The ohmmeter must measure Open to ground before plugging it into
the shielded RJ-45 coupler on the end of the NTMF94EA.
If the ohmmeter does not measure Open, install the unshielded
RJ-45 coupler (provided) on the end of the NTMF94EA to prevent
ground loops to external LAN equipment.
WARNING
The serial maintenance ports on the faceplate connector
and the DB-9 female connector of the NTMF9DA cable
assembly are identical. Do not connect a serial device
to both access points simultaneously. This results
in incorrect and unpredictable operation of the Voice
Gateway Media Card.
