Hello. How can I do configuration erase on single SP when it's origin is unknown, but full access to laboratory node exist, and service disruption is OK? Any magic with some jumpers?
Or the only way is to get remote access from Ciena to reset login|password on SP?
SP are NTK555AB type.
P.S. I know, I can mirror it with working SP in working shelf in working network, but I need to test SP in lab before I give it to customer. I have new SP from Ciena, it is SP2 type, and it can not be 1+1 with SP, right?
