Perle 10/100/1000 Ethernet Extended Temperature Media Converter
Installation Guide
5
Auto: When enabled, the media converter will negotiate with its
link partner to determine the most optimal parameters for this
connection. The S-1110-XT 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-1110-XT 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.

Link Mode (Switch 2) Switch Position Mode
Up (default) Standard Mode
Down 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 installation has a media converter on both ends of the fiber
link and both are set-up for Smart 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 link at the near end
device.
