D. Processor Congurations
Single CPU Configuration
The PowerEdge R710 is designed such that a single processor placed in the CPU1 socket will function
normally, however PowerEdge R710 systems require a CPU blank in the CPU2 socket for thermal reasons.
The system will be held in reset if a single processor is placed in the CPU2 socket.
