Auto
: In this mode of operation the media converter 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 SR-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 will operate at 100 Mbps and Full Duplex mode.

In this mode, the link state on one connection is directly
reflected through the media converter to the other connection. If
link is lost on one of the connections, then the other link will be
brought down by the media converter.
If the installation has a media converter on both ends of the fiber
link and both are setup for Link Pass-Through, then a loss of
copper link on the far end device will propagate through both
media converters and will result in a loss of copper link at the near
end device. This would, therefore, resemble a direct copper
connection.
Disable
: In this mode, the links on the fiber and copper sides can
be brought up and down independently of each other. A loss of
link on either the fiber ports or copper ports can take place without
affecting the other connection.
