Re: [CentOS] Back to apcupsd
speaking of UPS's... I -almost- ordered $300 worth of UPS replacement batteries today, but on a hunch, I swapped electronic modules with a twin UPS (the ERM is hotswappable on these 2U 3000VA units), and lo and behold, its the ERM thats faulty, not the battery pack. found a fleabay ERM for $250 (OEM wants $1000).I have 3 of them, all about 5 years old, with 3 2U expansion battery packs, for a total of 9 battery packs, $2000-3000 to replace all of them. Um, well The beginning of the year, we had a utility shutdown for repairs, so we shut all our servers down, and the UPSs as well. Brought them back up after the long weekend... and it took over a month for the red light to come back. Watch out that the one you swapped doesn't come back in a few weeks. mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Watch out that the one you swapped doesn't come back in a few weeks. when I put the suspect ERM module in the other UPS it faulted. when I put the 'good' ERM back in its own UPS it was good. when I reinstalled the suspect ERM in the original UPS, it faulted. btw, fwiw, these are HP R3000XR UPS's http://h18000.www1.hp.com/products/servers/proliantstorage/power-protection/rackups/r3000xr/index.html, They have been quite good for me, this one ERM failure at 5 years old has been their only problem. with the battery expansion bay, they have like 20 minutes at full load (but I only have like 30-40% load on them). high efficiency, they run cool. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The APC SmartUPS 3000 started connecting and disconnecting the USB connection. I brought down and up the service, no joy. Finally, after googling, I found a *completely* undocumented way to start apcupsd, that a few years ago someone was told to try, so as to log debugging info, to send to a developer: apcupsd -d1000 -T I've just skimmed the man page, and the online docs, and there is *no* mention of either parm. I found nothing in the logs. However, when I kill -HUPped it, and restarted the service, the USB stuff had stopped. Ok, one problem down. The change battery light's still on. I'll see if it still is in the morning. One thing I did note, while skimming the docs, and comparing my results from apcaccess, was that while the nominal voltage for the APC SmartUPS 3000 is 48V, the new batteries are showing 55.4V. Anyone have any idea if this could be why the replace battery light's on - it's more than 5V difference? mark The light might stay on until either the next battery test, or re-setting the stored battery change date. I never have been able to get the date changed from *nix. I usually used a windows laptop with APC software installed. It can probably be done, just never spent a long time trying. signature.asc Description: OpenPGP digital signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

After doing this, you should see 12.6-12.8V per 12v battery, or 50.4 to 51.2V for your stack of 4 * 12V. All these voltages assume 68-72F battery temperature.48V is nearly totally discharged ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
