The Sun Server X3-2L supports a variety of DDR3 DIMM configurations that can include quad-rank (QR), dual-rank (DR), or single-rank (SR) DDR3 DIMMs.
Note - While the Sun Server X3-2L does support single-rank DIMMs, that is, single-rank DIMMs can be installed in the server, Oracle does not offer any single-ranks for purchase, either as factory-installed options or as separately orderable options.
Caution - These procedures require that you handle components that are sensitive to static discharge. This sensitivity can cause the component to fail. To avoid damage, ensure that you follow antistatic practices as described in Electrostatic Discharge Safety.
Caution - Ensure that all power is removed from the server before removing or installing DDR3 DIMMs, or damage to the DDR3 DIMMs might occur. You must disconnect all power cables from the system before performing these procedures.
