Preface Introduction The HP NetServer LXr 8000 is an Intel-CPU based network server that can use up to 8 GB of memory. This memory is situated on two boards that communicate with the rest of the NetServer via the midplane connector. Each memory board can hold up to 4 GB of memory, arranged in four - HP LH4r | HP Netserver LXr 8000 Memory Upgrade Guide - Page 8
documents describe the HP NetServer LXr 8000: • The HP NetServer LXr 8000 Installation Guide • HP NetServer LXr 8000 Technical Reference Card • HP NetServer Online Documentation CD-ROM Tools You Need To install this accessory kit, you need the following tools: • An anti-static service kit (3M™ 8501 - HP LH4r | HP Netserver LXr 8000 Memory Upgrade Guide - Page 9
. The DIMM is sensitive to humidity, so desiccant has been packed in the bag containing the DIMM. When the DIMM has been installed and the HP NetServer is running, it is no longer sensitive to humidity. Unpack the shipping box and verify that you received the contents listed below for the Memory - HP LH4r | HP Netserver LXr 8000 Memory Upgrade Guide - Page 10
Figure 1-1. EDO DIMM NOTE Be sure to keep the bag around the DIMM sealed until you are ready to install it. • HP NetServer Memory Upgrade Guide (this document) 4 - HP LH4r | HP Netserver LXr 8000 Memory Upgrade Guide - Page 11
reconfigure your system after installing memory. However, we recommend that you use it to ensure that you have the latest drivers and information. • HP NetServer Online Documentation CD-ROM.

Guidelines The HP NetServer accepts one or two memory boards. You remove and insert the boards through the front of the server. The boards sit horizontally in two side-by-side bays, and plug into connectors on the server's midplane board. Each memory board supports four-way interleaving - HP LH4r | HP Netserver LXr 8000 Memory Upgrade Guide - Page 14
NOTE Keep both memory boards in the HP NetServer during operation, even if the secondary board has no DIMMs. The empty board acts as a terminator for the memory board slot. Figure 2-1 shows the location - HP LH4r | HP Netserver LXr 8000 Memory Upgrade Guide - Page 15
A memory board has 16 DIMM sockets and accepts 64 MB or 256 MB buffered EDO DIMMs (50 ns). Each board has a maximum capacity of 4 GB when fully populated with 256 MB DIMMs. The minimum memory configuration is four 64 MB DIMMs on the main memory board (in slots J1, J2, J3, and J4). Figure 2-2 shows a - HP LH4r | HP Netserver LXr 8000 Memory Upgrade Guide - Page 16
The standard configuration of memory is 256 MB on the primary board, as four 64 MB DIMMs in slots J1 through J4 (shown in Figure 2-2 above). Add memory four DIMMs at a time. If you use both boards, both must have the same type and number of DIMMs in the same slots. For example, if you have filled - HP LH4r | HP Netserver LXr 8000 Memory Upgrade Guide - Page 17
Key: Bank A (Slots J1, J2, J3, J4) Bank B (Slots J5, J6, J7, J8) Bank C (Slots J9, J10, J11, J12) Bank D (Slots J13, J14, J15, J16) J1 J2 J5 J6 J9 J10 J13 J14 J3 J4 J7 J8 J11 J12 J15 J16 Figure 2-3. Memory Board Banks 11 - HP LH4r | HP Netserver LXr 8000 Memory Upgrade Guide - Page 18
Observe these guidelines when adding memory: • Add (or remove) DIMMs to the memory board in groups of four. Each group of four DIMMs must fill one bank on a memory board. A bank must be either fully populated or completely empty. See Figure 2-3. • When populating a memory board, fill Bank A first, - HP LH4r | HP Netserver LXr 8000 Memory Upgrade Guide - Page 19
example, if one memory board holds eight 256 MB DIMMs in Banks A and B and eight 64MB DIMMs in Banks C and D, the other board must match this configuration exactly if card-to-card interleaving is to take place.) NOTE There is no special order for interspersing banks of 64 MB and 256 MB DIMMs on - HP LH4r | HP Netserver LXr 8000 Memory Upgrade Guide - Page 20
