1+1 Card Protection

As most of O9400R and O9500R's plug-in cards, two adjacent 8GESW cards can form a protection group and share the same configuration. The primary card is by default the working card, while the secondary card stands by. Working card failure will trigger instant card switching without any service interruption.
