Force 100 Mode
There is no Auto Negotiation in either of the Force modes.
Auto Negotiation (PCI Version)
When connecting two McPC 10/100s between two end stations (devices such as
switches, hubs and repeaters), all devices in the media conversion should ideally
support, and be utilizing, Auto Negotiation functionality. While it is possible to
have Auto Negotiating devices on one side of the media conversion and fixed
(non-Auto Negotiating) devices on the other, link LEDs will react differently
depending on where a link fault occurs. Therefore, IMC recommends:
Configuring every device in the media conversion for Auto Negotiation.
For installations where Auto Negotiation is NOT possible from one end of
the media conversion to the other, manually configure all devices for 10
Mbps or 100 Mbps connections.
Transparency (PCI Version)
Transparency is only available when using Auto Negotiation mode; it is not
available in either of the two Force modes. When the McPC 10/100 is Auto
Negotiating, Transparency treats the connection between the two end devices as
if there were no media converters installed. For example, in a typical application
where two media converters are installed between two copper-based switches,
the twisted pair cables as well as the fiber cable are seen as a single entity.
Therefore, if a fault occurs on any segment between the two end devices, link
LEDs on the end devices will extinguish.
Transparency is available when the McPC 10/100 is operating in Auto Negotiation
mode. Therefore 6 (AN) must be ON and 5 (LFD), 7 (Force) and 8 (10 or 100)
must be OFF.
