User manual TRENDNET TE-500PLUS

[. . . ] The hub was designed and manufactured to give you years of trouble-free and reliable service. The hub is designed for plug-and-play installation and easy management. The hub provides an Uplink connection (shared with Port 1) for your network expansion via a RJ-45 MDI-II connector, making it easy to link two or more hubs together. The hub features LINK/RX LEDs to show the network connection and packet receiving status of each twisted pair port. [. . . ] This indicator blinks green when the hub is receiving data packets. This indicator blinks green when BNC port connection has network activities (network connection is established on the BNC port). Link/Receive: (LINK/RX) BNC: (TE-910plus only) Rear Panel Connectors RJ45 MDI-X Twisted-pair Jacks Use these jacks to connect Ethernet devices (server/workstation/print server) to the hub. These are MDI-X (Medium Dependent Interface, Cross-Wired) jacks, which means you can use ordinary stright-through twisted-pair cables to connect workstations and servers to the hub. If you need to connect another device with an MDI-X jack, such as another 4 hub or an Ethernet switch, you should use a crossver cable, or make the connection using the Uplink jack. Uplink Jack The Uplink jack is an MDI-II jack, which means you can connect the hub to an Ethernet device's (i. e. Hub or Switch) MDI-X port using straight-through cable. Port1 and the Uplink port is really the same port, except their pinouts are different. Do not use both Port-1 (1X) and the Uplink port at the same time. When uplinking hubs together, please do not exceed the "4-repeater (hub) count, 3 segments, and 2 populated segments" Ethernet connection rule. Basically, you can only uplink 4 hubs together using the UTP cable. The maximum CAT3, 4, or 5 twisted pair cable distance between two Ethernet devices is 100 meters. If you have question about this rule, please contact our support department at techsupport@trendware. com. BNC Port (TE910plus only) To connect the 10Base-2 network, attach the thin coax cable's BNC "T Connector" to the BNC port. Terminate the open end of the "T Connector" with a 50 Ohms Terminator. The coax cable should be marked RG58U or RG58 A/U, the maximum cable length between the two terminators is 185 meters, and you can connect up to 30 nodes on this cable. Power Jack For connecting the External power adapter. 5 Installation Installing the Hub The site where you install the hub may greatly affect its performance. When installing, consider the following pointers: Install the hub in a fairly cool and dry place, for the acceptable temperature and humidity operating ranges. Install the hub in a site free from strong ? [. . . ] 7 Twisted-pair Crossover Cables When making an uplink connection between two hubs (or between a hub and a switch, a bridge, or other Ethernet device) using MDI-X type jacks at both ends, you must use a crossover cable. In a crossover cable, two pairs of wires are switched at one end. Carry out the following steps to create a crossover twisted-pair cable: 1. Leave one end of the cable as -is, with the wiring on the RJ-45 connector unchanged. [. . . ]
