Cat 9300 Stack Power

[Hawk]

I have 6 Cat 9300's getting installed in one switch stack.  Each switch comes with it's own power supply but I was also given 2 extra power supplies (8 total).  The desired goal is to be able to have zero down time if a power supply in any of the 6 switches dies.  From what I learned there must be 2 power groups since each power group can only have 4 switches max.  Can anyone offer any advice on how I can configure things to accomplish the desired goal and if there are any considerations I should take before implementing the design?  thanks!

Have a look at figure-9 in this link. Depending on the power supplies you have in each switch and the power requirement per switch, you should be able to build 2 stacks with each stack having 3 switches in it.

in our environment we have stacks from 2 to 8 switches that are spaced out 1RU. We split them up in 2 and 3s. If we have 4 switches we connect 1/2, 3/4. If we have 5, then 1/2/3, 4/5, etc. We also split them up between different models, so P vs UXM vs U, etc. We could have sw1-2 UXMs connected, then sw3-4 Ps connected.
