Hi All,
I need to setup an 8-member Catalyst 9300 switch stack that will use Stackpower. I'm aware that a Stackpower ring is limited to 4-member switches, so in my scenario I need to configure two Stackpower rings, however, I cant find any clear cabling guides to achieve this. Does anyone have an example cabling diagram for this please?
Thanks

Also, please remember that power stacking is not a UPS solution and does not protect you against power failure to the whole stack. It only protects you if someone accidentally unplugs one or 2 of the switches from the wall outlet or PDU.

Hi
Just an option , instead of trying an unsupported design why not stack power in star topology then you can have all 8
A switch power stack can include a maximum of four switches in a ring topology and eight switches in
a star topology.

Hi Mark,
Thanks for the response, however, doesn't a star topology require an RPS? If so, I dont have one of these available so I'm limited to forming stack power rings.
Thanks

Hi,
That is correct. If you had an RPS, you could connect up to 9 switches to it, but since you don't have one you are limited to a ring topology using power staking cables.

I agree with Mark. There should be 2 sets of 4.

Hi Reza,
Do you mean that in the absence of an XPS, 2 powerstacks of 4x 9300s within a datastack of 8x 9300s is a valid configuration? I believe this is the case, but I couldn't find much documentation around it or any user feedback. I really would like to exceed 4 stack members, but the XPS doesn't appeal much.
Regards
James.
