Yes, that makes it a beep code. Beep codes don't have to be from a PC motherboard, its just a way for headless devices to tell you what is wrong. Whatever that sound is should be documented by the manufacturer.
Ben, These are the 'beeps' that the UPS makes when it transitions to battery mode. It's not an error, just a notice that the AC is not charging the battery, but the battery is powering whatever is connected to it. This lasts a couple or so seconds every now and then. This happens her when the lights and radio don't show interruption in their operations. Infrequently, the surge protector into which the WAP is plugged will trip off, otherwise there's no indication of a power glitch. Apparently the APC backups are more sensitive to voltage changes than are other electrical devices. Similar quirks occur here with my cell phone (a Treo 700p). It's sitting next to me on a rubber pad on top of a 2-drawer file cabinet. Every now and then it generates its 'lost signal' sound, followed a short time later, with its 'network found' signal. Why this happens with the unit sitting in one place is unexplained. Weather seems to not be a factor. It happened when I was on the cell phone with a Verizon tech and she could not explain why. Strange things, these computers. Rich _______________________________________________ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
