I recently purchased a 5540 pair and plan on deploying them in the next few months swapping out a 5250 pair. I'm curious if anyone has worked with the 5500s yet, or even PANOS 12.1?
Any comments or feedback you might have based on what you've seen so far.

One thing that we already provided feedback to the account team the documentation isn't exactly obvious. When we tried getting the 5540s up, we couldn't get management online. Apparently there are "logging" interfaces and "management" interfaces. We had initially used the SFP ports on the left of slot 7, but that didn't get management to come up. When we moved the SFP to the right bank of ports the management interfaces came up on the 2 boxes.
So there's a little "ism" that isn't directly obvious for anyone trying to get these new hardware types online.

Hello @Brandon_Wertz
I haven't work yet with PA-5500 series but since you have a pair and you think to replace a PA-5250 pair, I advice to look carefully on High Availability and Clustering part. The PA-5500 series have only HSCI interface and according with official documentation (datasheet) HA active-passive is not supported yet.
In PAN-OS 12.1 for PA-5500 series there is a new feature called NGFW Clustering.

@CosminM -- Yeah I noticed that. Thanks for the heads up. I hear there might be some good news on that front.
