Servicing DIMMs
Up to 32 DIMMs can be installed in each processor module, for a total of 64 DIMMs in the
server.
DIMMs are cold-service components that can be replaced by customers. For the location of the
DIMMs, see “Processor Module Components” on page 18 .
Caution - This procedure requires that you handle components that are sensitive to electrostatic
discharge. This discharge can cause failure of server components.
