I have 3rd party support on my M1000e chassis, and I have a pair of M8024-K switches that are stacked. One has failed (DMA errors, and reboots, looping...) I'm being shipped a new switch blade. Question: What is involved in a replacement? The master "Mgmt Switch" is still up and healthy, and holds a good config. I'm guessing such as:
1.) Switch is inserted, and an automatic firmware upgrade is done, to match the Master. What if a downgrade is necessary to bring the OS of the new switch down to the level of the current Master? This will automatically reboot the switch (or the whole stack) when complete?
2.)the config will then be sync'ed after the OS is at the proper level, I'm thinking. --this will require a second reboot (of the new switch, or the whole stack)?
We're just wondering how much downtime may be needed in order to get the new switch inserted, get the OS sync'ed and the config sync'ed....
