Manual N V8280 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 corresponding button (labeled 3) on the redundant crosspoint card. Immediately, the
redundant card takes over for that card. If the card is still powered up, its ‘Active’ LED turns off.
The redundant card’s active LED turns on, the button labeled 3 turns bright, and the ‘Standby’
button turns dim. All the other buttons go off.
The same applies to any of the other crosspoint cards.
You can place the redundant card in standby mode by pressing its ‘Standby’ button. You must
press the ‘Standby’ button before you can substitute the redundant card for another crosspoint
card.
 The normal card’s button has no function in an NV8280 and the label of that button has no
meaning in the NV8280.
