Lukasz, For SE7520JR2, it has a mini-BMC on the baseboard which uses SSIF over I2C. However, when the IMM is connected, the mini-BMC is disabled, and all IPMI server management goes via KCS to the BMC on the IMM for added functionality. So there are two options: 1) Use the basic mBMC on-board for IPMI via SMBus/SSIF (i2c), or 2) Use the advanced IMM for IPMI via KCS But you can't do both.
