1) Is the 10BASE5/10BASE2 switch
set to the position corresponding to
the transmission medium actually
used?
1) Set the 10BASE5/10BASE2 switch
to the correct position.
2) Does the EXT.POWER LED turn on
?
2) Check whether or not the 12-VDC
power is supplied to the MAU power
supply terminals.
If the LED does not turn on even
when the 12-VDC power is
supplied,
→
replace the module.

10BASE5
1) Is the AUI cable connected between
the EN311 and the MAU ?
1) Verify the AUI cable connections
between the EN311 and MAU units.
2) Are the MAU units installed with a
spacing of 2.5 meters of coaxial
cable between units ?
2) Connect the MAU units correctly at
the marked sections of the coaxial
cable.
Marked section spacing: 2.5 meters
3) Does the MAU 12-VDC power
supply LED turn on ?
3) Replace the AUI cables and the
MAUs with other units to verify their
operation.
Supplement:
We recommend keeping spares on
hand to minimize the time required
determining the location of the fault
using the above procedure and to
minimize the time required for
recovery.
4) How long (in meters) are the AUI
cable ?
4) The maximum AUI cable length is
50 meters.
5) How long (in meters) are the coaxial
cable (i.e. segment lengths) ?
5) The maximum segment length for
10BASE5 cabling is 500 meters.

10BASE2
1) Is the coaxial cable connected to
the EN311 ?
1) Verify the AUI cable connections
between the EN311 and MAU units.
(These are the T-connector
connections.)
2) Is the spacing between stations
(nodes) as mounted at least 0.5
meter ?
2) Set the cable length so that the
mounting spacing is at least 0.5
meter.
3) How long (in meters) are the coaxial
cable (i.e. segment lengths) ?
3) The maximum segment length for
10BASE2 cabling is 185 meters.
