• FrankenUPS Hack Turns a Server UPS into a Whole House UPS

  - by Jason Fitzpatrick

  This well documented build guide showcases the process of turning a rack-mounted UPS battery device intended for a server bank, into a super-charged whole-house UPS system with a massive 14 hours of backup juice. It’s a very ambitious build and, due to the work required in the main circuit breaker of your home, we highly recommend only those experienced with electrical work undertake the project. That said, it’s a really clever bit of recycling that yielded an impressive half-day worth of backup power. Hit up the link below for the detailed build log.

• APC UPS replace battery light and apcupsd reporting "replace battery"

  - by mgjk

  We have an APC Smart UPS 1500. The "Replace Battery" light is on, and apcupsd reports: Emergency! Batteries have failed on UPS xxxx. Change them NOW However, from this article, http://sturgeon.apcc.com/kbasewb2.nsf/for+external/f39c4312fcaf7b948525679a005ebb78?OpenDocument it seems that it's not so clear that the UPS battery needs to be replaced. Stranger, according to the information on the UPS, an 11 minute runtime at 42.9% load running at 27.7V isn't so bad. Any thoughts about what to try next? We're a non-profit, money is an object. It would be a shame to replace a battery with a year or so left in it. # apcaccess status APC : 001,041,1017 DATE : Thu Mar 29 13:01:41 EDT 2012 HOSTNAME : oreilly2 VERSION : 3.14.6 (16 May 2009) debian UPSNAME : xxxx CABLE : Custom Cable Smart MODEL : Smart-UPS 1500 UPSMODE : Stand Alone STARTTIME: Thu Mar 29 12:57:30 EDT 2012 STATUS : ONLINE LINEV : 112.3 Volts LOADPCT : 42.9 Percent Load Capacity BCHARGE : 100.0 Percent TIMELEFT : 11.0 Minutes MBATTCHG : 5 Percent MINTIMEL : 3 Minutes MAXTIME : 0 Seconds OUTPUTV : 112.3 Volts SENSE : High DWAKE : -01 Seconds DSHUTD : 090 Seconds LOTRANS : 106.0 Volts HITRANS : 127.0 Volts RETPCT : 000.0 Percent ITEMP : 23.8 C Internal ALARMDEL : Always BATTV : 27.7 Volts LINEFREQ : 60.0 Hz LASTXFER : No transfers since turnon NUMXFERS : 0 TONBATT : 0 seconds CUMONBATT: 0 seconds XOFFBATT : N/A SELFTEST : NO STATFLAG : 0x07000008 Status Flag SERIALNO : AS0603298896 BATTDATE : 2006-01-14 NOMOUTV : 120 Volts NOMBATTV : 24.0 Volts FIRMWARE : 601.3.D USB FW:1.5 APCMODEL : Smart-UPS 1500 END APC : Thu Mar 29 13:02:12 EDT 2012 Error when running upstest You are using a SMART cable type, so I'm entering SMART test mode mode.type = USB_UPS Setting up the port ...

• Setting up UPS monitoring

  - by Andrew Heath

  I have acquired a second hand Uninterrupted Power Supply (UPS) that I have refurbished (new battery) and hope to use with my Ubuntu 12.10 system. It's a SOLA 330 with serial out. I have installed NUT Metapackage and NUT Monitor from Software Centre, but am not sure how to go about setting it all up. A Google search brings up several ways of configuring Network UPS Tools (NUT) or HAL-Drivers, however, HAL-Drivers appears to be obsolete and many commands and config files mentioned to edit do not exist in 12.10 or the current version of NUT (most articles are a few years old). One tutorial seemed to work except the Error: no UPS definitions found in ups.conf even though ups.conf has values in it as laid out in the tutorial. How do I go about setting my system to monitor the UPS for a shut down signal? Also, is there a command to determine the UPS is communicating through the serial connection and on what port (to help with setup and configuring, eg. /dev/ttyS0 is mentioned in one of the tutorials I read).

• how to print labels from UPS printer on UPS website

  - by paynes_bay

  I have several computers, in my office, that have UPS printers attached to them. On most of these computers if you go to ups.com, login, and print a shipping label out, it prints out just fine. The website somehow selects the appropriate printer and prints to it. It doesn't present a prompt, asking you to select the printer, the number of pages, etc - it just prints it. Only problem: there's one computer on which it's not doing this and I don't know why. I can see the printer in Printers and Faxes and can print out test pages from the Properties tab, so the printer clearly works - it just isn't printing out from UPS's website. Any ideas?

• How to detect APC UPS battery usage and run a script when on battery

  - by Andy Arismendi

  I have a couple APC UPS - Smart-UPS RT 6000 RM XL Smart-UPS RT 5000 RM XL Unfortunately the power in my office likes to go out (out of my control) and hence the equipment powered by these UPS shuts down. They power a VMware infrastructure environment (VMware Lab Manager) and what I'd like to do is detect when one is on battery (say has been for x amount of time or has x percentage left) and run a script on this event. What software do I need to detect a on-battery event and have it run a script? Thanks!

• nut (UPS) and SSL certificates

  - by Mausy5043

  Today I installed nut on my Ubuntu server (14.03). $ uname -a Linux boson 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux The UPS is connected to another server (called neutron), so I use nut-client to keep tabs on the UPS state. When I do sudo upsc [email protected] I get: Init SSL without certificate database battery.charge: 15 battery.charge.low: 10 battery.charge.warning: 50 battery.date: not set battery.mfr.date: 2012/11/27 : The first line of the output concerns me. I've not seen this on other installations of nut on Debian-based servers. What can I do to get rid of that line? EDIT: This "Init SSL without certificate database" is extra annoying because it is not part of the output of upsc and therefore I cannot grep it out.

• UPS with a HP Proliant server

  - by Groo

  We placed a EATON Ellipse Max 1500 (900W) as the UPS for our HP Proliant ML350 G6. Upon first power failure (actually we only moved the UPS' input plug to a different socket), server immediatelly turned off, and the Health LED turned red and started blinking. UPS was in operation for about a week before that, with battery fully charged to 100%. Since our server's hot-plug supply is 460W, we are pretty sure we haven't overloaded it, the server was completely idle at that time (no web or win apps running except Windows Server core services). Then we tried to do the same with a different, no-name older PC (Core 2 Duo, 2Gb RAM) with a generic power supply (not sure what the power is) and it continued working when we pulled the plug out. UPS load was less than 15% (measured in the provided Eaton utility). We measured the UPS' output voltage using a smart oscilloscope and the THD of the UPS output waveform turned out to be 40%. Did you have similar experiences? Could this be a faulty UPS? Or a faulty power supply? Or some HP sensors configured to trigger too strictly? I wouldn't like replacing this UPS with the same brand, to get same results. [Edit] I also tried to do this while the server is turned off. While the UPS is working on battery, server will not start - as soon as I press the power button, Health LED starts blinking red.

• APC Smart UPS network shutdown issue

  - by Rob Clarke

  Here is a bit about our setup: We have 2x Smart-UPS RT 6000 XL units with network management cards We are running Powerchute from a network server Powerchute is connected to the management cards of both UPSs UPSs are set to do a graceful shutdown via Powerchute when the battery duration is under 20 minutes We also have a command file that runs with Powerchute Although our setup is redundant we do not have an equal load on each server due to APC switches for single power devices The problem is that as we do not have an equal load on each server the batteries drain at different rates. This means that the UPSs both get to the specified low battery duration at completely different times. The problem here is that UPS 1 may have run down to 5 minutes and is in desperate need of initiating a Powerchute shutdown - UPS 2 still has 25 minutes of runtime so no shutdown is initiated. Consequently UPS 1 goes down and takes all the servers with and then shuts down UPS 2 as well! What we need to happen are 1 of either 2 things: Powerchute initiates the shutdown as soon as either UPS reaches the 20 minutes low battery duration setting - and doesnt wait for both The UPS with the heavier load expends its entire battery but does not shutdown both UPSs and lets the load be switched across to the UPS that still has runtime remaining. That way when the UPS that still has runtime reaches its low battery duration it can proceed with the graceful shutdown via Powerchute. Hope that makes sense, any help is greatly appreciated!

• Windows server 2008 UPS support

  - by Rory McCune

  I'm looking to set-up a UPS on a Windows Small Business Berver 2k8 and I've noticed that there are some large price differences for similar capacity in-line UPSs. The most important point for me in UPS selection is that the server should have the ability to shut itself down before the UPS power runs out, so that if the server is unattended during the outage, it should minimize the risk of data loss. From some reading it appears that Windows Server 2008 should has the ability to natively recognise a UPS, which can then be managed through the battery settings on the server or via WMI. What I'm wondering if anyone know is, Is Windows 2008 servers UPS support specific to certain brands of UPS (eg, APC) or is it likely to work with any UPS which has a USB port, which I can connect to the server?

• Radiation from a UPS

  - by Erel Segal

  In our office, there are frequent eletric shortages that harm my desktop computer, so I wanted to install a UPS. However, my office-mates pointed me to papers talking about hazardous radiation from the UPS. The UPS manufacturers themselves recommend to put the UPS several meters away from humans, which is not possible because our office is small (the power is about 0.5 meters from us). As an alternative to UPS, my office-mates recommended that I switch to a laptop, which has a battery so it's immune to shortages. I have several questions: Is it true that the radiation from a laptop battery is lower than the radiation from a UPS? They do just the same thing - supply power using a battery! If the answer to 1 is yes - is there an alternative way to attach a battery, similar to a laptop battery, to a desktop computer? If the answer to 1 is no - how can I prove this to my office-mates, so that they let me use UPS?

• Can an UPS be too powerful?

  - by Andy

  Our old network admin bought the top range UPS a few months ago but never came around to setting it up and is no longer with the company. Now the old UPS broke down and needs to be replaced, but an external company that did an audit said that that UPS won't work. Now we are no hardware specialists, but the difference in specs is a higher output from 5A to 8.8A meaning a higher output. But isn't the UPS supposed to give the server the required output anyway? This 'independent' audit does sell its own hardware including UPSes so I'm not sure how much bias they have. Is there a reason why we can't replace the old broken UPS with the new more powerful one? Is there a way we can check to see if the UPS works with our server? ok, i wrote down the numbers again, the Volts and Amps are what are on the back (where you connect up the plugs which seem diffrent from on the front label.) old one APC SmartUPS 1500 220-240V -- 6.8A new one Dell UPS 1920W 250V -- 10A

• UPS and power strip interactions?

  - by chaos

  Sometimes I hear that you shouldn't plug (UPS brand X / any UPS) into (power strip brand X / any power strip) because of some interaction leading to poorly conditioned power, reduced battery life, massive explosions spattering the room with battery acid, and so on. Sometimes I hear that it's the power strip that you shouldn't plug into the UPS. What I haven't gotten is a clear idea of how reliable these recommendations are or how generally/specifically they apply. Can anyone speak precisely and non-urban-legendfully on these UPS and power strip interactions, if there are in fact ones worth thinking about?

• trouble connecting ups

  - by Jure1873

  I've got a riello UPS connected to my server through USB. The output from dmesg is: [1362998.520035] usb 2-2: new low speed USB device using uhci_hcd and address 7 [938715.763270] usb 2-2: configuration #1 chosen from 1 choice [1363008.726243] input: Ups Manufacturing RS232-USB converter as /class/input/input7 [1363008.749408] input: USB HID v1.00 Gamepad [Ups Manufacturing RS232-USB converter] on usb-0000:00:1d.0-2 Now the program for controlling the UPS is expecting me to input the device path (/dev/ttyUSB0), but it doesn't get created.

• MGE UPS Cut power - What happened?

  - by JT.WK

  I have 3 x MGE Pulsar M 3000 2700w UPS units within my server room which have run perfectly up until now. On Saturday morning I noticed that one of these UPS units was no longer outputting power, the lcd displayed a message saying "load not powered" and told me to press the power button to start output. Needless to say that the servers, switches and routers is was supporting were all turned off. I tried pressing and even holding the power button, but the unit refused to start back up again. Only power cycling the unit got it back up again. I have checked the logs on the UPS, although they were useless. Nothing out of the ordinary, and no email notifications had been sent. The output level sits on about 51% and all battery checks are OK. It is now three days on and the UPS is still up and running (although I am scheduling an outage to get it out of there ASAP). Does anyone have any idea what could have gone wrong here? Is there anything else that I can check that could help?

• Assistance in setting up new APC Smart-UPS RT on a new VMware enviroment

  - by user38085

  I'm new to the realm of setting up a APC Smart-UPS RT 8000VA UPS with a management network card (AP9618). The project calls for the upgrade of the firmware for the network card to the newest and greatest. It also calls for the Powerchute Business Software to be installed with notifications setup per email for temperature, shutdown, and battery low. I know I'll have to use the serial cable to flash the firmware and install the software on one server 2003 box. Also on that server I'll have to install the software and setup the GUI (IP address) interface. Whats confusing the most is the whole process, and steps to use without taking down the network, which would be very bad. In flashing the firmware does it take down the UPS? Do i have to run BOOTP commands to setup the network card? Also no agents will be used on any of the VWware OS's and no SNMP trap will be used.

• UPS for hard drive protection

  - by dimi

  I am in a place where electricity is not ideal (old house, no ground), sometimes it occasionally shuts down and supposedly there are some spikes. I consider using UPS with the goal to increase safety of my personal data. My first priority is the health of my internal and external USB hard drives which can be damaged due to possible power instability. I do not care that much about possible losses of not-saved work, instead I just want to let my system have a minimum time to turn off without any risk of physical damaging my hard drives. Would a cheap offline UPS suit my neads? Or do i need a better one with automatic voltage regulator (AVR)? How critical is AVR for the hard drives? The external ones require their own power supplies and will be plugged directly into UPS.

• One server, Two APC UPS on redundant power supplies : How to trigger shutdown ?

  - by Falken

  I have a server racked and its redundant power supplies plugged in two APC Smart-UPS 3000 XLM. Each UPS is connected to two different mains power sources. Two instances of apcupsd are running, each one connected to its own UPS. They can both detect when an UPS is on Battery, and each UPS can then trigger a shutdown on the server. Question is : How NOT to shutdown if ONLY ONE UPS runs out of battery ? Note : Smart-UPS 3000 XLM has a "Power Sync" Function that is able to connect to its peer and detect its status. But when I pulled the plug out of one of them, the Shutdown order was sent anyway. I'm thinking about modifying the shutdown scripts to check with "apcaccess" if the other ups is down. Any experience on this would be appreciated !

• UPS power requirements for server

  - by captainentropy

  Greetings! So, I just placed an order for a new server. The company recommended that I get a 3000W UPS. (!) As best as I could I calculated the following wattage consumption based on benchmarked data or datasheets provided by the manufacturers of each component: number watts **total watts** MoBo 1 240 240 CPUs (E5540) 2 80 160 RAID cards (3ware) 2 18 36 RAM (6x4GB) 6 3 18 DVD drive 1 7 7 floppy 1 2 2 RE4 drives 8 7 56 WD20 drives 8 6 48 Intel X25 SSD 2 0.15 0.3 total = 567 So that is for the PSU requirements only. The PSUs in the machine are a 720W for the master node and 800W each for two subsystems. That's a total of 2320W that can be delivered by these PSUs. But that is 4X the amount being consumed, at most, by the components. I didn't count case fans or the eSATA card (3W maybe?) or what the PSUs themselves require but assuming I double or triple my calculations I'm not even remotely close to the 3000W UPS I was suggested to get. They run at least $1100. I could get a 2000W for about $750 or a 1500W for $450 and still be well over my estimated power need. I don't think I need a whole lot of run time in the case of a power outage, maybe 20 minutes max, enough time to shutdown if the power doesn't come on within 5-10 minutes. Any thoughts? Am I off on my calculations? Did I overlook something major? If so what are your suggestions for a UPS? Thanks!

• APC ups es 700 randomly overload

  - by Matteo Mosca

  First of all, I live in Italy, Europe, so keep this in mind for Volt/Watt considerations. Standard voltage in Italian apartments is 220V. In my living room I have 2 APC ups, one being an ES-550 and the other an ES-700 They each have 4 slots for surge protection only, and 4 slots for surge protection + battery backup. Just to give all the information, they both got their battery replaced less than one month ago. The ES-550 works fine, without any problem. On the battery I have connected: Pc Monitor Sony Bravia 46'' 4th slot is empty The ES-700 has the following on battery: Xbox 360 Ps3 (standby when not used) Wii (standby when not used) Netgear 8 port switch (always on) Here's what happens: the ES-700, randomly, but mostly at night when I'm sleeping, goes like "overload", with the constant beep. If I try to shut it off keeping the power button pressed, nothing happens. The only thing that works is unplugging random stuff (sometimes unplugging 1 console works, other times I have to unplug all 4 devices). Every time this happens the problem is "real", meaning the 4 devices become unpowered, so it's not just an "alarm no working properly" problem. While I'm sleeping, of course, the power usage is what described on the list, 2 devices on standy, 1 off and 1 on. Today it happened again while I was playing with my Ps3. I unplugged it, problem went away. I plugged it again, and it kept working fine. I just can't figure out what's the problem. The only additional info I can provide is that this behaviour started after a big power outage last december 26 (a blackout that lasted almost all day) but the "surge protection" part of those UPS should be there for those problems, to leverage peaks when power goes away or gets restored. Another funny thing is, althought it might not be related, for a couple of days after that event the Wii was unable to power on, I thought its power transformer was broken, but then it suddenly started working again. I can be sure it's not the Wii overloading the UPS because the overload happens even if I leave the Wii unplugged. Any suggestion is really appreciated, and I can provide any additional info, if needed, that didn't come to mind right now. Thanks.

• Is UPS worthwhile for home equipment?

  - by Jon Skeet

  Over the years, I've had to throw away a quite a few bits of computing equipment (and the like): Several ADSL routers with odd symptoms (losing wireless connections, losing wired connections, DHCP failures, DNS symptoms etc) Two PVRs spontaneously rebooting and corrupting themselves (despite the best efforts of the community to diagnose and help) One external hard disk still claiming to function, but corrupting data One hard disk as part of a NAS raid array "going bad" (as far as the NAS was concerned) (This is in addition to various laptops and printers dying in ways unrelated to this question.) Obviously it'll be impossible to tell for sure from such a small amount of information, but might these be related to power issues? I don't currently have a UPS for any of this equipment. Everything on surge-protected gang sockets, but there's nothing to smooth a power cut. Is home UPS really viable and useful? I know there are some reasonably cheap UPSes on the market, but I don't know how useful they really are. I'm not interested in keeping my home network actually running during a power cut, but I'd like it to power down a bit more gracefully if the current situation is putting my hardware in jeopardy.

• UPS recommendations for three grey boxes?

  - by Margaret

  Hey all We have a series of grey-box style computers acting as servers at my workplace (rather than rack-mount). We were looking to get Uninterruptible Power Supplies for them. However, I'm not sure how many at what capacity are required. I'd assume it would be a good idea to hook the peripherals in as well - there's a 18.5" LCD monitor with a KVM, along with a couple of USB hard drives that require power. I currently have the most vital machine hooked up to a cheap (temporary) UPS, but it's probably close to worse than nothing. I'm looking for reasonable value for money, though I can probably negotiate with my boss on price range. I recognise that I may well need to buy two (or even three) UPSs to support the three machines. Any recommendations?
