Install a DIMM
Use this information to install a DIMM.
Attention:
• Disconnect all power cords for this task.
• DIMMs are sensitive to static discharge and require special handling. In addition to the standard
guidelines for Handling static-sensitive devices:
– Always wear an electrostatic-discharge strap when removing or installing DIMMs. Electrostatic-
discharge gloves can also be used.
– Never hold two or more DIMMs together so that they touch. Do not stack DIMMs directly on top of
each other during storage.
– Never touch the gold DIMM connector contacts or allow these contacts to touch the outside of the
DIMM connector housing.
– Handle DIMMs with care: never bend, twist, or drop a DIMM.
Before installing a DIMM:
1. Touch the static-protective package that contains the new DIMM to any unpainted surface on the
outside of the server. Then, take the new DIMM out of the package and place it on a static-protective
surface.
2. Locate the required DIMM slot on the system board. See “DIMM installation rules” on page 58. Ensure
that you observe the installation rules and sequence.
To install a DIMM, complete the following steps:
