HOW TO USE THE BASELINE DUAL SPEED HUB 2 1 1 4 5 8 9 12 13 16 17 20 21 24 4 3 7 5 6 series, ensure that there are no more than four 10 Mbps hubs between any two devices on your network, as shown below. Numbered elements in this diagram refer to numbered sections in the text. These numbers, in bold, are used as references. Front Panel 1 16 or 24 RJ-45 10/100 Ports You can use these ports to connect 10BASE-T or 100BASE-TX devices (workstations and other equipment) to the Baseline Dual Speed Hub. As the ports are autosensing, the speed of the ports is determined automatically when you connect your equipment. 100BASE-TX To connect 100BASE-TX equipment, use 100BASE-TX Category 5 unshielded or shielded (screened) 100 Ohm TP cable. 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 telephone network. Only connect RJ-45 data connectors, network telephony systems, or network telephones to these sockets. Either shielded or unshielded data cables with shielded or unshielded jacks can be connected to these data sockets. Fast Ethernet Network Configuration Rules To remain within IEEE 802.3 100 Mbps Fast Ethernet rules, the maximum length of cable between the Baseline Dual Speed Hub and an attached device must not exceed 100 m (328 ft). Ensure that there are no more than two 100 Mbps hubs between any two devices on your network, and that the total cable distance (A+B+C) between the two devices does not exceed 205 m (672.4 ft), as shown below. AVERTISSEMENT: Points d’accès RJ-45. Ceux-ci sont protégés par des prises de données. Ils ne peuvent pas être utilisés comme prises de téléphone conventionnelles standard, ni pour la connection de l’unité à un réseau téléphonique central privé ou public. Raccorder seulement connecteurs de données RJ-45, systèmes de réseaux de téléphonie ou téléphones de réseaux à ces prises. Il est possible de raccorder des câbles protégés ou non protégés avec des jacks protégés ou non protégés à ces prises de données. If you connect two Baseline Dual Speed Hubs together, the link between them operates at 100 Mbps. 2 WARNHINWEIS: RJ-45-Porte. Diese Porte sind geschützte Datensteckdosen. Sie dürfen weder wie normale traditionelle Telefonsteckdosen noch für die Verbindung der Einheit mit einem traditionellem privatem oder öffentlichem Telefonnetzwerk gebraucht werden. Nur RJ-45-Datenanscluße, Telefonnetzsysteme or Netztelefone an diese Steckdosen anschließen. Entweder geschützte oder ungeschützte Buchsen dürfen an diese Datensteckdosen angeschlossen werden. MDI Switch This switch affects port 16 (3C16410) or port 24 (3C16411). Ports 1–15 (3C16410) or 1–23 (3C16411) are fixed as MDIX ports. Each can be connected to a device with an MDI port (such as most workstations) using a normal “straight through” TP cable. Port 16 or 24 is “switch selectable” using the MDI switch: Connect one end of the TP (twisted pair) cable to the RJ-45 port on the Baseline Dual Speed Hub and the other end to the appropriate RJ-45 port on the device. Use either shielded or unshielded data cables (with shielded or unshielded jacks) to connect to the devices. Out In this position, port 16 or 24 is an MDIX port. It can be connected to a device with an MDI port (such as most workstations) using a normal “straight through” TP cable. In In this position, port 16 or 24 is an MDI port. It can be connected to an MDIX port on a device (such as another hub) using a normal “straight through” TP cable. MDIX MDI The equipment that is connected to the Baseline Dual Speed Hub must not be set to operate in full duplex mode. It must be set to operate in autonegotiate or half duplex mode. 1 10BASE-T To connect 10BASE-T equipment, use 10BASE-T Category 3 or Category 5 unshielded or shielded (screened) 100 Ohm TP cable. Unit 1 Set switch to MDI (in) 4 5 13 8 9 16 17 Category 5 cable should be used with this product in structured wiring environments. This will ensure correct operation of all ports at 10 Mbps or 100 Mbps. 12 Unit 2 13 Ethernet Network Configuration Rules To remain within IEEE 802.3 10 Mbps Ethernet rules, the maximum length of cable between the Baseline Dual Speed Hub and an attached device must not exceed 100 m (328 ft).
