Installing Active Cards
The NV8288 and the NV8288-Plus feature several active cards that manage incoming signals, for-
warding of commands from the control system, signal switching, and the distribution of outgoing
signals. Each card is color-coded with an ejector lever that matches the color of the card guide into
which the card is installed in the router frame. For a description of each card, see
