Fan Replacement
A fan failure is reported through the 2000NET module (if present) to the
Health Alarm Relay (2000T3 frame only) as a simple alarm closure. Using
the GUI you can select the frame status display to see Fan Status and click
on the suspect power supply sled to see which fan is reporting a failure (see
the 2000NET Network Interface Module Instruction Manual for details).
If a fan needs to be replaced, contact Grass Valley Customer Support to
order the appropriate replacement fan. To install a new fan, refer to
Figure 25 while performing the following:
1. Remove the frame front cover and slide the power supply sled out.
CAUTION Do not leave the 2000T3 front cover off the frame for extended periods when
the frame is powered.
2. Remove the appropriate connector (J4 or J3) from the power
distribution board.
3. Remove the fan assembly bracket by removing the three hex nuts and
interior star washers and lifting both fans from the sled.
4. Remove the two crosshead retainer screws from the corners of the fan
bracket for the defective fan.
5. Install the replacement fan, replace the fan assembly, and re-connect the
fan lead wires.
6. Install the power supply module in the frame and replace the front
cover.
