| hmw_metalab | Now, that I fixed my N900, I am compiling a list of information, downloads and hits on my personal web site. What is the situation about copyright regarding firmware images and other downloads? I would like to mirror everything, I found. | 01:42 |
|---|---|---|
| hmw_metalab | s/hits/hints | 01:42 |
| brolin_empey | hmw_metalab: IANAL but I do not think you have to worry about mirroring Maemo stuff considering that it is aged close to a decade. | 10:14 |
| hmw_metalab | Thanks, I guessed so. I just wanted to hear, if there have been any issues or not. | 10:16 |
| hmw_metalab | That thing still rocks. | 10:17 |
| timeless | anyone here deal w/ rack mount UPS systems? | 19:09 |
| sixwheeledbeast | in what way? | 19:16 |
| timeless | we have one and one of its batteries failed | 19:17 |
| timeless | so i figured i'd ask some basic questions | 19:17 |
| timeless | but the web has kind of given me the answers | 19:17 |
| timeless | namely: (1) don't store UPS batteries w/o plugging them in, it's bad for their health -- I think I knew that at one point but long since forgot | 19:17 |
| sixwheeledbeast | ask away i deal with that type of stuff yea | 19:18 |
| KotCzarny | ya, leadacid batteries are selfdischarging | 19:18 |
| KotCzarny | and they have best life when being fully charged | 19:18 |
| KotCzarny | basically same as car accu | 19:18 |
| KotCzarny | they CAN be stored, but you should be charging them to full once a month | 19:20 |
| timeless | are all battery packs basically rebuilt/recycled exteriors w/ fresh batteries? | 19:21 |
| KotCzarny | define 'all battery packs' | 19:21 |
| timeless | https://www.amazon.ca/Smart-UPS-SUA3000RM2U-Battery-Cartridge/dp/B00C80UTSS | 19:21 |
| timeless | "battery cartridge"? | 19:22 |
| KotCzarny | hehe | 19:22 |
| timeless | i.e. a pluggable thing that someone adds into a rack mount ups? | 19:22 |
| KotCzarny | same as disk drive cartdridges | 19:22 |
| KotCzarny | you can try fiddling etc, but in pro world they just replace whole modules | 19:23 |
| timeless | i'm not interested in fiddling | 19:23 |
| timeless | just trying to get a sense of whether i'm almost always getting a "rebuilt" thing | 19:23 |
| timeless | "refurbished" | 19:23 |
| KotCzarny | '1 new' | 19:24 |
| KotCzarny | there is a chance it's some kind of noname replacement | 19:26 |
| bencoh | a recycled exterior isn't so muchof an issue. the real problem with noname is that you cannot really trust them regarding battery capacity / state | 19:33 |
| sixwheeledbeast | Mostly they are designed for SLA aka AGM batteries, these are similar tech to flooded car batteries but are designed for an application. | 19:36 |
| sixwheeledbeast | In a UPS you would have 12V C20 batteries these have an expected life of 5 years in float applications like a UPS. They are generally packaged for your UPS into "cartridges" | 19:38 |
| bencoh | talking about that, I wonder if/when DC power input will ever become standard on servers | 19:38 |
| bencoh | the whole AC/DC/AC/DC thing with UPS is just plain silly | 19:39 |
| timeless | I think that some of the bigger companies are doing that for themselves | 19:39 |
| KotCzarny | you would have to start selling 12V generators | 19:39 |
| KotCzarny | :) | 19:39 |
| sixwheeledbeast | I build my own "high quality" cartridges for UPS I general find the cartridges overpriced for what they are. | 19:39 |
| timeless | so, is there something i should do to try to "Vet" my vendor? | 19:40 |
| bencoh | KotCzarny: we're already using 12 batteries ... | 19:40 |
| bencoh | 12V* | 19:40 |
| bencoh | sixwheeledbeast: what do you make those of? | 19:40 |
| KotCzarny | yeah, but to save on conversions, you would have to provide 12V generators too | 19:40 |
| sixwheeledbeast | DC power would require much greater cost due to increased copper size between components. | 19:41 |
| bencoh | sixwheeledbeast: even with top-of-the-rack UPSes? | 19:41 |
| KotCzarny | swb: but you would save in long term? | 19:41 |
| sixwheeledbeast | Not necessarily depends on the installation. | 19:42 |
| sixwheeledbeast | I build my UPS cartridges with Yuasa's | 19:42 |
| sixwheeledbeast | You can get the double sided adhesive to stick them together if you build them generally from most places. At a push duct tape does a decent job. | 19:46 |
| sixwheeledbeast | Also you have to think about redundancy when it comes to a full DC rack. | 19:49 |
| bencoh | dual-supply DC/DC doesn't sound impossible (think consumer electronics) but I wouldn't know about that power level | 19:51 |
| sixwheeledbeast | timeless: looking at the model you posted a quick search I could "self refurbish" the cartridge for around equivalent of $190CAN with Yuasa branded | 19:58 |
| timeless | sixwheeledbeast: so, roughly ~$200 is the actual value of what i'm paying for? | 19:59 |
| sixwheeledbeast | minus the labour and shipping of doing the job yes | 19:59 |
| * timeless wonders about disposal/recycling costs | 19:59 | |
| sixwheeledbeast | I also recycle my own batteries and get money back there. | 19:59 |
| sixwheeledbeast | They are full of lead | 20:00 |
| KotCzarny | basically same rules as car accu | 20:00 |
| sixwheeledbeast | I suppose they are giving you a cartridge casing too no idea how much that would be worth. | 20:01 |
| sixwheeledbeast | TBH the solid cartridge type like that are the easiest to "refurbish" they just plug together. No need to built a battery pack up and stick batteries together like the desktop ones. | 20:03 |
| sixwheeledbeast | Example, RBC7 pack $170US I build my own for $110, 10 minute job. | 20:07 |
| KotCzarny | 19:23 #maemo timeless > i'm not interested in fiddling | 20:09 |
| KotCzarny | ;) | 20:09 |
| timeless | I'm a software guy! | 20:09 |
| KotCzarny | there is a chance you dont need any soldering | 20:09 |
| * timeless is definitely not doing soldering | 20:09 | |
| timeless | that's 5-10 bridges too far | 20:09 |
| KotCzarny | just some connectors and physical placement | 20:10 |
| timeless | right now i'm trying to figure out what to do to make the ups management software happy | 20:10 |
| timeless | right now it | 20:10 |
| KotCzarny | unless those cartridges have some anti-fiddler measures similar to printer's cartridges | 20:10 |
| timeless | 's sending me emails every couple of minutes screaming | 20:10 |
| KotCzarny | checked the manual? | 20:10 |
| sixwheeledbeast | Yours is a RBC43 by the way. As I say there is no soldering you may need a screwdriver at the worst. 10 minutes. | 20:12 |
| sixwheeledbeast | The only caveat is working out what size Faston connections you have and then it will plug together. | 20:13 |
| timeless | sixwheeledbeast: so, basically things that look like this? https://www.batterysharks.com/APC-RBC43-p/apc-rbc43_ups12-5.5_x8.htm | 20:14 |
| sixwheeledbeast | timeless: yes there is 8 of those in a RBC43. As I say I buy Yuasa (good brand) tho. | 20:16 |
| KotCzarny | yuase were doing car accus for honda | 20:16 |
| KotCzarny | *yuasa | 20:16 |
| timeless | http://yuasabattery.ca/ | 20:16 |
| KotCzarny | the factory mounted ones | 20:16 |
| timeless | http://yuasabattery.ca/advanced-search/ -> 500 | 20:17 |
| timeless | (so reassuring) | 20:17 |
| KotCzarny | yeah, basic stuff as sizes, terminal positioning etc | 20:17 |
| sixwheeledbeast | They are market leader for batteries | 20:17 |
| sixwheeledbeast | As I say I can get model numbers for the Yuasa's but I would need to know what size faston connections. | 20:18 |
| sixwheeledbeast | If it's Type A 4.7mm (Faston 4.7) then you looking at 8x "RE5-12" | 20:21 |
| timeless | https://clinicopc.com/store/index.php/component/virtuemart/?keyword=rbc43&view=category&option=com_virtuemart&virtuemart_category_id=557&Itemid= | 20:21 |
| timeless | "Our Shop is currently down for maintenance. Please check back again soon." | 20:22 |
| timeless | (great, i think i broke my apc management software) | 20:23 |
| KotCzarny | at least it will shut up | 20:23 |
| KotCzarny | :) | 20:23 |
| timeless | (i guess that's one way ... yeah, that) | 20:23 |
| sixwheeledbeast | Also yuasabattery.ca is not a genuine GS Yuasa site BTW | 20:24 |
| timeless | of course not | 20:24 |
| * timeless sighs | 20:24 | |
| sixwheeledbeast | https://www.batterycanada.com/rbc43.asp Not Yuasa but you can see the difference in cost. | 20:27 |
| sixwheeledbeast | Seems North America brand Yuasa as GS. Would be these http://www.gsbattery.com/ind-products/PE/PE12V4_5.pdf | 20:31 |
| timeless | is this the kind of thing that i can safely understand by watching a single youtube video? | 20:48 |
| sixwheeledbeast | timeless: https://www.youtube.com/watch?v=8SC_SZU3VYs | 21:00 |
| timeless | thanks | 21:02 |
| * timeless is multi-tasking (poorly) | 21:02 | |
| timeless | adventure of the day: upgrading the apc card firmware | 21:09 |
| timeless | do people use ssh, https, or just good old telnet/ftp/http? | 21:09 |
| KotCzarny | screen is handy on flaky links | 21:10 |
| timeless | and in general, how do people deal w/ certificates for network appliances? -- the modern world uses short lived automatically issued certificates, which means that loading certificates would require some automatable method (since it's a periodic task) | 21:10 |
| sixwheeledbeast | My home ones have USB connection. | 21:11 |
| timeless | i think this card has a usb connection but the disclaimer we got for it was "that software is for windows only" | 21:12 |
| timeless | we have a AP9630 card... | 21:13 |
| sixwheeledbeast | Ditto I still use apcupsd via USB it seems to work with my power mgmt daemon fine | 21:14 |
| timeless | hmm, so after updating the firmware, it says "ups status: unavailable" "online" | 21:26 |
| timeless | and "lost communication to ups" | 21:27 |
