Thats correct. Only the current master has a white light. The warm spare is orange. The switches have a white light while the warm spare is powered off but shortly after powering on the warm spare the switches turn orange, even though the master doesnt change. the warm spare doesnt become master. theres no indication of a dual-master scenario. Sometimes the switches go to white but wont stay that way, they'll go back to orange after a short time.

Hi PhilipDAth, Good point, I should have elaborated on how the two MX's are connected. I have two MS225 switches. Each MX64 has a trunk to each switch. +-----+

+------+ +------+ Firmware versions are consistent across all devices. The MX64s are running 12.26 and the MS225s are running 9.32. Config is 'up to date'. There's a 4G usb dongle on-site that was used while we waited for the wired internet to be delivered. At the moment its only got a prepaid sim which is out of credit so no data service available. The second internet isnt the concern, the concern is the behaviour when the spare doesnt have internet. I can reproduce the problem in a lab at head office which has the exact same hardware. As soon as I pull the internet from the warm spare the network falls to pieces and I dont understand why.

I have a pair of MX64s in NAT mode with one acting as a warm spare. The problem i have is when the internet service for this remote office was ordered it has been delivered as a single copper hand-off requiring PPPoE auth. When the internet service is connected to the Master MX64 with the 'warm spare' NOT connected to the internet the network is extremely unstable. Downstream devices are disconnected from the Meraki cloud, and then restablish connection, and then fall off again. As soon as i pull the power out of the warm spare device the network becomes stable. Is this expected behaviour? I know it doesnt make a whole lot of sense having a warm spare which doesnt have an internet link because it cant really automatically failover. I figured if theres a failure I'll just have to talk the people on-site through connecting the internet cable to the warm spare and they'll be up and running again. Can anyone shed any light on this?
