How to Install a Backplane
1 Facing the rear of the router, locate the slot into which a backplane is to be installed. If you are
reconfiguring the router, relocate backplanes as needed.
2 Insert the new backplane into the frame being sure to align the printed circuit board with the
stamped guides in the frame. Use gentle pressure at the top of the backplane to ensure the back-
plane connector is fully mated with the motherboard.
3 Tighten the two spring-loaded backplane retention screws.
4 To maintain proper airflow for cooling, all backplane slots must have a backplane or cover plate
installed.
Installing Cards
Routers in the NV8500 family use a number of active cards that manage incoming signals, forward-
ing of control system commands, signal switching, and distribution of outgoing signals. Cards slide
into a card guide in such a way that the connectors on the rear of the card interface with the mother-
board. 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 Active Cards
on
page 37.
For each card installed, a corresponding backplane must also be installed. The backplane contains
the connectors that connect to cabling for the receiving and distribution of signals. (See Backplanes
on page 29.) As you install cards, check the corresponding backplane. If the red LED on the back-
plane lights, the card and backplane do not match. If the green LED on the backplane lights, the
card and backplane are a correcting pairing. (See Indicator LEDs
on page 101.)
