Token Ring Speed Settings
The router will
autosense
the Token Ring speed of 4MHz or
16MHz. This is the default setting.
In exceptional circumstances it may be necessary to manually
set the Token Ring speed.
To do this, un-clip the casing of the unit (ensuring that it is
disconnected from the power supply). The Token Ring speed
pins are located on the circuit board and are easily identified by
a red jumper. The layout is shown in the diagram below.
The red jumper will be over the Auto pin only, enabling the
router to select 16MHz or 4MHz as required. To set one speed
only, remove the jumper and replace it over the Auto pin
and
the pin of the speed you wish to set, as shown in the diagrams
below.
After the setting has been selected, replace the casing again
and the router will operate only to the speed selected.
