Troubleshooting
1.
Verify power for the hub and all attached devices by checking the
PWR LED on the hub to make sure it lights green.
2.
Make sure that all devices are securely attached to the network and
that the adapter card(s) are operating.
3.
Follow the recommended cable distances and repeater limitations.
4.
A specific port may have been partitioned from the network.
Check for a defective network adapter or cable connection and
make sure that all devices are connected to the network by a single
path.
5.
If thin coaxial cable is used, make sure that the cable run is termi-
nated at both ends using a BNC terminator. If no cables or termi-
nators are connected to the BNC port, ignore the status LED for
this port.
