Swapping around a Card in a Multiviewer
Schedule this maintenance operation during off hours when the system is not in use if
possible as this procedure can cause multiviewer outage.
In an attempt to restore multiviewer operation and to perform fault isolation procedures,
you can
swap the position of cards around in the multiviewer’s frame to see if the problem
follows the card or to see if normal multiviewer operation can be restored.
To swap the position of a card around in the multiviewer, you must first identify two identical
cards installed in the multiviewer’s frame. For example, the model number marked on each
card’s ejector handle are the same. If two identical cards are found, eject both cards from the
multiviewer’s frame and exchange their positions within the frame before firmly reinserting the
cards into the frame. To RMA a defective card,
see Grass Valley Technical Support , on page 156 .
