1. Power LED is not lit
l Check if the power cord is properly connected to the external switching 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
l Check the power switch of the network devices attached to the hub; make sure
they are turned ON.
l Check the network cables; make sure they are properly connected to the hub and
the network devices.
l Check the network cables; make sure the cables comply with EIA/TIA 568
specification. Use straight-through Category 5 cables for 100Mbps connection and
Category 3 or higher cables for 10Mbps connection.
l Check the slide switch and make sure it's in normal position when you use the last
port on the hub to connect to workstations or file servers.
3. 8th port's Link Status LED is not lit when it is uplinked to another hub
l Make sure the uplink slide switch is shifted to "uplink" position.
l Check the network cable; make sure it is properly connected to both hubs. The
slide switch next to the last port should be shifted to "uplink" position. One end of
the cable should be connected to last port while the other end of the cable should
connected to a regular port. Do not connect the cable to both uplink ports.
l Check the network cable; make sure the cable complies with EIA/TIA 568
specification. Use CAT5 cables for 100Mbps connection and minimum CAT3
cables for 10Mbps connection.
l Check the network cable; make sure the maximum length does not exceed 5
meters (15ft) when this port is used for 100Mbps connection.
4. Collision LED flashes constantly
l Remove all the network cables; connect the cables back one by one to isolate the
source of the collision.
l Check the network cable, inferior cable quality will result in excessive collision
and error packets.
