Hello, I'm REALLY baffled at why a 2960X is not being added to our stack. I matched the new member's IOS to what the stack had. The sdm prefer settings match. The licenses both show lanbase. Yet, both the stack and and the new member show stack ports as down.
The funny thing is that when I plug the cable between the new member's own two stack ports. They show up but as soon as I connected it to the stack they go down.
The stack has two members. I am trying to add a third.
On start up, the new member shows this... but then the stack ports go down...

SM: Detected stack cables at PORT1 (only one cable was plugged in here but when I have both cables plugged in it shows detected at PORT1 and PORT2)
Waiting for Stack Master Election...
SM: Waiting for other switches in stack to boot...
Any ideas????
The new member never sees anyone and so becomes master.
