search for: capacitor

Just for grins, pull off the cover and look at the electrolytic capacitors on the motherboard. Look for ones with the tops pushed up instead of being flat. This can cause all sorts of odd behavior. Often the machine with a blown capacitor will continue to run till it is powered off. Mostly I see this on Dell machines but have seen it on other machines as well. The...

...the card in FXS mode - for analog extensions. I did notice that one of my phones did not ring and I wondered why. I later read in Paul Mahler's book VoIP Telephony with Asterisk that in his section on the TDM400 on page 127 he says "In the UK, you may need an adapter that provides a ring capacitor, or the phone may not ring." Can anyone confirm this. Also what is one of those and where would I find a good supplier? I am in the trade so wholesale would be OK.

...various timing issues as well. In addition, Asterisk would sometimes take almost a minute to fully load and register its SIP and IAX trunks. Puzzled, I recompiled several times. No result. I checked my hardware. Didn't find anything. However, I did overlook one thing: * The motherboard's capacitor! Yep, you guessed it! It was bad. Now, I do not have any problems (I didn't bother replacing the motherboard, ended up using a spare PC). -------------- next part -------------- An HTML attachment was scrubbed...

Hi -- I'm running a server which is usually stable, but every once in a while it hangs. The server is used as a file store using NFS and to run VMware machines. I don't see anything in /var/log/messages or elsewhere to indicate any problem or offer any clue why the system was hung. Any suggestions where I might look for a clue? -- Michael Eager eager at eagercon.com 1960 Park Blvd.,

I'm having a problem that I hope those with greater experience might have some ideas on. I live up in the mountains where the power is ill-conditioned. Transients which would cause a computer to reboot occur on a daily basis. Power failures are frequent and can last anywhere from five minutes to five days. I have all my computers on UPSs so the first two problems are solved. I have a

And all of that just to work around the RAID write hole. Although batteries have disappeared in favour of NV storage + capacitors, meaning you don't have to replace anything on those models. jh

Hi Asterisk Community, I have a development with a TDM11B in it. I am trying to connect this to a exchange line as well as a UK telephone and are looking for some pinout information for the FXS port. Is it the centre 2 pins that at the tip and ring. I have been digging around the Digium site but cannot seem to pick up this info. Any help appreciated. Thanks -- Gary

I'm trying to optimize some database app running on a CentOS server and wanted to confirm some things about the disk/file caching mechanism. >From what I've read, Linux has a Virtual Filesystem layer that sits between the physical file system and everything else. So no matter what FS is used, applications are still addressing the VFS. Due to this, disk caching is done on an inode/block

...or made from chinesium, that is ) is a fair assumption. Practice teaches us that not all fair assumptions are also true :) Now, in the event that the UPS will refuse to come up even with the old batteries, I suggest a careful inspection of the electronic board, of the cables and especially of capacitors and places where the cables are soldered. Capacitors DO age with time and a bad connection ( maybe a cable just got loose ) may prevent proper functioning. wolfy
