5 Insert the optional redundant crosspoint cardset in crosspoint card slots 5 and 6. The redundant
crosspoint cardset can take over active control from any crosspoint card installed. For more
information, see Setting Redundant Crosspoint Switching on page 98
.
6 Insert the monitor cards in the two slots with blue and gray card guides located to the right of
the output cards. The card’s ejector lever is located at the bottom. Both monitor cards are the
same (EM0663). However, the output monitor is always in the outside position; the input mon-
itor is always in the inside position.
7 For each card, press the lever(s) inward, making sure each card is fully seated in its slot.
8 Reinstall and close the frame door after all cards have been installed. The door must be closed
for the router cooling system to work properly.
How to Install Active Cards in the NV8576 and NV8576-Plus
Important When you install cards in the upper bays, their ejector levers are down. Cards in
the lower bays slots are installed with their ejector levers up. Crosspoint cards
have two ejectors, one at the top and one at the bottom.
Caution Do not drop, roughly handle, or stack circuit boards. If you cannot easily insert or
remove a board, stop and contact Miranda Technical Support.
