URL removed so bots leave it alone

It's now a hybrid. My big black tower which holds 2 motherboards, and used to be all Windows is now in mixed company..... Pay particular attention to the RAM quantity! I got 9x 512mb sticks of Micron ECC PC2100 for $80.00 USD (which is DIRT-ASS cheap!!), so both server boards now have 3gb of RAM in them. I've got some stuff for badcaps.net in development on this server, so even though you may not realize it, it is relavent to this site

Ahh ok, but almost

Not made a URL because I don't want googlebot to index it... And this URL will prolly bring you to techspot.com in a few days because I will for safety reasons remove it...

Awesome!

Re: Mixed breed

It's the software that does it, not the hardware

Any AMD or Intel server grade machine is 100% stable...

I've got an old AST 133Mhz machine running Win2K Server with as of now 400 days of uptime...

Re: Mixed breed

Wish me luck, the clock is gonna tick back to zero now, I'm just 2 hours and 20 minutes shy off the magic 497 days...

Re: Mixed breed

Damnit, there went my 68 day uptime................... Thunderstorm blew through, knocked out the power, and was out longer than my UPS batteries could run it........ So I start over........AGAIN....

shit!

[Per Hansson]

Re: Mixed breed

Well, since my uptime counter has now reset it is kinda hard to proove the system has been up for 502 days... Currently showing: 5 days 12 hours 25 minutes...

My poor old AST hardlocked too, I was hoping to reach 497 days with it but at 484 it gave up

i am sure you can do this.
most apc units do well even with bigger batts.
i have a 2000 with 4 8d agm on it.
even with the 22nf in the pic iots good for several hours if you kill monitors and such on the server.

I'm gonna need a few of those to make it thru another huricane season.
I hate the sound and smell of the dam generator.

Re: Mixed breed

Just be careful, some UPS units charging modules are not too kind about hooking up to many batteries, it can become overloaded by having to work longer than it was designed for...

Best to use a UPS that supports adding external batteries...

Re: Mixed breed

Per, let me get my ugly mug in here.

I've only read about ppl doing this and charging would not be an issue with heat build up,imho. When a stock battery starts failing, it would be taking a charge constantly because it could not gain full voltage to resist the charging voltage. I would guess charging current at no more than 1.5A and probably less, even as low as 0.5A.

I see the problem of heat gain during prolonged battery run time. Adding heat sinks and a fan to a UPS that doesn't have these inplace would keep the thermal switch from shutting the unit down.

I do realize the high end APC units do have fans.

Re: Mixed breed

Yea Galvanized, just as you said...

My APC Smart-UPS 1000 does not have a fan, but it's identical twin, the 1500, with bigger batteries, does have a fan that comes on whenever the batteries are charging... (the 1000 and 1500 are identical, the 1000 is just missing a fan and has some empty space where the larger batteries of the 1500 model would be...

[Galvanized]

Re: Mixed breed

I'm not trying to make this like the HDD thread but one would think the fan would come on during battery run not charging because of transformer heat at that time.
Batteries offer a huge sink for the little heat gain during charge. If the batteries are old and shorted internally, that last statement goes in the bin.

Re: Mixed breed

om my apc rs1000 the fan comes on when it switches to battery power only.

Re: Mixed breed

Galvanized; haha, yea, that was a "blond moment" I meant when the batteries are discharging of course...

Re: Mixed breed

many of the low end 12v -24v ups use lm317t variable reg which has overtemp protection.they will continue to pump 1.5a into a battery with one or more shorted cells till the good ones hit thermal runaway.
thats what happens when you find melted,bloated,bulging batts in a ups.
its not hard to add a fan.i do that to the best power patriot 850's i have.
about the biggest 12v ups you will find.i put in a 24v fan so no noise.
bore a hole in the front for a lighter socket and breaker too.
a 5mm hole for a white led as a nightlight finishes the job.the one on my bench has panel mount powerpoles too.freaks folks out when i grab their ham rig they brought for repair and plug it into a ups!

Re: Mixed breed

Yea, I said I was gonna post a pic of a APC UPS I fixed, got it free from work "it had been looked at but no one found a fault with it"

Took it apart, one of the batteries had cracked open, it is called a "leakproof battery" yea roight, there was acid all over the bottom of the PSU...

Even better the UPS had been used to protect the PLC and PC for a laser machine, standing in a rack but with the door open for unknown reason to me (i.e. lazyness on the operators part I think)

Anyway, not so bad at first but right outside of that cabinet stood a container where the laser dust from cutting was poured into, very very fine dust that blows easily... Right next to it was also the AC cooler for the machine, you can guess the rest

The UPS PCB was full of this shit, mind you this is actually conductive (i.e. it is steel residue and other misc junk from the laser cutting) I had to take the whole UPS down in pieces, washed the PCB's in the sink with hot water and some solving agents, watched the shit just drip of it

Took it out and blowed it dry with compressed air, next took the new batteries I had bought at Elfa at 50% the cost of APC original batteries but 2x longer lifetime (10 years) (quite a deal eh?) and fired it up, works like a sharm... It is a APC Smart-UPS 1500...
