Connecting the SmartNode to the power supply
1.
Insert the barrel-type connector of the AC power supply into the
12V DC, 1.0A
port (see
figure 2
on
page 17).
2.
Verify that the AC power cord included with your SmartNode is compatible with local standards. If it is
not, refer to chapter 5,
“Contacting Patton for assistance”
on page 36 to obtain a compatible power cord.
3.
Connect the male end of the AC power supply power cord to an appropriate AC power outlet, and verify
that the green
Power
LED is lit.
Using the ferrite clamp.
A ferrite clamp and two wire ties are included with all FXS units that have more than
four FXS ports (/8JS models).
Install the ferrite clamp on the 12V DC power cable two inches away from the edge of the chassis. There are
two options available for installing the ferrite clamp (see
Figure 7
below):
•
Option 1:
Wrap one wire tie around the power wire coming out of the end of the ferrite clamp.
Do not
tighten and secure the tie yet. Take the second wire tie and loop it through the first wire tie
and
through the
inside of the ferrite clamp. Then, you may tighten and secure both wire ties. Trim the ends off of the wire
ties once they are securely attached.
•
Option 2:
Loop a wire tie around the power wire coming out of the end of the ferrite clamp. Repeat the
process with the other wire tie on the other end of the clamp. Do not trim the end off of the wire ties.

External S-Bus power supply
Do not use an external power supply for ISDN terminals connected to the SmartNode. The SmartNode sup-
plies S-Bus line power to ISDN terminals connected to the BRI port, so external power supplies are not
required for the ISDN terminals.
The external power supply automatically adjusts to accept an
input voltage from 100 to 240 VAC (50/60 Hz).
Verify that the proper voltage is present before plugging the
power cord into the receptacle. Failure to do so could result in
equipment damage.
The ferrite clamp that is shipped with the unit must be used as
detailed in the following instructions in order to meet EMC
requirements.
