DIMMs
The 4 GB memory board, which uses DIMMs (Dual In-Line Memory Modules), replaces the existing SIMM-
based 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.
