Remove a DIMM

DIMMs are cold-service components that can be replaced by customers. For the location of the DIMMs, see Processor Module Components.

1. Consider your first steps.
   • Familiarize yourself with DIMM population rules.

     See Understanding DIMM Configurations

   • Prepare the system for service.

     See Preparing for Service.

   • Remove the processor module. Place the processor module on an ESD-protect work surface.

     See Remove a Processor Module or Processor Filler Module.

2. Remove the cover from the processor module.

   Press the green button near the front edge of the cover and slide the cover back and up off the main module.

   
   
3. Locate the DIMMs that need to be replaced.
