Auto:
When Auto Negotiation has been set to Auto (SW 2), the
media converter will use this setting for its Ethernet parameter
negotiation on the copper connection.
Half:
The media converter will not negotiate support for the Pause
feature.
NOTE
: The media converter will not act on, or generate any
Ethernet Pause messages, but will pass them through to the end
device. This switch setting is provided so that the attached device
(near end) can negotiate its Ethernet parameters as if it was
negotiating directly with the far end device. The Pause switch
setting on the media converter should match the capabilities of the
far end device.

connection. The state of the copper is not relevant and no data or
link status is passed through to the copper side.
