• 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 and ensure that you observe the installation rules
and sequence. See "DIMM installation rules" on page 77.
To install a DIMM, complete the following steps:
