NV8576
Figure 1-10, next page, shows the front of the NV8576.
The router is divided into three regions: upper, middle, and lower. The upper and lower regions
each have 32 slots for output cards and 32 slots for input cards. The NV8576 thus has a total of
64 output card slots and 64 inputs card slots. Cards in the lower region of the frame are installed
upside down (i.e., rotated 180° with respect to those in the upper region).
In the upper region, to the far right of the output card slots, are two monitor card slots. Similarly,
to the far right of the input card slots are two slots for the primary control card and the
secondary control card. The lower region has two more monitor card slots, at the far left of the
output cards. (The lower region does not have control cards.)
In the middle region are 10 slots for crosspoint cards. The middle 2 crosspoint card slots hold an
optional redundant crosspoint. The remaining 8 slots are for crosspoint cards.
