gryphon Posted December 1, 2005 Share Posted December 1, 2005 could it be your computer has restarted due to low current on the UPS ? Most computers reboot or just shutdown when your UPS is low on power. Quote Link to comment Share on other sites More sharing options...
spicy Posted December 1, 2005 Author Share Posted December 1, 2005 haw is my ups low on power? the battarry is fully charged. what makes the ups low on power, olso i noticed today in another restart that the ups was beeping and giving worning green lights at the moment of the restart which the pc is not responsible and the cut came from the ups. is that another kind of by passing? can the ups miss somtimes and make mistakes? or there is somthing rong with my ups...thx Quote Link to comment Share on other sites More sharing options...
veK Posted December 2, 2005 Share Posted December 2, 2005 wtf is ups anyway? never heard of it... either because the german translation is completely different and we (I) only know a german abbreviation or maybe I know what is meant if you name the full name and not just the abbreviation. ups for me means united parcel service... the guys who suck cause they never manage to deliver on time at my place for some reason...

spicy Posted December 2, 2005 Author Share Posted December 2, 2005 lol. Q1. What is UPS?The full name of UPS is "Uninterruptible Power Supply". It will immediately supply computers pure power to maintain normal operation when power failure. Quote Link to comment Share on other sites More sharing options...
gryphon Posted December 2, 2005 Share Posted December 2, 2005 unhook your computer from the UPS and see if you still have those shutdowns.I only use APC UPS systems and they also write log entries for each reboot and such. You might want to check those. Quote Link to comment Share on other sites More sharing options...
spicy Posted December 2, 2005 Author Share Posted December 2, 2005 the logs are normal .. i get few ac faild ac recoverd alerts evry now and then.. no logs were made during the restarts only the alarm beeb that usaly happen when power cuts down . maybe its a momentary bypass as a resolt of ups beeing out of order or jamed like the manual said anyway i will try to uninstall the software and remove the comunication line even that i dont think the s/w has anything to do with or that it had restarted my pc .edited: well gryphon at this point i am sure the pc is not reponsible for the restart because if the pc power unit or os faild or shot down then why would the ups give unstable voltting alarm beebs. the problem started at the ups first thats why it gave the alerts . then went to the pc and made it restart.. i tryed to force restart my pc and shot it off and on and all this did nt make the ups normaly to give any worning alarms coz the ups dont import failuer info from the pc at the revers it send that kind of data . right?

gryphon Posted December 2, 2005 Share Posted December 2, 2005 how did / does your computer restart when it happend. Just shutting down and rebooting like a normal shutdown, or instantly, like a power loss and don't properly shutting down ?coz the ups dont import failuer info from the pc at the revers it send that kind of data . right?Depends on your UPS, some have bi-driectionall communication and a memory for the computer state.Is this your UPS btw. ?http://www.gepbolt.hu/ii/infosec-500xp-ups_big.jpg Quote Link to comment Share on other sites More sharing options...
spicy Posted December 2, 2005 Author Share Posted December 2, 2005 yes i know what you mean...well it shot down like a power loss.. just like if the power cut bypassed the ups and hit directly my system...i guess thats what they mean in the manual that the ups may go into bypass mode for a secound or tow due to momentary failuer. i mean the instant shot down cant be coming from my system because there no reason for the ups to give alarm if my system was having a power problems i even made tests by force restarting my pc from the restart boton and the ups had no comment what so ever about that matter.. all the data send from my pc to my ups is about sysem shot down after 2 min from power failuer and there is nothing about beeping or restarting my system._ yes my ups is the one in the photo for more info : http://www.infosec.fr/fr/index-en.html Quote Link to comment Share on other sites More sharing options...
spicy Posted December 2, 2005 Author Share Posted December 2, 2005 quote from the user manual: Bypass Mode: This situation occurs more for on-line UPSs and is usually due to a fault in the UPS. Power bypasses most of the filtering that is done by the UPS subjecting the PC or any other electrical equipment to raw AC powerUnder normal situation, On-line UPS will supply power from transformer and will transfer to bypass only when UPS is out of order, overload, or overheat.Under normal situation, Line Interactive UPS will supply power from bypass through transformer. At this moment, transformer becomes charger. When power failure, transformer will transfer battery power to AC outputisnt that what is hapenning?? some power surges are bypassing the ups and hitting my pc?

gryphon Posted December 2, 2005 Share Posted December 2, 2005 does sound like it. For some reason (heating, overload) your UPS doesn't filter the power anymore and at the same time you have a powerloss or it will stop suppying power to your computer which shutsdown / reboots at that time.you must really have bad electricity comming into your home . ..

spicy Posted December 3, 2005 Author Share Posted December 3, 2005 yes. i do have bad electricty..and it comes usaly like electrecity failuer storms. and its like watching a horor movies when ure room light would start flashing on and off . it uslay go like this all night untill the next morning when it gose to normal again.. and at the day when those 2 restarts happened i was having one of the electric stormy night. so surly there is a relation coz now with the power ok, every thing is normal again... what i understand from the ups manual is that the ups will not give 100% backup i mean for some reason it will have some moments of disorder and the battary wont back the pc up in time. and if the power is bad at that time some bugs will bypass the protection.... or its not a timming thing, but it can be limited ability to deal with the incoming . for ex if i had 20 surges per hour and few spiks and a coupple low voltage events, the ups will not be able to stop them all .lets say the accuracy of the ups is 98% for ex that means with so many bugs coming in, one or tow of them will actuly bypass the ups and or the ups may needs to make an cricticals shot down for a sec or tow thats why its beeping. i olso got 2 bypass messages but my pc didnt restart which means the power bypassed again but wasnt bad enough to coz restart Quote Link to comment Share on other sites More sharing options...
