Auto: In this mode of operation the Media Converter Module will
negotiate Ethernet parameters on the copper connection. This will
ensure the most optimal connection parameters will be in effect. If the
copper link partner does not support Auto negotiation, the C-100 and
CM-100 will default to 100 Mbps and Half Duplex mode.
Off: Auto Negotiation should only be turned off, if the copper link
partner does not support Auto Negotiation.
When the Auto Negotiation switch is set to the OFF position, the
Media Converter Module will operate at 100 Mbps and Full Duplex
mode.
