Is AC Power Your Problem?

When you're fighting a problem with equipment do you assume the AC power is OK?

Do you assume the AC ground is there and OK?

Well, the third world engineers designing this stuff also assume your AC power and ground is OK.

That's a lot of assumptions that can lead to chasing your tail for a long time. My hand is raised because I've been there and done that!

The various problems that can occur with AC power aren't obvious:

If your problem isn't intermittent, you're lucky. Just check the power outlet and get out your meter and take some readings.

Use a Battery Backup to run the equipment disconnected from the AC power to see if that's causing your problem.

If it is intermittent you'll have to do all that plus connect a laptop to the Battery Backup, running the Battery Backup utility software to see if something is happening to the power intermittently. Maybe at night? Maybe when certain equipment is fired up in the building or even by a next door neighbor using power?
