Fast EtherHub Installation Manual INTRODUCTION General Description The EH3008C and EH3012C 100BASE-TX 8/12 port stackable hubs are entry level 100Mbps Fast Ethernet hubs. They are built around a standard 19-inch chassis which allows stand-alone or rack-mounted operation. These 100BASE-TX 8/12 port stackable hubs are economical Fast Ethernet hubs with 8/12 100BASE-TX (RJ-45) ports for workstation connection.
Fast EtherHub Installation Manual Key Features ❑ Compliant with the IEEE802.
Fast EtherHub Installation Manual Package Contents Check your package contents for the following parts: æ 8/12 port 100BASE-TX Fast Ethernet Stackable Hub (Fast EtherHub-8se or Fast EtherHub-12se) æ Power Cord æ Stackable Cable (D-Sub 25 pins) æ Rack-mount Kit æ User’s Manual If any of these pieces are missing or are damaged, please contact your dealer immediately.
Fast EtherHub Installation Manual Hardware Description The Front Panel The front panel contains the 8/12 Shielded Twisted-Pair (STP) ports, one uplink port, and LED indicators. Shielded Twisted- Pair (STP) ports Use any one of the STP ports for connection to a 100BASE-TX node using Category 5 UTP cabling. Each of these ports provides 100Mbps bandwidth for connection to a workstation or server.
Fast EtherHub Installation Manual LED indicators The front panel LED indicators help you monitor the status of each port and connected segments. There are 4 different LEDs on the front panel; including power (PWR), collision (COL), LINK/ACTIVITY and ERROR. This table lists the LEDs and their respective functions.
Fast EtherHub Installation Manual The Rear Panel The rear panel of the hub contains the power socket , 2 D-Sub connectors (25 pins) and air fans. Power Socket The power socket accepts AC power of 100 - 240V at 50 - 60 Hz.
Fast EtherHub Installation Manual HARDWARE INSTALLATION Quick Installation Procedure 1. 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.
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.
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.
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.
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.
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.
Fast EtherHub Installation Manual TROUBLESHOOTING This chapter contains information to help you solve problems. If these hubs are not functioning properly, make sure they were set up according to instructions in this manual. If the hubs don’t connect to the network: ➊ Check the LINK/ACTIVITY LED lights on the front panel. If the LINK/ACTIVITY LED isn t lit, check all connections at the adapter and the hub. Make sure the adapter drivers are loaded. ➋ Try another port on the hub.
Fast EtherHub Installation Manual Other Important Tips ➀ Make sure no more than 100 meters of cable are used between the hub and the desktop. ➁ Verify that the cabling type used is correct. (Category 5 UTP cable) ➂ Make sure the network adapter cards installed in the workstations and cable connections are in good working condition. ➃ Hubs connected via the backplane ports cannot be cascaded via the uplink port. When cascading hubs, limit the cascade to two hubs, and limit the interhub cabling to 5 meters.
