
An auto-sensing port will automatically adjust its speed according to the equipment to which it is connected. When the UTP cable is connected and the link is first established, the hub or switch will instantly and automatically sense the maximum speed of the device at the other end of the cable. It will communicate with the other device at 1000 Mbps (for the 10/100/1000 tri-speed switch) or 100 Mbps (for a 10/100 switch hub or switch) or else it will run at 10 Mbps. The SuperStack 3 Baseline 10/100/1000 Switch also auto detects the cable type so it can easily be connected to any PC, server, hub or switch. Note: Although you are able to use Category 3 grade cabling for 10 Mbps links, you must use Category 5 grade cabling for links running at 100 Mbps or 1000 Mbps.

As part of the SuperStack 3 family, SuperStack 3 Baseline products can be integrated smoothly and effectively into a 3Com enterprise network solution that employs network management but that does not require it all the way to the desktop. In this example, network management is used at the core of the network, and is connected to the workgroup by a single 1000 Mbps link. High-performance, unmanaged connections are then provided to desktops by the SuperStack Baseline products, as shown. Used in this way, reliable, high-speed network connections can be delivered to the desktop in an extremely cost-effective way, while ensuring complete compatibility and fitting in with the corporate network structure.
