PERC H200 (E2K-UCS-71): need resistor value for R83 (knocked off by fan blade)

General Discussion

Hi everyone,

While working inside my server, a fan blade struck my PERC H200
(board silkscreen: E2K-UCS-71(B), original from a PowerEdge T110 II)
and knocked resistor R83 clean off the board. The component is lost,
so I can’t read its marking.

R83 sits on the solder side, in a cluster near R86, R141 (a “000”
jumper), a SOT-23 transistor, and caps C112/C199. Photo attached.

If anyone has an H200 (or crossflashed 9211-8i equivalent with the
same E2K-UCS-71 board) on hand, could you read the printed marking
on R83, or measure it in-circuit? For reference, my in-circuit
measurements of neighbors:

  • R86: 4.37k
  • R11: 10.7R
  • R57: 101R
  • R224: 470R
  • R141: 000 (jumper)

My working theory is R83 mirrors R86 (~4.7k nominal), but I’d love
to confirm before soldering anything.

Thanks a lot — this card has served me well and I’d hate to retire
it over a single resistor.

Unfortunately, you didn’t get the screenshot included, so I took the liberty of trying to find fill-ins, at least of what I think is the right board, and the right resistor:

The pictures are curtesy of an Ebay listing, not my own. So I have no access to the board myself. Maybe someone can use them to help you out.

As asked, a few photos would be jelpful.

Does the board run without the resistor? I’m not asking you to plug it in and try it but if you alreadt tried it…

Are you comfortable soldering SMT parts?

Thanks maan, it’s on a eletronic technical right now, that’s why i don’t got a photo, but he cant’s find the value

i’ve tried the day that happen, it don’t post the sas bios and don’t show the disk’s on the system, but it don’t panic short circuit protection, just don’t work
