I also have the R710  and these part numbers for the controller card and accessories. T954J for PERC 6/i controller card NU209 is for the battery JC881 is for the battery assembly cable You'll also need the cable for the hdd, which depends on if you have a 2.5 or 3.5 hdd slots.
Hi, I bought an R710 on Craigslist, but it came without a RAID card. I looked up the service tag and originally it had an H700. This is too expensive for me, so I thought I'd put a perc 6 in it. Does anyone know what part numbers I need? Thanks in advance.
