Re: Raidmax RX-600 ringing noise and 0ms PG
According to that datasheet, your PS224 PGO pin is an open drain. So that burnt resistor and diode may be a pull up? It should be to 5v though...
Maybe they use 12v to pull up PGO and that transistor you find connected to PG wire is a level shifter circuit. Why the heck they would do that though...?
Anyway, if the resistor burnt, something may be shorted on that PG line, or it was plugged into a faulty motherboard.
