FIBER OPTIC CONVERTERS I & II
3.4 Config Switch
The Config switch on a Converter’s
front panel is used to configure the
RJ-45 copper connectors for the
different applications mentioned
in the previous section, RJ-45
Connectors. Figure 3-5 shows the
functions of different positions of
the switch.
Phantom
refers to the phantom
voltage that is required from the
Converter when it is connected
directly to a station port on a MAU,
such as in a lobe extension
application. When the switch is on
the
On
position, phantom voltage
is presented.
The
Station
switch is used in lobe-
extension applications when the
converter is on the station end of the
lobe. When the
Station
switch is in
the
On
position, phantom voltage
from the station is detected by the
converter.
NOTE
The converter will not
operate if Switch 3
(Phantom) and Switch 4
(Station) are in the On
position at the same time.
Specific instructions for setting the
Config Switch are given in Chapter 4.
