Does anybody happen to know the input power specs for the Polycom IP 500 and IP 600? We've mixed up our power supplies and we've got a whole box of them and can't figure out which go to the Polycoms. I would rather not kill the phones by trying random ones....

I've been playing around with a new system I'm going to install in another office. In setting up the Polycom's, I accidently used a new power supply from a new 601 (24VDC) with an 600. The 600 only require 12VDC. Now, I get nothing on the screen of the 600 when I plug in 12 VDC. (At the time, I didn't even realize the power supplies were supplying different voltages.) Guess I'll have to buy a new 601 to replace the 600.

...detection of incoming PSTN calls. * answers the call, but if the incoming caller hangs up, * does not release the line. I have determined the following information about my line: When On-Hook line voltage = 24.5VDC When Off-Hook line voltage = 8.27VDC When Ringing line voltage alternates between 24VDC (no ring) and 40+VDC (ringing) I also determined that when a caller hangs up, there is a couple of clicks on the line, then a dial tone. I am using Kewlstart signalling. I have tried BUSYDETECT and CALLPROGRESS, but to no avail. Does anyone have a solution for this? Can anyone tell me what type...

Hello people, I am having difficulties figuring out the POE power draw in watts from a Polycom IP601. I want to know how many IP601's can be powered from the Cisco Catalyst 3560G-48PS. The IP601 wallwart has: Input 120VAC 60hz 19W, Output 24VDC 500mA. I assume the output is appropriate value to figure out how many phones can be powered. The Cisco 3560 datasheet says "the 48-port PoE configurations can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between" ...370 Watts POE ma...

Leslie, This message is most appropriate for the NUT user list. I kept Rik Faith's and Nicholas Kain's copyright information because the tripplite_usb driver borrows heavily from the tripplite (serial) driver, but they are not responsible for the mess that I made in the USB driver.

I have a CentOS-5.6 remote server in a house in Italy, where there are occasional thunder-storms. There was one yesterday, when the electricity went off 3 times, for a second or so on each occasion. My server, an HP MicroServer, came back (re-booted) on 2 of the 3 occasions, but not on the third. I assume that the problem arises because the machine does not close down properly. (Although it is
