Installing Active Cards
The NV7512 router features several active cards that manage incoming signals, forward control
system commands, perform signal switching, and distribute outgoing signals. Cards slide into a
card guide such that the connectors on the rear of the card interface with the motherboard. Each
card has two levers—one at the top and one at the bottom—that help eject the card for easy
removal. For a description of each card, see
Active Cards on page 20. Cards are held in place by
pressure from the closed router door against the metal plate on the front of each card. All cards can
be inserted and removed with the power on.
Installing I/O, Control, Crosspoint and Monitor Cards
Different combinations of input cards and output cards can be installed in a single router frame. For
example, four AES synchronous input cards, 8 MADI input cards and four analog input cards. Be
sure to install the appropriate input cards and output cards, and the correct number needed for your
switching configuration. For information about signal types managed, see
Signal Types and Rates
on page 4. For information on each type of input card and output card available, see Input Cards on
page 20 and Output Cards on page 26.
Input and output cards must match the backplane installed for that slot. For example, if the back-
plane installed for Slot 1 contains DIN 1.0/2.3 connectors for unbalanced AES signals, then the
input card installed in Slot 1 must support unbalanced AES signals. For more information, see
Backplanes on page 12.
If only one control card is being installed, an optional systems clock generator card may be
installed to ensure system clock information backup. See
Installing a Systems Clock Generator
(Optional) on page 43.
All cards can be inserted and removed with the power on.
How to install active cards
1 Facing the front of the router (door open), locate the control, input, crosspoint, and output card
slots.
2 Insert each card into the router frame by sliding it into a card guide. On all cards, the metal plate
on the front of the card should be facing outward.
Insert the card in designated slots only, as follows (see Figure 2-6 on page 43):
• Insert control cards in the two right-most upper bay slots. Locking levers are located at the
top and bottom of each card.
• Insert input cards in the lower bay slots. Locking levers are located at the top and bottom of
each card.
• Insert output cards in the upper bay slots. Locking levers are located at the top and bottom
of each card.
Caution Do not drop, roughly handle, or stack active cards. If a card does not remove
or insert easily, stop installation activities and contact NVISION Technical
Support (see
Technical Support Contact Information on page iii).
