For memory on-line sparing, one DIMM per channel is used as the memory spare. If a DIMM
begins to fail, the content of the failing DIMM is copied to the spare DIMM in that channel. When
all of the data is copied to the spare DIMM, the primary DIMM is removed from service and the
spare DIMM takes its place. When memory on-line sparing is used, the spare DIMMs must be
equal to or larger than the largest in-service DIMM in that channel.
For additional information, see the Intel® Server Board SE7520BD2 Technical Product
Specification.

For the Intel Entry Server Chassis SC5295-E BRP, a minimum 500W power supply is required.
