So today I learned how to measure amps on a server. First to do so requires some prep work.

We start by striping the insulation off a power cable since a clamp meter is only designed to be clamped around either the positive or negative wire but not both at the same time.

This should be enough. Next let us power up our server and see how many amps 1 side of the twin 1u supermicro server pulls.

1.8 amps? How have I not tripped a breaker?! Oh wait, I have... Next let us power up side 2.
