I'm going to need the stack mainly for redundancy purposes (e.g. multi chassis LAGS).
Actually I've already updated all the devices to the latest firmware version but reading the docs I was wondering about the firmware update when the stack will be in production.
In fact it seems to me that in this case I will need to update one of the two images on all the stack members and than reboot all the members simultaneusly (and so causing service disruption!)
Is that true? There is a way to do a conservative stack upgrade?
I'm also going to buy a M5300 stack, and I was wondering if it will have the same problem.
That's correct! We apologize but that is working as design. I may suggest you to upgrade the firmware after business hours. Just in case you still need assistance, please let us know.

Once the firmware upgrade process has been started in a stack it will automatically reboot the switches for a while as it needs to re-elect the management and the stack members then boot up with the firmware installed. You can manually upgrade the switches one by one if you doesn't want to disrupt the whole stack. As per standalone firmware upgrade, it will not reboot the switch by itself as we can have 2 firmware images installed on the switch. Once you activate the new image to be active then that's the only time that it will require a reboot.

Hi John,
thank for the answer!
If I understand correctly even in the case of standalone upgrade after I have upgraded all the active images I need to reboot the whole stack at the same time otherwise I will have switches with incactivce state.
Is that right?
To be honest for this type of switch would be great to be able tu run a non disruptive upgrade, because I think that 90% of 8x8F and 12x12F customers are using a stack of two for redundancy as Top of the rack switch!
