To connect your recorder to a UPS, simply plug the UPS into an AC socket, and
plug the recorder into the UPS using the power cords provided. If you use an
approved UPS, also connect the UPS to one of the recorder’s USB connectors on
the rear panel using the cable provided with the UPS. This communication link
will perform a safe shutdown when necessary, and also allow the recorder to
notify you (by display and optionally by email) if there is a power problem. The
NexLog 740 and NexLog 840 recorders are supplied with dual redundant power
supplies. To preserve redundancy, it is acceptable to use a separate UPS with
each power cord from the recorder.
2.4.7. Before You Connect Audio Signals to the Recorder...
Before you connect the telephone lines, radio outputs, or other signals to be
tapped and recorded, set the recorder’s internal clock, date, time zone, and
channel names. If you are installing new software on a currently operating
recorder, disconnect the audio inputs until you have restored the configuration
of the recorder, including channel selection and time zone. The reason for this is
that the recorder will begin recording as soon as it detects an input signal. Calls
with the wrong time, date, and time zone may get recorded and will likely
remain on the recorder for a long time. This might be confusing later when you
search, filter, and archive calls. Refer to Section 3 of this document for
configuration information including Date and Time settings.
