FIGURE 11-1 DIMM Location and Identification
Depending upon the configuration of your workstation, you can either add or
replace memory. In either case, the new DIMMs must meet the Sun workstation
requirements.
TABLE 11-1 lists the acceptable DIMM pair configurations.
When your workstation boots up, the OpenBoot PROM checks for compatible
memory modules. Refer to “OpenBoot PROM” on page 8-1 for additional
information.
If you are not removing an existing DIMM, proceed to “Installing DIMMs” on
page 11-8.
