I have SR2612URR Intel server.
During firmware upgrade Intel® Server Board S5520UR Firmware Update Package for IDA, OFU, WinPE & EFI ( Download Intel® Server Board S5520UR Firmware Update Package for IDA, OFU, WinPE & EFI), at FRU/SDR update step I am asked for chassis number, my server chassis is not listed, the most close variant is SR2612UR. Can I chose SR2612UR for SR2612URR server?
Firmware is proposed under SR2612URR server downloads: Intel® Server System SR2612URR Specifications
The server system is end of interactive support (EOIS) but since your question is simple, yes you can choose the SR2612UR for SR2612URR server.
