[Mesh] Trouble with meraki board

[Marc Juul]

Hi Daphne.

The serial tty will show up in dmesg as soon as you plug in the usb serial
adapter. It does not know about the meraki board. The meraki board needs 12
volts or 15 volts DC. I have not tried powering it with PeE, but be aware
that only one of the two ethernet ports takes PoE. Try to find a 800 mA or
more 12 volt power supply and use that to power it on.

If you can't get it to work, I will be back at mesh hacknights the coming
Tuesday and Thursday to help troubleshoot.
