Installing a DIMM

When you install a DIMM in the workstation, keep the following guidelines in mind:
Memory modules must be installed and removed in pairs, observing sequential
■
slot positions.
Populate DIMM sockets 1 and 2 first, followed by sockets 3 and 4.
■
Note – An exception to this guideline is when a DIMM module fails and becomes
replaced with a unit shipped from Sun Microsystems. In that case, the DIMM
modules may be replaced individually.
To install a DIMM:
1. Turn off the power button on the back panel and all of the peripherals connected
to the workstation.
2. Remove the left-side access panel.
3. Gently lay the system on its right side on a stable, nonslip surface.
4. Identify the DIMM slots.
5. Align the DIMM with the proper slot.
