Troubleshooting Rule #1: Is it plugged in?
The first in my series of troubleshooting rules:
A surprising number of day-to-day problems are solved when you realize that the thing just isn’t plugged in. Oops.
The obvious sense of “plugged in” is “plugged into the mains supply” - the AC wall outlet.
But there are many other useful senses to look for:
Electronics: Are other cables (not power) plugged in between two things? Are the cables themselves working? Network cables, speaker cables, video cables, printer cables…
Software: Are components finding each other correctly? Mail clients pointing to the right mail server, DLLs found and loaded, CGI URLs correct, variable names spelled right…
People: Are people communicating - “plugged in” to the project, both logistically (e-mail address or phone number correct) and mentally (same expectations on both ends)? No news is not good news…
What must connect?
