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 max outp...

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 tried dd-ing the ISO onto a USB stick, as suggested in <http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7>, but it didn't boot. Did anyone have better luck with this? In any case, I got it working by running livecd-iso-to-disk on a Fedora-20 laptop. I've found before that this is the best program around for the purpose. But I've 2 queries about this: 1. Why isn't this

My company supplies me with a very nice HP nc2400. Much faster, more memory, etc than my old HP nc4010. Problem is the drive is not swappable, and they encrypt the drive (the OS is XP). The nc2400 has a DVD/CDRW and 2 USB 2.0 ports so I was thinking..... Make a Live DVD with everything I need but map /etc /root /home and /var/log (and what else?) to a USB flash drive (16Gb are available

Hello! At first, i want to run the latest HandBrake (version 0.93) on a Mac with Mac OS 10.4 (Tiger). The problem is, that Handbrake is developed for Mac OS 10.5 (XCode SDK is not compatible to Mac OS 10.4 one). So i decided to try it with wine/darwine. Because wine is better supported on Linux and you can get easier newer version (apt-get), i decided to run HandBrakeCLI.exe on Debian Etch
