3.2 Replacing the Controller Card
The Controller card is located to the right of the power supply slots at the center of the frame. To replace the
card, proceed as follows:
1. Hook your finger through the opening at the top of the card. Pull gently until the card is released from the
rear connector, and then slide the card out of the frame.
NOTE: do not pull on the hinged control panel to remove the card.
2. Slide the new card into the controller slot, and push gently on the card edge to engage the rear
connectors. The connectors will not engage if the card is accidentally inserted in the wrong slot.
3.3 Replacing the Frame Ventilation Fan
In case of failure of the main cooling fan on the rear of the frame, replace it according to the following steps.
1. Procure a replacement fan. It is available from Grass Valley as part #1844-3000-200
2. Remove the defective fan from the frame:
•
Remove the two screws that secure the grill
and fan unit to the frame.
•
Retain the screws and grill, as they will be
used with the replacement fan.
•
Pull the unit away from the frame, and
disconnect the power feed by grasping the
connector and pulling straight out.
3. Install the replacement fan:
NOTE – Grass Valley uses two different fan units for this product.
While they are electrically equivalent, they have slightly different
dimensions. The fan is installed with two screws located on
opposite corners. The mounting plate has two sets of corner holes
– one to fit each of the available fan models. You will need to
install one corner screw and then try the diagonally opposite one
to see if it fits. If not, use the other pair of corners.
These two fan units also have different power connection
configurations. There are two identical power connectors
available on the frame into which you can plug the fan’s power
cable. When you install the fan, you will be able to tell which one
you should use.
•
Grasp the power connector attached to the fan assembly, and push it onto the appropriately-located
power outlet inside the cutout on the rear panel.
•
Use the two screws that were retained when the old fan was removed to install the new fan and grill.
See the note above.
