Installation
Procedure
The following procedure will not disrupt normal operation of the router.
1. Install the supplied TPCP R1U3-B power supply frame(s).
The frames are shipped with the DC cables already connected.
The power supply frames should preferably be mounted in the same
equipment rack as the Trinix, but they may be mounted in an adjacent
rack if necessary. The cables provided for connection to the Trinix are
approximately nine feet (2.7 m) long.
No special ventilation spacing is needed for these frames since the
airflow is from front to back.
2. Connect the DC power cable(s) to the Trinix rear panel DC Input
connector(s).
See Table 2 for pinout information.
3. Connect the supplied AC power cords.
All LEDs on the front of the power supply array(s) should now be
green.The left LED of each supply monitors AC; the right LED monitors
DC.
4. Check the DC voltage now being provided at the Trinix “DC In”
connector(s). Voltage should be between 47.0 and 48.5 VDC.
5. 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.
• For DV-33128 and DV-33256 units, pull both internal power sup-
plies out a few inches. The router should remain powered up. Push
the internal supplies back into position.
• For DV-33512 units, first make sure that both power supply frames
are installed and powered on per the above procedure. Open the
main chassis door. Open the 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.
