• In
Force 100 mode
, the McPC 10/100 acts as a 100Base-TX to
100Base-SX multi-mode or 100Base-FX single-mode fiber media
converter; 10 Mbps signals are not accepted.
To enable Force 100 mode, set switch
7
to the
ON
position, with
switches
6
and
8
in the
OFF
position.
There is no auto-negotiation in either of the Force modes
Auto-Negotiation and the McPC 10/100
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:
A)
Configuring every device in the media conversion for Auto-
Negotiation.
B)
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.
