Trinix — Installation and Service Manual 41
Installation Procedure - DV-33128 and DV-33256 Units
Note The following procedure should not cause any interruption to router opera-
tion. However, Grass Valley recommends that you perform this check when
the consequences of possible signal interruption are at a minimum.
7. Check the fail-over function of the new supply(s) by pulling the
internal power supplies out a few inches. The router should remain
powered up. Push the internal supplies back into position.
8. In some cases, the original Trinix system may have been supplied with
only one internal power supply. In this case, the SR/NR-33000’s sync
card jumper JN2 must be moved to the “AC” position for the alarm
system to operate properly.
Note For more information about this jumper, refer to the Power Supply Notes in
the Trinix Installation and Service manual, Hardware Installation section.
This completes the installation.
