About this Guide This guide provides instructions for instal-ling all of the products described below. These D-Link@ Ethernet Hubs are all Plug and Play compliant for easy installation. / - DE81 2TP+ DE-81 6TP DE-824TP When designing your cable configuration, it is necessary to strictly observe the Ethernet cabling rules.
Rack Mounting The Ethernet Hub may stand alone, or may be mounted in a standard 19-inch equip-ment rack. Rack mounting produces an orderly installation when you have a number of related network devices. Use the six supplied screws to fasten the supplied mounting brackets to either end of the hub, then fasten the hub into the rack.
Installing Network Cables Your Ethernet Hub is denominated as an 12-port, or 16-port, or 24-port Ethernet Hub according to the number of its front-panel 1OBaseT ports. Additionally it has two ports whose connectors are on the rear panel: one lOBase2 port (BNC connector), and one lOBase5 port (AUI connector).
Connect each station to the Ethernet Hub by means of a twisted-pair straight cable (10BaseT cable, Category 3, 4, or 5). Plug one RJ-45 connector into a front-panel port of the Ethernet Hub, and plug the other RJ-45 connector into the station’s Ethernet adapter.
connection involving a Model DE-816TP or Model DE-824 Ethernet Hub, there is the alternative of using a straight cable. Internal Crossover Features The Model DE-816TP Ethernet Hub and DE- 824TP Ethern.
+ Model DE-824TP Ethernet Hub The connector numbered as Port 1 is equipped with a switch labeled “Uplink” When the Uplink switch is in the “off (tall) position, the Port 1 connector is wired “straight” to the supporting circuitry, and Port 1 is then identical with each of the twenty-three other numbered ports.
two connectors would cancel one another, and the hub-to-hub connection would fail.) Thus the rule for making a hub-to-hub connection with twisted-pair cable is as follows: To make a hub-to-hub connection with a straight cable, Uplink must be selected at one end of the cable, and Uplink must not be selected at the other end of the cable.
Thin coax Segment v Sometimes several Ethernet Hubs must be co- located to support a larger array of stations than can be handled by a single Ethernet Hub. Then it is useful to stack the Ethernet Hubs by joining their BNC connectors with 0.5 meter patches of thin coaxial cable.
To connect the Ethernet Hub to a thick coaxial cable (lOBase cable), it is necessary to have a lOBase Ethernet transceiver (tap) on the cable at the Ethernet Hub’s position. Then run an AUI cable between the transceiver’s AUI connector and the AUI connector on the rear panel of the Ethernet Hub.
receptacle on the rear panel of the Ethernet Hub. Plug the other end of the power cord into an electric service outlet. Turn on power to the Ethernet Hub by switching its rear-panel power switch to the on position. LED Indicators LED indicators are located on the front panel of the Ethernet Hub.
One Link/Rx LED for each numbered port. Steady green (Link state) indicates that the port has good linkage to its partner device. Flashing green (Receive state) indicates that the port is receiving data from its partner device.
