Note the STR3123 reg is only for the 19" ver IIRR. If you ever want to verify the regulator is bad you can lift the diode in the protection circuit and it will stop it shutting down so you can check the output from the regulator.

Good point Ordy, I've updated the topic to reflect it's the 19" chassis Thanks for adding the additional tip as well, that will come in handy next time.

Well larger chassis use the STR3130, other than that same rules apply
