Battery backup and DVR

From: John Aldrich 
------------------------------------------------------
Is it safe to use a standard computer UPS with like a Dish DVR? I know 
you're not supposed to put certain other electronics like laser printers on 
a UPS. What about a DVR system? It's basically a computer system, right?

=============================================================== From: Cameron Kilgore ------------------------------------------------------ Yes, you can use a UPS on a DVR. Power outages will cause chunks of the filesystem (ext4, actually) to be scrapped. We've lost entire shows as a result. Go for a 300w+ model as those DVRs are MIPS and PowerPC based and draw a lot of power. Don't put other stuff on your UPS, especially sound systems and game consoles. That'll just give you less time to safely shut down the DVR. Is it safe to use a standard computer UPS with like a Dish DVR?

=============================================================== From: Bret McHone ------------------------------------------------------ The DVR should be fine on a UPS Correct me if I'm wrong people, but as I understand it the issue with printers on a UPS is the power consumption is really hard on them. It's basically like running a space heater off a UPS. -Bret

=============================================================== From: Cameron Kilgore ------------------------------------------------------ Only when printers are running (with this new age of always-on printers...). More time you have on that battery the better. 30 seconds is too little to shut down, 4 minutes is cutting it close, and if you can get 11 minutes out of your UPS, you must be some kind of a wizard.

=============================================================== From: Mike Harrison ------------------------------------------------------ That was true with laser printers. Ink-jets.. not so much.

=============================================================== From: Mike Harrison ------------------------------------------------------ Buy a real UPS. 15+ minutes is not hard. Just not cheap either. And I don't have one at home.. almost everything has gone laptop. I haven't turned on the "HTPC" (old desktop under TV) in a month. But I probably should have one on the media center/TV and such.. just to reduce spikes and glitches.

=============================================================== From: Dee Holtsclaw ------------------------------------------------------ Years ago we had a customer in Alabama do exactly that -- space heater plugged into the UPS. Their power went out one day while the heater was on and the UPS literally went up in flames. I asked the owner why the secretary plugged a heater into the UPS and he said, "Hell, I don't know!" No one was injured but the secretary in question had to go home and change clothes.

=============================================================== From: Rod-Lists ------------------------------------------------------ Must the same kind secretary that stapled 5 1/4 floppies to paper print outs. ----- Original Message ----- From: "Dee Holtsclaw" To: "CHUGALUG" Sent: Wednesday, February 16, 2011 9:26:06 AM GMT -05:00 US/Canada Eastern Subject: Re: [Chugalug] Battery backup and DVR Years ago we had a customer in Alabama do exactly that -- space heater plugged into the UPS.

=============================================================== From: Bret McHone ------------------------------------------------------ That's correct. I was referring to his statement: "I know you're not supposed to put certain other electronics like laser printers on a UPS" I have surge suppressors on my A/V equipment, but that's it. I used to have a UPS but it pissed me off by beeping every time there was a power flicker... which typically happened in the middle of the night. After the 3rd time I ended up giving it away and sleeping much better. Sure I may have to reprogram my VCR (yes, I still have one) when the power goes out but it's a small price to pay for sleeping better. Just as a side note, the UPS I had did not have the ability to turn off the buzzer. -Bret

=============================================================== From: Stephen Kraus ------------------------------------------------------ De-solder the buzzer That's correct.

=============================================================== From: Rod-Lists ------------------------------------------------------ A ham operator who worked with Marion County EMS told me a trick for spikes. Said to take your drop cords and put 3 loops in it . The coils magnetic fields suppress surges. Claimed the tip came Underwriters Labs I think. ----- Original Message ----- From: "Bret McHone" To: "CHUGALUG" Sent: Wednesday, February 16, 2011 9:32:49 AM GMT -05:00 US/Canada Eastern Subject: Re: [Chugalug] Battery backup and DVR That's correct.

=============================================================== From: John Aldrich ------------------------------------------------------ Thanks, guys... I was thinking it was probably safe. :-) Where I live in Cohutta/Varnell, if the wind blows, you get power glitches. In a thunderstorm you can expect a few momentary power outages (few seconds...long enough that you'd have to reprogram VCR and reset clocks, etc.) It's not as bad recently as it has been in the past, but it's still not what I"d call "reliable" power. :-)

=============================================================== From: John Aldrich ------------------------------------------------------ Interesting... is that 3 SEPARATE loops or 3 coils one on top of the other?

=============================================================== From: Rod-Lists ------------------------------------------------------ I think it was 3 close together on one line. I need to look KD4XV up and see how he is doing. ----- Original Message ----- From: "John Aldrich" To: "CHUGALUG" Sent: Wednesday, February 16, 2011 9:40:31 AM GMT -05:00 US/Canada Eastern Subject: Re: [Chugalug] Battery backup and DVR Interesting... is that 3 SEPARATE loops or 3 coils one on top of the other?

=============================================================== From: Cameron Kilgore ------------------------------------------------------ Looped like the magnet you made in science class.

=============================================================== From: Dave Brockman ------------------------------------------------------ -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 It should be fine. You don't want to put your laser printer on the UPS because when it heats up the drum it spikes it's draw a bit. And seriously, if the power goes out, do you need the printer on? :) Regards, dtb -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk1b9QAACgkQABP1RO+tr2TprACfRPXKkeJVQRjiUo2eIxUeAHql TmMAoMBvJ/CWyfwaILlYzImvt/sM0OAf =rmnX -----END PGP SIGNATURE-----

=============================================================== From: Mike Harrison ------------------------------------------------------ It's probably un-pluggable.. Steven is a (good) example why a license should be required for buying a soldering iron. But like most Linux centric guys, he goes straight to the nitty gritty solution.

=============================================================== From: Cameron Kilgore ------------------------------------------------------ I just live with the buzzer. It's there for a reason, and that's to tell you the UPS has activated.

=============================================================== From: Dee Holtsclaw ------------------------------------------------------ My standard response is: "You know a hammer will fix that ..." I wouldn't remove the buzzer -- but I might consider desoldering one leg and installing a switch in series with it.

=============================================================== From: wes ------------------------------------------------------ maybe a little resistor to lower the volume. -wes

=============================================================== From: Chad Smith ------------------------------------------------------ Couldn't you hook it up to some sort of stereo speakers with volume control - and maybe install a small embedded linux Ogg player - or a system to remotely access a networked media server (perhaps one being protected by the UPS itself) to play pleasant music or ambient noise that wouldn't wake you up, but still alert you? Or... IDK - take it out of your bedroom.... - Chad W Smith "I like a man who's middle name is W." - President George W. Bush - February 10, 2003 bit.ly/gwb-dubya

=============================================================== From: flushy ------------------------------------------------------ I get about an hour off my $60 dollar APC UPS. Of course, it's just powering a linksys router, an atom nettops box, and a cable modem. --b
