Fast Ethernet Media Converter – Installation Guide
7
Pause (Switch 5)
Switch Position
Mode
Up (default) Enabled
Down Disabled
Enabled: When Auto Negotiation has been set to Auto (SW 1), the
media converter will use this setting for its Ethernet parameter
negotiation on the copper connection.
Disable: 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.
Loopback (Switch 6)
Switch Position
Mode
Up (default) Disabled
Down Enabled
Disabled: The loopback feature is disabled. This is the normal
position for regular operation. The switch must be set to this position
in order for data to pass through the media converter.
Enabled: This is a test mode. All data received on the receive (RX)
fiber connection is looped back to the transmit (TX) fiber connection.
The state of the copper is not relevant and no data or link status is
passed through to the copper side.
