P420 in the mail a month ago ... A cookie to whoever notices whats missing!

[N1h1l1ty]

So I got this P420 in the mail about a month ago. Plug er into my DL380E, get the SAS cables plumbed, fire er up ... drives spin once ... then nada. Server doesn't see the controller, spend forever troubleshooting, neither of my HP boxes recognize the controller, debug LEDs aren't any help. Then I bother to actually look at the controller.

I know what's missing, but do you?

RAM?

RAM?

Nope

I suppose I should add that when I say don't recognize the controller, I mean the controller gets power, the drives spin... but there's nothing to indicate it exists in ILO or bios.

That thing that looks like a tiny hole on the blck ic?

Warmer

This would be my guess... Although the card also appears to be missing the bracket, the plastic shield that goes under the BBU/RAM, and the BBU/RAM card and associated battery.

edit: Here's a pic of what's missing.

Bingo. Hole in one.

Reddit has suggested this is an L6 inductor. I have very little backgrounds in electronics, but if anyone has any protips on sourcing this, this might go from a funny story / 45 dollar paperweight to a working P420 - Markings read R68 1315

Google search has turned up... very little

Yeah, that's a toughie - there won't happen to be a little inductor inside the shipping material that sheared off, would there? The only thing I can really tell you is that the R68 figure is significant since it tells you the inductance (R) value of the component (68µH), and i am guessing that the 1315 "might" be the max milliamps accepted by the inductor (1.315 Amps?), although some manufacturers use the value to denote the size of a given component. The closest match I can find on Mouser is this, but run it by an Electrical engineer first (I am not an EE), and see if someone here with a working HP P420 can measure out the physical dimensions on that inductor and look for more markings that can help. This can either be a quick buy-solder-and-fix, or it could be an item to be returned on eBay.

I ended up getting a lsi card with a missing part like your card. I messaged the seller and they refunded me and said keep the part. I still have it in my bin of stuff, but without know what goes there or a way to buy it, the card is pretty useless.

a few years back, i contacted 3Ware (maybe before their acquisition by LSI?) and told them which card I had and which component was missing. they immediate wrote me back with the component spec and a list of suppliers and part numbers I could use to replace the missing part. that was so awesome.... i don't know that they would do that now being part of Avago/Broadcom/LSI/3ware/etc.
