Hi !
We have two 5500G-EI switches which are stacked via a XRN stacking cable. Both are running Firmware 3.03.01s168. We now have to update both to the newest firmware which at the moment is 03_03_02s168p07.
Does anyone know what the best strategy is for updating ?
Can we first update unit 2, restart it, and after the restart update unit 1 ? Does the stack work when they have different firmwares ? Or should we patch the cables from unit 2 to a third switch, so that unit 2 has no traffic ? Should we stop all traffic on both switches ?
I hope someone did this before.
Thanks in advance
Steve
