Servicing CRUs That Require Server Power-Off 63
In addition to the service procedures included here, you can see animations that
show how to remove and install DIMMs.

The Sun Server X4-2 supports a variety of DDR3 DIMM configurations that can
include quad-rank (QR), dual-rank (DR), and single-rank (SR) DDR3 DIMMs.
Note – While single-rank DIMMs can be installed in the Sun Server X4-2, Oracle
does not offer any single-rank DIMMs for purchase, either as factory-installed
options or as separately orderable options.
Caution – These procedures require that you handle components that are sensitive
to electrostatic discharge. This sensitivity can cause the components to fail. To avoid
damage, ensure that you follow antistatic practices as described in “Take Antistatic
Measures” on page 42.
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.
The following sections provide information to assist you when replacing or
upgrading a DIMM:
