Place the hub on a smooth surface or mount it on a rack. 2. Connect power cord to hub and plug in. 3. Connect workstations to hub using Category 5 UTP cabling. ? Plug an RJ-45 connector into any port on the hub (other than the Uplink port), and plug the other end into the RJ-45 port on the workstation’s Fast Ethernet card. Distance between the hub and the workstation can be no more than 100 meters. 4. Connect each device (up to 8/12) on your network using the process described in Step 3. ? Make sure you have the correct wiring To reliably operate your network at 100Mbps, you must use Unshielded Twisted-Pair (UTP) Category 5, or better, Data Grade wire. While Category 3 or 4 wire may initially seem to work, it will soon cause data loss. 7 Fast EtherHub Installation Manual Select an Appropriate Location A good location is at or near the center of all the computers you want to link, close to the trunk segment and the other devices you want to connect, and near a convenient power outlet. ? The cable route should not be near any power lines. After you have decided on a particular location, you can place the hub on the top of a table or a shelf, or mount it on a rack. You may mount the hub on any EIA standard size 19-inch mounting rack. First attach the supplied mounting brackets onto the sides of the hub with screws. Afterwards, secure the hub onto the rack by screwing on the mounting brackets. 8 Fast EtherHub Installation Manual Setting Up 100BASE-TX Stackable Hubs 1. Put the 100BASE-TX stackable hub on the flat surface. ? Ensure the power is off before stacking the hub. 2. Attach the power cord and turn on power to the hub. 3. Connect one end of the D-Sub (25 pins) stack cable to the OUT port on the first hub and the other end to the IN port on the next hub in the stack. ? Do not connect OUT to OUT or IN to IN port on different hubs. 4. Screw on the D-Sub (25 pins) connectors if necessary. 5. Repeat steps 2-3 until all hubs are combined together in the stack. You should have a simple chain starting at the OUT port on the first hub, and ending at the IN on the last hub. You can stack up to 4 hubs in this manner. Note that a stack acts as a single repeater set. ?The hub’s backplane ports allow cascading only up to 4 hubs. 9 Fast EtherHub Installation Manual CONFIGURATION Standard-Alone The configuration of a simple stand-alone hub is illustrated as below. The maximum distance between the hub and the workstation is 100 meters. 10 Fast EtherHub Installation Manual Uplink Multiple Hubs If you want to connect more than 8/12 ports, you can use the uplink port to connect to another hub. In compliance with the IEEE802.3u Class II specification, two repeaters can be cascaded using 5 meters of cable in a single collision domain. 1. Connect a Category 5 UTP cable to the UPLINK port (Port 8/12) on the first hub. 2. Connect the other end of the UTP cable to any of Ports 1 - 8/12 on the second hub (i.e., do not connect it to the UPLINK port on the second hub). ? You do not need crossover cable if you use the uplink port. ? Do not connect the uplink port (Port 8/12) on first hub to the uplink port (Port 8/12) on the second hub. 11 Fast EtherHub Installation Manual 12 Stacking Multiple Hubs The 100BASE-TX stackable hub comes with stackable backplane port for cascading up to 4 hubs. As your network grows, this stackable feature allows you to add additional units for expansion. Depending on the models used, you will be able to stack up to 32/48 ports. Note the hubs follow Class...
