If you have IEEE 802.3 repeaters in your network, ensure that the SQE Mode and Alternate Colli- sion Mode switches are disabled for
Late Collisions and Failure to Defer
Late collisions can be caused by exceeding the distance rules of Ethernet, or by controllers that do not fully comply 100% with the IEEE standard.
To verify that your network satisfies the distance rules, refer to the configuration rules in:
■
■ONline or ONcore Ethernet
Activating the Alternate Collision Mode on the Transceiver may solve this problem in many cases.
