Not nice... You're supposed to pull the fuse or breaker before working on fixed wiring. I wouldn't rely on a switch, some only break one half of the circuit, and if there's bad wiring, that mightn't be the live half. At least, when you're working on stand-alone gear, you can unplug the cord and take it with you. The second half is important, there's always someone who'll see you working on a set, and helpfully plug it back in for you. You also ensure that you unplug the device that you're working on, and not something next to it. -- [tim@bigblack ~]$ uname -ipr 2.6.22.9-91.fc7 i686 i386 Using FC 4, 5, 6 & 7, plus CentOS 5.
