8.3 DIMMs
Caution –
For maximum performance, the DIMMs in this system have been
specifically designed for it. Do not use DIMMs from a different system to upgrade or
replace the DIMMs in this system. Verify with your Sun sales or service
representative that the DIMMs you order have been Sun-certified for this system.
A failed DIMM can be identified by the address displayed in a memory failure error
message, or in POST. To identify a failed DIMM, see
TABLE 4-2
on page 4-5.
To remove and replace a DIMM, proceed as follows.
Caution –
DIMMs consist of electronic components that are extremely sensitive to
static electricity. Ordinary amounts of static electricity from clothing or work
environment can destroy the DIMM.
8.3.1 Removing a DIMM
Caution –
Handle DIMMs only by the edges. Do not touch the DIMM components
or metal parts. Always wear an antistatic wrist strap when handling a DIMM.
1. Power off the system, remove the system cover, and attach an antistatic wrist strap
as described in Chapter 5 “Preparing for Component Removal and Replacement.”
Caution –
Use proper ESD grounding techniques when handling components. Wear
an antistatic wrist strap and use an ESD-protected mat. Store ESD-sensitive
components in antistatic bags before placing them on any surface.
Note –
Always remove and replace DIMMs in order, beginning with the DIMM
closest to the edge of the motherboard (
