However, we have not found them to be 100% reliable. We use them with a mix of equipment from different vendors. While the units work fine when tested, in production they sometimes do not switch fast/early enough and we have experienced several equipment reboots due to this. We have tightened the thresholds in the CyberPower control software so that the UPS will kick in more frequently, but the adjustments are pretty limited. Because of this, we have moved the units to non-critical equipment or equipment that is protected by a redundant power source through an APC UPS. We've since stopped buying the units for server use, but may consider them for desktop use. --Blake ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
