I have a 4 switch data stack using 3750-X switches. They are configured for Power Sharing but there are two PowerStacks. One PowerStack only has switch 2 in it. The other has the remaining 3 switches. Is this a problem? Will power sharing work should any of the 4 switches loose  power?  Here is the config:

 

nwcds-3750xstack#sho stack-power
Power stack name: Powerstack-2
Stack mode: Power sharing
Stack topology: Ring
Switch 2:
Power budget: 703

High port priority value: 12
Switch priority value: 3
Port 1 status: Connected
Port 2 status: Connected
Neighbor on port 1: e4c7.22e1.b200

It should work fine.  With power stacking, as long you are connected to only one other switch, the power redundancy would work fine in case of a power failure to one of them. This is assuming that the power supply has enough wattage to handle 2 switches.
