Hello, I am trying to understand the proper method for replacing slot #1 (<-- specifically) in an XOS stack. Example: (2) 460-48p switches, Master & Backup running 126.96.36.199 p1-3. Slot #1 needs to be replaced. Prep replacement with proper code and partitions enable stacking protocol enhanced. Remove existing switch 1, switch 2 becomes master. Install new switch 1, enable stacking node-address (new node's info), configure stacking node-address (new node's info) slot-number 1, synchronize stacking node-address (new node's info). Reboot node-address (new node's info). New node comes back up (see vlan synch, fdb, acl synching). Stack looks okay for now. Issue command configure stacking mac address and reboot the stack. At this point new slot 1 becomes master and gets stuck at enter passphrase. And the switch reboots. The only way we have found to resolve this is to then config none on all switches in the stack, and load script of the original config. This is time consuming and not the preferred method I can guess.This has happened at several locations that we've had to replace slot #1 in particular. So it's not just one example. What would be the best method for success for replacing slot #1 in XOS?
