Troubleshooting
:
If the Link LED does not light up when a device is connected to its corre-
sponding port, check that both the hub and connected device are powered on. For devices
connected to the hub using twisted-pair cable, check that the cable length does not exceed
100 meters. You should have standard, straight-through cables and not crossover or other
specialized cables.

RJ-45 Fast Ethernet Ports
This hub includes 8 Fast Ethernet ports on the front panel; of which Port 8 can
also serve as a cascade port. Connect the MDI-X ports to network devices such
as workstations or servers, and the MDI port to a network interconnection
device such as another hub or switch. Remember that you cannot connect to
port 8 MDI-X and Port 8 MDI at the same time.
Note: Use Category 5 straight-through twisted-pair cable (STP or UTP) for all standard
connections. However, if you must cascade between two hubs using similar port types
at both ends of the cable, use crossover cable.
