Numbered elements in this diagram refer to numbered sections in thetext. These numbers, in bold, are used as references.Front Panel1 16 or 24 RJ-45 10/100 PortsYou can use these ports to connect 10BASE-T or 100BASE-TX devices(workstations and other equipment) to the Baseline Dual Speed Hub. Asthe ports are autosensing, the speed of the ports is determinedautomatically when you connect your equipment.WARNING: RJ-45 Ports. These are shielded RJ-45 data sockets.They cannot be used as standard traditional telephone sockets,or to connect the unit to a traditional PBX or public telephonenetwork. Only connect RJ-45 data connectors, networktelephony systems, or network telephones to these sockets.Either shielded or unshielded data cables with shielded orunshielded jacks can be connected to these data sockets.AVERTISSEMENT: Points d’accès RJ-45. Ceux-ci sont protégéspar des prises de données. Ils ne peuvent pas être utilisés commeprises de téléphone conventionnelles standard, ni pour laconnection de l’unité à un réseau téléphonique central privé oupublic. Raccorder seulement connecteurs de données RJ-45,systèmes de réseaux de téléphonie ou téléphones de réseaux àces prises.Il est possible de raccorder des câbles protégés ou non protégésavec des jacks protégés ou non protégés à ces prises dedonnées.WARNHINWEIS: RJ-45-Porte. Diese Porte sind geschützteDatensteckdosen. Sie dürfen weder wie normale traditionelleTelefonsteckdosen noch für die Verbindung der Einheit miteinem traditionellem privatem oder öffentlichem Telefonnetzwerkgebraucht werden. Nur RJ-45-Datenanscluße, Telefonnetzsystemeor Netztelefone an diese Steckdosen anschließen.Entweder geschützte oder ungeschützte Buchsen dürfen an dieseDatensteckdosen angeschlossen werden.Connect one end of the TP (twisted pair) cable to the RJ-45 port on theBaseline Dual Speed Hub and the other end to the appropriate RJ-45 porton the device. Use either shielded or unshielded data cables (with shieldedor unshielded jacks) to connect to the devices.The equipment that is connected to the Baseline Dual SpeedHub must not be set to operate in full duplex mode. It must beset to operate in autonegotiate or half duplex mode.10BASE-TTo connect 10BASE-T equipment, use 10BASE-T Category 3 or Category 5unshielded or shielded (screened) 100 Ohm TP cable.Category 5 cable should be used with this product in structuredwiring environments. This will ensure correct operation of allports at 10 Mbps or 100 Mbps.Ethernet Network Configuration RulesTo remain within IEEE 802.3 10 Mbps Ethernet rules, the maximum lengthof cable between the Baseline Dual Speed Hub and an attached devicemust not exceed 100 m (328 ft). If you are connecting multiple hubs inseries, ensure that there are no more than four 10 Mbps hubs betweenany two devices on your network, as shown below.100BASE-TXTo connect 100BASE-TX equipment, use 100BASE-TX Category 5unshielded or shielded (screened) 100 Ohm TP cable.Fast Ethernet Network Configuration RulesTo remain within IEEE 802.3 100 Mbps Fast Ethernet rules, the maximumlength of cable between the Baseline Dual Speed Hub and an attacheddevice must not exceed 100 m (328 ft). Ensure that there are no morethan two 100 Mbps hubs between any two devices on your network, andthat the total cable distance (A+B+C) between the two devices does notexceed 205 m (672.4 ft), as shown below.If you connect two Baseline Dual Speed Hubs together, the linkbetween them operates at 100 Mbps.2 MDI SwitchThis switch affects port 16 (3C16410) or port 24 (3C16411). Ports 1–15(3C16410) or 1–23 (3C16411) are fixed as MDIX ports. Each can beconnected to a device with an MDI port (such as most workstations) usinga normal “straight through” TP cable. Port 16 or 24 is “switch selectable”using the MDI switch:H OW TO U SE THE BASELINE D UAL SPEED H UB16161134175 8209 1221 24435 72Out In this position, port 16 or 24 is an MDIX port.
