Verifying System Operation
Verify that all attached devices have a valid connection. The hub monitors
link status for each port. If any device is properly connected to the hub and
transmitting a link beat signal, the Link indicator lights up for the corre-
sponding port. If the Link indicator fails to light up when you connect a
device to the hub, check the following items:
■
Be sure the twisted-pair cable is properly attached to the connected
device and the hub. Verify that the RJ-45 plug snaps into place when
attached.
■
Verify that if the cable is connected to an MDI-X port on the hub, the
other end must be to an MDI port of the network device and vice versa.
Test by alternately connecting to the 8MDI and 8MDI-X ports.
■
See if the twisted-pair cable is functioning properly by using it for
another port and attached device that already displays valid indications
when connected to the network.
■
Check the length of the twisted-pair connection to be sure it does not
exceed 100 meters.
■
Verify that the cable is Category 5.
■
Test the adapter for an attached workstation by trying it in another com-
puter that has been successfully connected to the network.
If you still can’t resolve the problem, please refer to Troubleshooting in
Appendix A.
