INITIAL START-UP PROCEDURE
NOTE
DURING SHIPPING, THE MODULES IN THE CHASSIS MAY BACK OUT OF
THEIR CONNECTORS. PRIOR TO BEGINNING THE STARTUP PROCEDURE,
OPEN THE FRONT DOOR, AND REMOVE AND RE-SEAT ALL FRONT PANEL
MODULES.
After the 9785 is installed and prior to being placed in service, a few basic adjustments and
measurements must be performed to ensure proper operation. The output power of the system should
be verified and adjusted if required, the output impedance of the transmitter must be adjusted to match
the actual impedance of the line, and the receiver must be adjusted for the actual receive signal level.
This section assumes that the equipment has been installed and configured for the required application
in accordance with Section 3 and paragraph 4.3. Note that the modules in the 9785 are not hot
pluggable. The power to the chassis must be turned off prior to removing in or installing any modules.
