Installing a DIMM
Use this information to install a DIMM.
Read the safety information in "Safety" on page v and "Installation guidelines" on page 75.
If you are replacing a server component or installing an optional device in the server, you need to take
out the node out from the rack enclosure, turn off the server and peripheral devices, and disconnect all
external cables.
Attention: Static electricity that is released to internal server components when the server is powered on
might cause the server to halt, which might result in the loss of data. To avoid this potential problem,
always use an electrostatic-discharge wrist strap or other grounding system when you work inside the
server with the power on.
The following illustration shows the location of the DIMM connectors on the system board.
