Install a DIMM
Use this information to install a DIMM.
Before you install a DIMM:
1. Read the following section(s) to ensure that you work safely.
• “Installation Guidelines” on page 30
Attention: Memory modules are sensitive to static discharge and require special handling. In addition to the
standard guidelines for “Handling static-sensitive devices” on page 32:
• Always wear an electrostatic-discharge strap when removing or installing memory modules. Electrostatic-
discharge gloves can also be used.
• Never hold two or more memory modules together so that they touch. Do not stack memory modules
directly on top of each other during storage.
