Supported Memory Configurations The following HP SIMMs are supported: SIMM Type 16 MB SIMM 32 MB SIMM 64 MB SIMM 128 MB SIMM HP Part Number D4891A-69001 D4892A-69001 D4290A-69002 D4893A-69001 DIMMs The 4 GB memory board, which uses DIMMs (Dual In-Line Memory Modules), replaces the existing SIMMbased memory that is part of the original configuration of HP LX and LXe NetServers. The 4 GB memory board enables the installation of as few as 512 MB or as many as four GB. Please note the following installation guidelines: • You can only add memory in 512 MB increments (four 128 MB DIMMs). • Within the 512 MB increment guideline, you can install memory in quantities from 512 MB to 4 GB. • DIMM slots are numbered from J2 to J33. You place the first DIMM in Slot J2, and fill 4 slots until 512 MB has been added. A complete 4 GB installation requires that you fill all 32 slots. See Figure 1-2 for the complete 4 GB memory installation sequence. The following figure illustrates the installation sequence for 512 MB of DIMM memory. The slot numbers correspond to the exact order of DIMM installation.
