Watch out for design crashes...

People design network cables and add nice features, like protective boots to help easily unplug them. Other people design servers and add necessary features, like reset buttons. But if all those people aren't paying attention to each others' efforts, design crashes can happen - like with this Cisco router, where plugging in a cable with a protective boot presses the reset button on the server. Woops. Design carefully, people!
