Meraki MX75 Random reboots

[SeanW]

Just an open topic to owners of the MX75 router. I noticed that my MX75 would randomly stop passing traffic and at times would randomly reboot on its own. There is no real constant with this issue as its happened over multiple firmware releases, cable replacements, and UPSs updates. I was on the phone with support today about this issue and he stated there have been reports of MS75 owners having random issues the unit have two or three causes they are looking into. I'm ok with this (to a point), but I hadn't seen any buzz on the forums about this so I am just opening this topic to see if anyone else is having this issue as well, and if it was fixed what fixed it for you?

Hmmm I don't recall seeing this being a reoccurring issue. Have you tried an RMA to see if that resolves the problem for you. Usually with large scale issues a replacement program is launched and affected devices replaced.

My Eng wants to wait and see before setting up the RMA.

Not sure about the not passing traffic. 

There is however  a hardware defect that impacts some MX75's causing it to crash and reboot due to a kernel panic.

Support should be able to confirm whether that's occurring or not.

I had an MX75 replaced as the power socket was dodgy and touching the connector would reboot it.  The replacement was apparently one of the dodgy ones as it rebooted a few times, especially when both PoE ports were used.  However upgrading to MX19 fixed it and it has been stable since.

Funny enough 19.1.5 was my less stable FW.

I would suggest reach out to meraki support first and then go with RMA if required @SeanW
