btw there is already a dedicated line that I ran to the door computer. It's coming down from the ceiling above it. It's a blue cable, it just needs to be crimped. I was confused about what people meant by "dedicated" and thought they meant that the ceiling cable wasn't dedicated enough but then I saw that it isn't actually in use yet. The other end is the one that comes through the TIL room upstairs and goes above a wooden beam and plugs into the (non-shitty) switch mounted on a wooden beam above the public terminals.

i didn't install the 12v ups, yet, as the switch is 5v/3a
might be easier to back the whole circuit w/ a 120v ups as the problem is usually it getting unplugged.

the outlet is about 6ft on the wall & i was thinking we could install another outlet directly underneath w/o too much cutting.
incidentally, this is also the circuit that aqua viva uses to heat water & may continue to get tripped.

One of these badboys is all we need assuming we can keep a lead acid battery charged nearby https://www.amazon.com/DROK-Converter-Step-down-Transformer-Regulator/dp/B00C66B3PM/

If there's already a wire nest we could also deadbug a TO-220 package regulator into the fold.

What is the input voltage to the switch, 7.5V?  I need to order some switching regulators, can get an extra one that meets power needs of switch if we want to run from lead acid battery.  Alternately could boost from a regular USB battery bank that stays plugged into a wall wart to top off.

i think those (myself included) who want a dedicated line should run it at our earliest convenience

as to the power, wouldn't a ups be nice for between the wall outlet & door system?

last week I power-cycled the front door beaglebone black and its ethernet interface started working again.  Before I did that, the ethernet port was not getting a link at all, even when connected to a known good cable.

After the power cycle, its ethernet worked, but since I had not power cycled the USB hub and magstripe reader, it was giving errors until i rebooted it, and then it worked properly.

well i spoke too soon, it just came back online by itself.

The front door computer has a battery backup so that it can keep working even if the rest of the world disappears.  But we won't find out about it losing power unless it has a connection to the internet.

presently it goes through at least one hub on the way back to the server area, and that hub does not have a battery backup, and apparently gets unplugged regularly.

I still think we should have a dedicated CAT5 ethernet run from the front door to the server rack, since this is such important infrastructure.

thank you

Eh it's pretty far and going through a floor and the timeless infinite
light room. Let's not run that again if we can help it. I'll go check on it
in a bit. We could do a new run up to the public terminals and just join it
to the existing wire from the doorputer to get a dedicated run.

the front door computer is still not on the network as far as i can tell.

i haven't seen sudobot talk (in irc) about the front door since 9/13

i'm assuming people are still able to use their cards to get in?

we really need a dedicated CAT5 cable run from the front door computer to
the server rack in sudoroom.  No hubs or switches along the way.

reseated ethernet connections
the bbb's ethernet port leds blink

i noticed the power cord is miserably connected to the wall & the ethernet
run takes an unfortunate journey under the rug between sudo to stage door

i'm guessing people are still using their cards to get in, but if there's
a problem, for example if it gets unplugged from electricity and switches
to battery backup, we will not be notified and will not know to send
help.

can someone take a look at the ethernet situation over there and see why
it's not getting back to the main network?
