Hi Folks; I just bought a Polycom SoundPoint 500 off of ebay after having spent way too much time trying to get updated sip images for our cisco phones. The phone I bought didn't have an AC power adapter; Could someone please tell me the volts & amps that the dc plug that comes with the phone puts out? Thanks! Mike

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.

Does anyone on the list have recommendations on 12VDC based hardware which runs a stock Centos 4 (or even 5)? -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - - - Jason Pyeron PD Inc. http://www.pdinc.us - - Principal Consultant 10 Wes...

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

I need a program that will just run everything at max so I can measure the max power used on some systems. My 'Kill a Watt' meter should show up early next week. SO run that CPU at max, using all memory, and keeping the harddrive spinning. I can jsut do pings on the lan card for it to stay awake. I have searched here and on the net and have come back with nothing.

...g / filling such shells with 3rd party batteries? I have never had to replace batteries in an Eaton anything. I hope the following is both correct and useful. I have replaced a fair number (probably around a hundred) batteries in other UPSes and devices (like a Fuji X-Ray machine that takes 16 12VDC at 22AH batteries). That's over 200VDC at a Significant current (the batteries claim 12V, but they are charged to over 13V). I like batteries from RaionGroup.com or batterywholesale.com. There are some other companies out there that I will never buy from again. I try to get high-rate batte...

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....

Greetings to all, I recently connected a Tripp Lite SMX500RT1U unit to a Synology NAS (basically a Marvell ARM equipped box running a custom 2.6.24 Linux). I tried using the tripplite_usb driver contained in nut 2.4.1 with not much luck. It does read the model ID and VA rating properly, but fails at everything else - mains voltage (this is a 230VAC EU model), battery config, unit status etc.

I am having a problem with and Asterisk installation where two ports connected to a TDM400 card will have a very loud noise when you try to dial. The server has an OpenVox D110P, a TDM04B and a Xorcom Astribank 8 fxs. It is running Zaptel 1.4.11 and Asterisk 1.4.18. The problem always happens with two ports (34 and 35) which are connected to two GSM gateways. They will work fine for a week

Hello, nut recently told me that the batteries need replacing in my Eaton 5PX2200RT (ups) and 5PXEBM48RT (external battery pack). According to my notes, it has been just over 4 years since I installed them. Looking at on-line sales, these seem to use batteries in a pre-packaged plastic shell. I don't recall if that's what's in my units or not. Do you have any experience with

This is off-topic and the only connection with CentOS is that the laptop will be running CentOS... I am looking for a travel router/firewall for a number of reasons: - Protect against outside attacks when outside the office/home not relying on whatever protection the laptop/tablet/phone offers. - Allow for fast transfer for data between devices without being limited by the bandwidth of the
