Troubleshooting
If you experience any of the following problems, follow the suggested actions.
Problem Corrective Actions
The cable connections are
poor.
Secure the cable connections.
The ERU was not detected.
Check the cable connections to make sure they are
secure.
Check to see if the cable is shorted. If it is, connect
another cable and check again.
Turn off the SOMAport and then turn it back on. ERU
detection is performed only when the SOMAport powers
on.
ATTENTION: To disconnect or reconnect the ERU, make
sure the SOMAport is off.
The signal is weak.
Reposition the ERU following the guidelines on page 21.
Try another ERU.
The total length of the coaxial
cable from the ERU to the
SOMAport is more than 45 m
(150 feet).
Check the connections and make sure they are secure.
Poor connections may be reported as excessive cable
length.
Reposition the ERU or the SOMAport to reduce the
amount of cable required.
