Troubleshooting System
Problems
This section addresses some of the system
problems that can be corrected using the options
on the 10BASE-FB Transceiver. If problems occur,
always check the diagnostics indicators on the
Transceiver.
Excessive Collisions
Collisions can be caused by loops in the
10BASE-FB network. Such loops cause every
packet to collide with itself. If you cannot locate
the loop, try segmenting your network (by dis-
connecting Star Couplers, or ONline and ONcore
Hubs one at a time) until the loop is located.
