Another ToughSwitch gave up this 'mour'ning....
4:30AM, stopped passing packets.
This is a new, *almost* in production site. Replacing the routerboard with an RB850Gx2.
Don't have the charge controller there yet, just the batteries. This site is a ~500ft DC run from reliable power. Using Landscape lighting cable to push a ~23.5V redundant supply of my own design down. Using Zener Diodes and 1Ohm resister to balance supplies, which accounts for the -.5V loss (which varies w/ load)
The WS-12-250-DC is telling me it's drawing ~36W with an input of 21.3V. So I'm losing a little over 2V across that 12 guage run, which lines up with the math's prediction pretty well. I Put a 100W load on this to test and it dropped to 18V.
Went with the 12 port unit because this site will be loaded up with 3-4 back/sidehauls and 5 APs, and will likely be the test site for Mimosa PtMP 'A' APs for us.
Sites' load is the WS, an AF5X, RB951G, an RACl and a RAC-PtMP. There is another AF5X powered down for the link that will close the ring here on the next sunny day.
This is another Router-on-a still site. RB951G is powered off port 12 of the switch.
