Connecting Network Devices
1. Connect a Category 5 patch cable to the RJ45 jack on your computer’s network card.
(The RJ45 jack looks like an oversized phone jack)
2. Connect the other end of the cable to port 1, 2, 3, 4 or 5 on the hub (not the uplink
port)
3. Repeat steps 1 and 2 for all the computers you want to network.
Uplink to Another Hub
Use the Uplink port (the first port) to connect to another hub. Connecting cables must
comply with EIA.TIA 568 specifications and Category 3, 5 standards to connect hubs.
Connecting the Power
Connect the power cord to the power socket on the external power adapter. Connect the
DC power jack to the DC power socket on the rear panel of the hub. Connect the power
cord to the power outlet. The Power LED on the front panel should be lit.
Troubleshooting
1. Power LED is not lit
• Check if the power cord is properly connected to the external power adapter and the
power outlet. Make sure the DC power jack is firmly plugged into the power socket
of the hub.
2. Link Status LED is not lit
• Check the power switch of the network devices attached to the hub; make sure they
are turned ON. Check the network cables; make sure they are properly connected to
the hub and network devices.
• Check the network cables; make sure the cables are comply with EIA/TIA 568
specification. Use straight-through Category 3 or 5 cables for connection.
3. The first port’s Link Status LED is not lit when it is uplinked to another hub
• Make sure the cable is connected to the uplink port.
• Check the network cable; make sure it is properly connected to both hubs. One end
of the cable should be connected to the uplink port while the other end of the cable
should be connected to a regular port. Do not connect the cable to both uplink ports.
• Check the network cable; make sure the cable complies with EIA/TIA
568 specifications.
4. Collision LED flashes constantly
• Remove all the network cables; connect the cables back on by one to isolate the
source of collision.
• Check the network cable. Inferior cable quality will result in excessive collision and
error packets.
