Remember back when Arizona was conducting their audit of the 2020 election and Maricopa counting was not turning over the routers and Republicans were having a breakdown over it.
I have 18 years of experience programming routers, specifically Cisco routers, I knew then the routers would show you nothing, I suspect the same thing in this case.
First, any configurations would be backed up somewhere just in case they had to be restored in a device, I would look there if any issues with the configurations were the problem.
Second, just because I’m somewhat a stickler for technical terms, they are not memory cards, memory cards are in every computer device and are volatile, if anything they are flash memory cards which likely hold the OS and configuration files for the device, both of which should be backed up in case a restore had to be done, that’s where I would look for anything.
State election law specifically states that serialized security tags be placed on machines after all testing is finished. Then the serial numbers are logged with the machines for audit. Copies of log show machines with no serial security number that were used in the election. Look for the video on Rumble.
