still powered up, its ‘Active’ LED turns off and its button turns dim. The second card’s active LED
turns on and its button turns bright.

You can do the same kind of switching — possibly remotely — using the crosspoint card image
in the ‘Redundant Crosspoint’ page. These two figures show the different states of the cross-
point buttons:
NV8280 Switchover
The NV8280 has 10 crosspoint card slots. As viewed from the front of the router, slot 1 is on the
left and slot 10 is on the far right. The redundant crosspoint module occupies the two middle
slots, numbered 5 and 6:
The normal crosspoints are numbered 1–4 on the left and 7–10 on the right. Usually, the normal
crosspoint cards are active and their active LEDs are on and the redundant crosspoint card is in
standby mode, its ‘Active’ LED is off, and its ‘Standby’ button is bright.
If one of the normal cards (for instance, in slot 3) fails or you want to remove it from the frame,
press the button labeled 3 on the redundant crosspoint card. Immediately, the redundant card
takes over for the card in slot 3. If the card in slot 3 is still powered up, its ‘Active’ LED turns off.
