Re: [gentoo-user] UPS and serial or USB connections
One more update I guess. I couldn't get this to work with serial. The driver for this thing appears to be USB only. I might could get it to work in dumb mode but I don't want that anyway. So, if you buy a model similar to CyberPower 1350AVRLCD, don't depend on using serial connections. One other thing I don't like, it doesn't give me a internal temperature measurement. My old one did and I liked that. I actually had a external fan blowing air on the side where the vent holes are. It would be 100F even in a 70F room and it only 8 inches or so off the floor. That said, when in standby mode, it is cool to the touch so it seem to be a cool runner. It does have a fan that runs when it is running off the batteries tho. That makes me feel better. Thanks to all for the replies. Dale :-) :-) -- I am only responsible for what I said ... Not for what you understood or how you interpreted my words!

I still have both installed here. I'll get rid of the settings one and
see what happens. This may explain why I have two entries in the K menu
tho. There may be two versions installed, knowing me, I'm clicking on
the old one. lol

You're right, it is installed via the "tools" USE flag on nvidia-drivers now.

Actually, I believe with the newest nvidia-drivers packages
nvidia-settings is now part of that package so no need to emerge it

Anyway, when I connected it to the serial port, it would rather rudely cut off my puter after a couple minutes. Click, off. So, I hooked up the USB cable so that I could get back to going again. I'm going to have to google on how to get this to work with the serial cable. I found the settings for USB but nothing for this driver and a serial connection.

As someone who's done more electronics work than he ever should, any device that can suffer electrical damage simply by being plugged and unplugged from the thing it's supposed to be plugged into is a shoddy design and really should be in the bin. The only thing I ever found that was susceptible to this was ancient RS232 kit, and the cause was always inadequate shielding and isolation. In the last 10 years I only know of one product sold that has this problem and sadly that's the first run of the Raspberry Pi... You can safely plug and unplug VGA all day long and be hit by lightning more often than damage the monitor, repair techies have been doing it for years. VGA connectors are shrouded, you are virtually guaranteed an earth connection before any of the data pins make contact and you'll never have a situation where 25V is trying to shake hands with 5V (that was a major problem with RS232 stuff). Of course, there's no guarantee the picture will show on the screen if you hotplug VGA, but there's no inherent danger of damage either. -- Alan McKinnon alan.mckin...@gmail.com

I'm not saying the communication part should work when you plug up something, just that it shouldn't burn out a chip so that it never works again. It should at least have some forgiveness to the occasional accident of unplugging a cable.

The ethernet incident happened at work, which should be grounded, however it was in a cubicle... a cubicle that would give you the tingles if you touched its metallic edges. The TV was at my parents' house in the 1980's, an old home that certainly does not have grounded electrical outlets.

The strangest thing I fried via hotplug was an Ethernet card via cat5 cable insertion! It made a little electrical "pop" sound and that was the end of that.

I used to think the same way, until the risk turned out to be less negligible than I thought. It's entirely your choice whether you continue to take that risk, but I don't think it is fair to tell others it is safe to do so. -- Neil Bothwick She's fine, upstanding, and wonderful laying down. signature.asc Description: PGP signature

I must have hot plugged serial connections on Sun, Cisco and Intel boxes hundreds of times over the years and as far as i know have never seen a failure.

You were lucky, it's like forgetting to look when you cross the road. Getting away with it once doesn't mean it is safe.

Dale, A good way to test a new UPS is to use it to power a light and hook up the USB/Serial/... to a computer to see what information you can get out of it in the various "normal" situations of "plugged in" and "not plugged in" You don't need to reboot your machine for that. :) -- Joost

Then go back to serial and compare. If it does as you and me think it will, I'm going to stick with serial. If for no other reason than it frees up a USB port plus it is very hard to accidentally unplug my serial cable since it has the screws to hold it in. I still have not hooked this thing up yet.

I would be surprised if there is any difference. Usually the UPS just spits out a heartbeat of the same information every X seconds. I have a newer-model Cyberpower UPS and it works fine with NUT, so you're probably okay there. If you already have serial port set up and working then you've already got the hard part taken care of.

I haven't connected the UPS yet so I'm still using my old UPS and nut software. It has a Linux version on the CD but no mention of Gentoo, just rpm and deb. I tried to install this once before and I never got the software to work right. I think it was the init scripts that caused trouble. I looked at the nut website and it says the new UPS uses usbhid-ups which appears to need to be connected to the UPS by USB. I'll try the serial cable first, see what if anything it reports, then try USB and see if it reports the same thing. The old UPS uses powerpanel drivers within nut. That is sort of confusing since they call the Linux drivers the same as the windows software. Looks like I'm going to have to test this to see if it works or not. If it does, may need to report it to the people on the nut website. I would prefer serial if it works the same myself. Thanks much. Dale :-) :-) -- I am only responsible for what I said ...

Please excuse my brevity. Ooops. I thought I put the model. It's a CyberPower 1350AVR. My old UPS is a CyberPower 1250AVR but it is about 10 years old. I have one working plug left on the back of it. I literally wore the plugs out. lol According to the book, and the box, the new one uses powerpanel which is the same as I use on the old UPS. Since it uses the same drivers/software, I figure it will work like my old one does. Then again, this is newer so that's why I ask. My old one has LEDs on it where this one has a display with more info than my old one. http://www.newegg.com/Product/Product.aspx?Item=N82E16842102070 I don't yet have the UPS hooked up to the puter. I'm letting the battery charge overnight first. It says it is fully charged but still. Also, if it is going to blow up or something, I'd rather it do all that before I plug my rig up to it. o_O Thanks. Dale :-) :-) -- I am only responsible for what I said ...

[gentoo-user] UPS and serial or USB connections
Howdy, Newegg just had a sale on a really nice UPS. I got one. Anyway, it has both serial and USB connections. I have a question about these. I could use either one but not sure if it matters. Does the USB connection offer any additional features over the serial connection? I could use USB but would rather use serial since nothing else I have is serial but I have a bit of USB devices. Also, I never disconnect the serial cable from either the system or the UPS when either is in use. Sort of defeats the purpose I guess. Since it also has screws to make sure the serial cable doesn't come undone, the serial has one advantage. I'm not sure what would happen if it looses the connection all of a sudden. Does it do like NORAD and assume power is out? lol So, since I already have everything set up for serial connections, should I just keep using it or does the USB have more goodies? Thanks.
