Trinix — Installation and Service Manual

Section 3 — Installation for Legacy Frames

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

Connect the AC power cords for the external A/B power supplies and
the external C/D power supplies.

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

Restore power to the internal power supplies.

Check the DC voltage now being provided at the Trinix “DC In”
connector(s). Voltage should be between 47 and 52 VDC. If not, contact
Technical Support.

At an appropriate time, check the fail-over function of the new
supplies. This procedure should not cause any interruption to router
operation. However, Grass Valley recommends that you perform this
check when the consequences of possible signal interruption are at a
minimum.

•

First make sure that both external power supply frames are
installed and powered on per the above procedure. Open the main
chassis door. Open the Trinix power supply chassis and pull the A
and B supplies out a few inches. The router should remain powered
up. Replace the A and B supplies. Pull the C and D supplies; the
router should remain powered. Replace the C and D supplies.

In some cases, the original system may have been supplied with a total
of only two internal power supplies. In this case, the RP-33500 512 x 512
Rear Panel’s card jumper JN1 must now be moved to the “AC”
position. This step ensures that the alarm system will 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.
