3COM ® SUPERSTACK ® 3 BASEL INE HUBS AND SWITCHES DATA SHEET

Baseline Hubs offerexceptional value byoffering the lowestcost-per-port in theSuperStack 3 familyand the most cost-effective way to addnew users to anetwork.

3Com SuperStack 3Baseline Hubs3Com SuperStack 3 Baseline hubsprovide high-quality connectivity solu-tions at entry-level prices for sharedEthernet networks that don’t requirecomprehensive management. Thesehubs are ideal for low-intensity net-work environments such as generaloffice applications using small net-worked files. With the lowest per-portcost in the SuperStack 3 family, theBaseline hubs offer exceptional value,and provide the most cost-effective wayto add new users to a network.

SuperStack 3 Baseline hubs provide 12-or 24-10BASE-T RJ-45 ports, allowingeach hub to connect either 12 or 24users. Each hub has an MDI/MDIXswitch to connect multiple hubs; thisallows you to expand the network usingnormal UTP cabling. The Baseline hubsprovide a transceiver interface slot,allowing connection to alternative net-work media, such as fiber or coax.Optional transceiver interface modulesare available. SuperStack 3 Baselinehubs are pre-configured and ready touse straight from the box.

• 12 or 24 RJ-45 10BASE-T connections

• MDI/MDIX switchable port allows forsimple cascading of hubs without theneed for special crossover cable.

• Slot for optional transceiver interfacemodule provides a connection tolegacy networking devices or fiber.

• Diagnostic LEDs indicate networktraffic, port status, and collisions,making it easy to spot-check faultsand check individual port status.

SuperStack 3 BaselineDual Speed HubsThe 3Com SuperStack 3 Baselinedual speed hubs give you the simplestway to migrate to high-speed FastEthernet networking while protectingyour existing network investment.Power users who require Fast Ethernetcan coexist with Ethernet users withoutdraining valuable network bandwidth.

Each Baseline dual speed hub has 12 or24 auto-sensing ports. The SuperStack 3

Baseline dual speed hub is pre-configured and ready to use straightfrom the box.

• 12 or 24 RJ-45 10BASE-T/100BASE-TX connections.

• Auto sensing on each port—automati-cally senses the speed of the networkdevice at the other end of the cableand optimizes performance.

• Integrated Ethernet to Fast Ethernetswitch provides seamless integrationbetween 10 Mbps and 100 Mbpssegments.

• Conforms as a Class II Fast Ethernetrepeater, which means that twoSuperStack 3 Baseline dual speedhubs can be cascaded in series (themaximum allowed according to theFast Ethernet specification).

• MDI/MDIX switchable port allows forsimple cascading of hubs without theneed for a special crossover cable.

• Diagnostic LEDs indicate port status,network traffic, and collisions on10 Mbps and 100 Mbps segments,making it easy to spot-check faultsand check individual port status.

SuperStack 3 Baseline10/100 SwitchesSuperStack 3 Baseline switches are idealfor any environment where raw powerand performance are needed, but man-agement is not required. The majorityof today’s networked devices (includingPCs, servers and printers) operate ateither 10 Mbps or 100 Mbps. TheSuperStack 3 Baseline 10/100 switchcan auto-sense whether a networkdevice supports 100 Mbps and automat-ically optimize the connection for thisthroughput. The SuperStack 3 Baseline10/100 switch plus 1000BASE-T pro-vides this same bandwidthoptimization, plus a single Gigabituplink. A Gigabit uplink allows manyusers to access a server or networkbackbone concurrently, and providesthe best possible performance andscalability for a LAN.

Baseline 10/100 switches provide 12 or24 10/100BASE-TX switched ports andare pre-configured and ready to usestraight from the box.

• The SuperStack 3 Baseline 10/100switch provides 12 or 24 RJ-4510BASE-T/100BASE-TX auto-sensingports that auto-negotiate connectionspeed and full-duplex/half-duplexmode.

• The SuperStack 3 Baseline 10/100switch plus 1000BASE-T provides 24RJ-45 10BASE-T/100BASE-TX auto-sensing ports that auto-negotiateconnection speed and full-duplex/half-duplex mode. Port 25 is a1000BASE-T port capable of auto-negotiation with the connected portto operate at 1000BASE-T full duplex.It auto-senses an MDI/MDIX connec-tion and can be used to connect toeither another 1000BASE-T switchport or to a 1000BASE-T server orworkstation without additionalconfiguration.

• IEEE 802.3x flow control ensuresnetwork traffic is not lost duringpeaks in traffic rates on high-throughput, full-duplex links.

• Diagnostic LEDs indicate networktraffic and port status of each port,making it easy to spot-check faultsand check individual port status.

No power failuresAll SuperStack 3 Baseline products areequipped with a connector to supportthe SuperStack 3 Advanced RedundantPower System (ARPS), for uninter-rupted operation in the event of apower supply failure. Power condition-ing and back-up products arerecommended by leading UPS vendorssuch as the American Power ConversionCorporation (APC). For details on rele-vant power products from APC seehttp://3com.apcc.com.

SuperStack 3 Baseline10/100/1000 SwitchesThe breakthrough SuperStack 3Baseline 10/100/1000 switch is ideal forusers who want the high-speed perfor-mance of 10/100/1000 switching but donot need sophisticated managementcapabilities. The SuperStack 3 Baseline10/100/1000 switch provides high per-formance switched connections to 10

Mbps, 100 Mbps, and 1000 Mbps hubs,servers, printers and workstations.

The SuperStack 3 Baseline 10/100/1000switch has six shielded RJ-45,10/100/1000 Mbps auto-negotiatingports on the front panel. Each10/100/1000 Mbps port automaticallydetermines the speed, duplex mode, andMDIX mode of the connected equipmentand provides a suitable switched con-nection (1000BASE-T connectionsoperate in full duplex mode only).

The SuperStack 3 Baseline 10/100/1000switch is pre-configured and ready touse straight from the box.

• The SuperStack 3 Baseline10/100/1000 switch provides six RJ-45 10BASE-T/100BASE-TX/1000BASE-T auto-sensing ports thatalso auto-negotiate connection speed,MDI/MDIX mode and full-duplex/half-duplex mode.

• IEEE 802.3x flow control ensures thatnetwork traffic is not lost duringpeaks in traffic rates on high-throughput, full-duplex links.

• Diagnostic LEDs indicate networktraffic and port status of each port,making it easy to spot-check faultsand check individual port status.

10/100/1000 Auto sensingAn auto-sensing port will automaticallyadjust its speed according to the equip-ment to which it is connected. Whenthe UTP cable is connected and the linkis first established, the hub or switchwill instantly and automatically sensethe maximum speed of the device at theother end of the cable. It will communi-cate with the other device at 1000 Mbps(for the 10/100/1000 tri-speed switch)or 100 Mbps (for a 10/100 switch hubor switch) or else it will run at 10 Mbps.

The SuperStack 3 Baseline 10/100/1000Switch also auto detects the cable type soit can easily be connected to any PC,server, hub or switch.

Note: Although you are able to useCategory 3 grade cabling for 10 Mbpslinks, you must use Category 5 gradecabling for links running at 100 Mbps or 1000 Mbps.

A Complete Solutionfor a Medium Enterprise orBranch OfficeThis shows a medium-sized office usinga combination of SuperStack 3 Baselineproducts. A mix of switched and shared10 Mbps and 10/100 Mbps delivershigher performance connections wherethey are needed, while keeping theoverall system cost to a minimum.

In the basement, a single SuperStack 3Baseline 10/100/1000 switch provides100 Mbps or 1000 Mbps switched linksto the floors and to each of the mainservers.

SuperStack 3 BaselineWithin the ManagedNetwork EnvironmentAs part of the SuperStack 3 family,SuperStack 3 Baseline products canbe integrated smoothly and effectivelyinto a 3Com enterprise network solu-tion that employs network managementbut that does not require it all the wayto the desktop.

In this example, network managementis used at the core of the network, andis connected to the workgroup by a sin-gle 1000 Mbps link.

High-performance, unmanagedconnections are then provided to desk-tops by the SuperStack Baselineproducts, as shown.

Used in this way, reliable, high-speednetwork connections can be deliveredto the desktop in an extremelycost-effective way, while ensuring com-plete compatibility and fitting in withthe corporate network structure.
