Note: Auto negotiation should only be turned off, if the copper link
partner does not support Auto Negotiation and fixed settings are
required by the copper link partner.
Auto: When enabled, the media converter will negotiate with its link partner to
determine the most optimal parameters for this connection. The S-1110P will
advertise capabilities of 10,100 and 1000 Mbps, full and half duplex as well as
pause, and remote fault capabilities to the link partner.
If the copper link partner does not support Auto negotiation, the S-1110P will
parallel detect to 10 or 100 Mbps and force Half Duplex mode as per IEEE
specifications.
Off: When the Auto Negotiation switch is set to the OFF position, the media
converter will not negotiate the Ethernet parameters with the copper link partner.
The parameters used by the media converter will be determined by the Duplex
(switch 4) and Speed (switch 5) DIP switch settings.
Note: This switch affects the behaviour of copper port 1 only; copper port 2 is
always set to Auto.

Smart Link Pass-Through
Standard Mode: In this mode, link on the fiber and copper sides can be brought up
and down independently of each other. A loss of link on either the fiber or copper
port can occur without affecting the other connection.
Smart Link Pass-Through 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 media converter has 2 copper or 2 fiber connections, then both must go down
in order to affect the other connection(s).
