Hi Everyone,
I just started building a system using an HP StorageWorks P4500 G2 chassis that I inherited, and I ran into the front-panel pin-out problem. The previous diagram was encouraging, but I wanted more things to work, so I went to work with my multimeter.
Here is what I found:
Because these LEDs can output multiple colors, I found it helpful to read the "LED Indicators" section of the manual. The manual version I am using is this one. This gave me an idea of what features I should be looking for.
Caveats:
Of course, this is not an exhaustive scan of all pin combinations, nor do I understand anything about the circuitry inside the front panel. I still don't know what the yellow wire connecting to pin 12 does.
I suspect that they get the amber color for the System Health LED by turning on the green and red LEDs at the same time. I could be wrong. When I tried to light up this indicator, it was very faint compared to the others, and I had trouble making it out.
I am not %100 sure this is the same pin-out as the DL180 G6 front panel header, but so far these machines seem incredibly similar, so I think it will be alright.
Now if only I had pin-outs for the HDD backplane and power backplane...
I hope this helps a bunch of people encountering this thing.
