Page 9: Hardware Installation
Fast EtherHub Installation Manual HARDWARE INSTALLATION Quick Installation Procedure Place the hub on a smooth surface or mount it on a rack. Connect power cord to hub and plug in. 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. - Page 10 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.
- Page 11 Fast EtherHub Installation Manual Setting Up 100BASE-TX Stackable Hubs Put the 100BASE-TX stackable hub on the flat surface. Ensure the power is off before stacking the hub. Attach the power cord and turn on power to the hub. 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.
- Page 12 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.
- Page 13 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.
- Page 14 Fast EtherHub Installation Manual 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 I repeater standards when stacked.
