Axiom 9 freezing on power on

[OTR]

Hi, I’ve had an issue a several times now with my screen freezing up when I power the system on. The only way to clear it is to cut power at the main switch and reboot everything. It is running the latest software 3.4.66. I have two Axiom 9s, Quantum Radar, CP470, HS5, EV200, RAY52 VHF. Everything is essentially brand new except the 470 and the EV200 which I carried over from my old rig. I checked online for updates again today so I know everything else is current too. The one that freezes is the slave. The data master display never does it (although it did crash and reboot once today, probably unrelated to this issue I’m more concerned about).

I’m starting to wonder if it’s something to do with the HS5 or something else on the network. I have these set to power up with all the other electronics when I flip a switch at my helm. I assume this should be okay to do? Or should I have the HS5 on a separate switch and power it on first? Is this a known issue? Any solutions? I am very hesitant to do a factory reset since I’ve spent a lot of time setting the pages how I want them. Can I reset the slave without losing all the pages?
