[AusNOG] Cisco 6500 redundant supervisor

[Peter Tonoli]

Hi Dylan, 


It *shouldn't*, but in rare cases, it can. There have been versions of IOS with known crashes of the running supervisor crashing when a 2nd sup has been installed - I've seen it happen once. I'd schedule the install out of hours. 


The usual caveat applies with cards being installed incorrectly, too quickly / slowly. 


Cheers, 
Peter.
