Installing Monitor Backplanes and Cards
Installing Monitor Backplanes and Cards
NV8500 series routers ship with all cards and backplanes installed. You might have occasion to
install new cards or re-install existing cards.
You install monitor cards the same way you install any I/O card. See Chapter 2, Inputs and
Outputs on page 21 for installation instructions.
For the NV8280, NV8576, and NV8576-Plus, the same monitor card is installed for both inputs
and outputs. It is the slot in which the card is installed that determines whether the card moni-
tors outputs or inputs.

the lower output bay. (See Figure 1-10 on page 14.)

In the upper region, the card’s ejector lever is at the bottom. In the lower region, the card is
inverted, and the card’s ejector lever is at the top.
Insert the output monitor cards in the outermost slots of their respective bays. Insert the
input monitor cards in the slots next to the output monitor cards.
