@voltronic Mine works well, also, and I locked it down. I just didn't trust that after several years of no updates from Actiontec (all the while seeing security updates to my Linux servers on a near daily basis), that a hole hadn't been opened somewhere.
Now, the Actiontec is buried deep in my network with forwarded packets sniffed to and from :)
@JWilliams it's also the reason I'm in the process of swapping D-Link switches out for Ubiquiti equipment. Nothing is perfect, but I'll take actively supported and updated equipment over the "buy and forget" stuff from most vendors any day.
@JWilliams this point:
"ISPs do not replace equipment on a customer’s property when that equipment is no longer supported by the manufacturer or vendor."
...was a big reason why I went from using a Linux-based Actiontec FIOS router that hadn't seen any available updates in years to using OpenBSD-based firewalls and routers at the network border.

"Legitimate user masquerade is the primary method by which these cyber actors exploit targeted network devices. In some cases, the actors use brute-force attacks to obtain Telnet and SSH login credentials. However, for the most part, cyber actors are able to easily obtain legitimate credentials, which they then use to access routers"

@Spartan All good advice. The batteries in question are AGM and gel cell types (two separate power supplies), and I have a tray ready.
The chargers/power supply boards are Altronix current limited systems designed for fire and burglar alarm duty with gel/agm backups, so overcharging is not much of a danger.
A little project nearing completion: redundant 26V battery backup power supply for a couple of 48-port Ubiquiti switches (plus a redundant 54V battery backup power supply for couple of POE-powered Ubiquiti access points).
Should provide upwards of 24 hours of battery backup.
One highlight of yesterday's #MarchforScience : the hardcore religious guy standing on the corner, yelling at marchers that they were all headed for eternal damnation.
Just wouldn't have been the same without that.
Really kind of hope the "limited strike" people won out.
@ucantstop_me Cool. Happy Friday!
@ucantstop_me To be clear, my "tag" post before wasn't intended as an admonishment. This is interesting stuff, and it should have wider exposure!

The FDA has approved an AI diagnostic device that can detect a form of eye disease by looking at photos of the retina — and doesn’t need a specialized doctor. #CoSoScience https://www.theverge.com/2018/4/11/17224984/artificial-intelligence-idxdr-fda-eye-disease-diabetic-rethinopathy

Do you know what Bismuth is?
Bismuth is a chemical element with symbol Bi and atomic number 83.
It's beautiful and it's boiling point is low enough that you can grow bismuth crystals on your stove! not sure if the crystals are the same as elemental bismuth but it's still pretty
many ways to grow Bismuth
