Installation Procedure - DV-33128 and DV-33256 Units

f.

All connections to the router itself are now done. Double check all
wiring.

3.

Connect the AC power cords to the external power supplies.

4.

At the front of the external power supply chassis, screw in each supply.
Verify that the two LEDs on the front of each supply are green (AC
good/DC good), and that the fans all rotate.

5.

Restore power to the Trinix internal power supplies.

6.

Check the DC voltage now being provided at the Trinix “DC In”
connectors. Voltage should be between 47 and 48.5 VDC. If not, contact
Thomson Grass Valley Technical Support.

7.

Check the fail-over function of the new supply(s).This procedure
should not cause any interruption to router operation. However,
Thomson Grass Valley recommends that you perform this check when
the consequences of possible signal interruption are at a minimum.

a.

Pull 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
a total of 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 redundant power supply
notes in the Installation section of the Trinix manual.

This completes the installation.
