    1 Preparing for Installation Verify Contents CAUTION Do not remove the DIMM from its bag until you are ready to install it. Make sure the bag remains sealed. 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.

    2 Installing Memory and Memory Boards Memory Configuration 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.

  • 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 of the memory boards. Primary Memory Board...

    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).

  • 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.

    Bank A (Slots J1, J2, J3, J4) Key: Bank B (Slots J5, J6, J7, J8) Bank C (Slots J9, J10, J11, J12) Bank D (Slots J13, J14, J15, J16) Figure 2-3. Memory Board Banks...

  • 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, then Bank B, then Bank C, and finally Bank D.

  • 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 memory boards.

    3. Refer to Figures 2-1, 2-2, 2-3, 2-4, 2-5, and 2-6. Locate the slot where you will install the DIMM, and spread the two DIMM retaining clips outward. See Figure 2-10. Figure 2-10. Installing a DIMM Module 4. Align the notches on the DIMM with the notches on the socket. 5.

  • Page 29: Removing Dimms From The Memory Board

    CAUTION Do not rock the DIMM into place, but apply firm and even pressure. If a gap exists between the retaining clips and the DIMM module, remove the module and repeat steps 5-6. 7. Repeat steps 3 through 6 to install the other three DIMMs, according to the rules listed in “Memory Configuration Guidelines,"...

    When removing banks of DIMMs from a system with two memory boards, make sure that both boards have identical DIMM configurations when you finish. (But if you are reducing the system to its minimum memory configuration, four DIMMs, put all four DIMMs on the primary (right) board and leave the other board empty.) See “Memory Configuration Guidelines”...

  • Page 31: Replacing The Memory Board

    CAUTION Close all retaining clips on the memory board before inserting it into your NetServer. This includes clips on empty slots as well as those on slots containing DIMMs. This facilitates insertion of the memory board. 9. Replace the memory board. See "Replacing the Memory Board." Replacing the Memory Board Once you have installed the DIMMs required for your desired configuration, do the following:...
