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.

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.
