Configuration Tasks for Cards
Figure 3-3 Switchover with 1:2 NSC Redundancy
The logical slot number of the secondary card changes to 1, even though its physical slot number is 3.
Had the slot 5 failed rather than slot 1, the logical slot number of the secondary card would have
changed to 5.
Using 1:1 BSC Redundancy
You configure BSC protection using a pair of cards configured for 1:1 redundancy. After you configure
a redundant pair of BSCs, both cards reboot and return to operation with the same logical slot number.
The card LED displays green for the active card and yellow for the standby card.
