Interfaces in power-down state

[NickVardy]

Hi all...I have a Palo Alto Active/Active pair and the HA3 link between them is down. Will PANOS then power-down all other physical interfaces when the HA3 link is down. Just looking for confirmation that this is expected behaviour or whether I have something more serious happening to this 3260. Any advise would be greatly appreciated

I do not believe it is expected behavior to admin down all interfaces because the HA3 link going down.  Not sure why you would see a "power down" vs an "admin down" for interfaces, so further investigation is warranted.
