SO-DIMM Installation in a Non-Powered System
Note
■ The SO-DIMM onboard the ATCA-C110/1G can be installed only when the module is
removed from the carrier board.
■ It is recommended to use the SODIMM that is factory-shipped along with the
ATCA-C110/1G, since it has already been verified and validated.
If using SO-DIMM other than the standard supplied SO-DIMM, ensure that the following
requirements are met when power is turned off.
■ Is unbuffered
■ Is 2.5V, PC166 SDRAM module compliant to the JEDEC Specification
■ Has size of either 128 MB, 256 MB or 512 MB or 1 GB. (The MPC8540 will configure
memory maps automatically on boot)
■ Supports ECC
