Fiber Negotiation (Switch 1)
Switch Position Mode
Up (default) Auto
Down Off
Auto: In this mode of operation the Media Converter will negotiate
Ethernet parameters on both the copper and the fiber connection.
This will ensure the most optimal connection parameters will be in
effect. If connecting to another Perle Gigabit Media Converter, this
parameter should be set to Auto.
Off: Fiber Negotiation should only be turned off, if the fiber
link partner does not support fiber link negotiations
.
When the Fiber Negotiation switch is set to the OFF position, the
Media Converter Module will negotiate the Ethernet parameters
with the copper link partner. The parameters used in this
negotiation will be determined by the Duplex (switch 4) and Pause
(switch 5) switch settings.
