Find that sweet 24 port switch mounted in your network closet, or RJ45 wall plate if you've gone full-geek and wired the house with CAT6. Repeat the phrase "this is my network and I'm totally authorized to pentest it" - then flip the evil red switch far forward, closest to the Ethernet jack, to put it in attack mode. It'll start booting and blinking - and at any time it's ready to be plugged into your network. Right outa the box it'll perform a simple nmap scan - and when the fun is done, the light will go green (and the trap will be clean). It's then safe to unplug.
