Monitoring Power Supplies and Fans
If the 2000NET Network Interface Module is installed, power supply and
fan monitoring is available through the frame health relay (2000T3 frame
only) and the remote control and monitoring system (GUI).
CAUTION Always verify that the power supplies are fully seated in their slots. The
locking pin on the supply handle should lock into the hole on the side of the
frame (see
Figure 23 ).

Troubleshooting
Use the following sequence of simple checks in the event of problems with
your 2000 Series power supply. If the problem cannot be determined,
contact your Grass Valley distributor or the Grass Valley Customer Sup-
port.
CAUTION Equipment may contain static-sensitive components. Use properly grounded
test equipment and work only in static protected areas to avoid damage.
1. Check Associated Equipment.
Before proceeding with troubleshooting, check that the equipment
connected to the 2000 Series frame is operating correctly. Check all
input signals to the frame to be sure they are present; make sure cables
are not defective and are properly connected.
2. Check Power.
Check the LEDs on the power supply front panel. The two green LEDs
should be illuminated when power is applied. If not, check that the
power cable is connected to a source of power. Verify whether there is
power available at the power main. If any LED still does not light, use
a voltmeter to verify that the +24V is truly not present at the associated
testpoint (checking for a failed LED). If the voltage does not register on
the testpoint (see
Figure 24 ), replace the power supply with a
known-good supply.
