Memory Board/Memory-Module Kits (Netfinity 7000 - 8651)

Memory Board/Memory-Module Kits

NOTE:

•  The server uses 6Ons, 168-pin, error correction  code (FCC), dual inline memory modules (DIMMs).
•  The memory board contains four banks (0-3),  arranged in 16 DIMM connectors and supports  4-way memory interleaving.
•  You can install a maximum of 4 GB of memory in  the server, with 256 MB memory modules in all  16 connectors (J2 through J17).
•  Each bank contains connectors for four memory  modules. The memory-module kit sizes available  for the server are 64 MB, 128 MB, and 256MB.
•  As a minimum, the server requires 1 full bank of memory.
•  To ensure proper server operation, you must  maintain 4, 8, 12, or 16 memory modules in the server.
•  All the DIMMs installed in a bank must be the  same size, but different banks can have different sized DIMMs.

•  The base memory is four 64 MB DIMMs. The DIMMs  are installed in bank 0, connectors J2-J5.
•  You want four 64 MB DIMMS, eight 128 MB DIMMs,  and four 256 MB DIMMs in the server.
   Leave the 64 MB DIMMS in bank 0, connectors J2-J5 and install  the 128 MB DIMMS in bank 1, connectors J6-J9 and  bank 2 connectors J10-J13 and the 256 MB DIMMs in  banks, connectors J14-J17.

1.  Use DIMMs that are compatible with Joint  Electron Device Engineering Council (JEDEC) standards.
2.  The server does not support memory expansion adapters.

1.  Memory module (DIMM)
2.  Retaining clip
3.  Memory-module connector

1.  Place the memory board,. component-side up, on a  flat, static-protective surface.
2.  Locate the memory-module connectors on the  memory board.
3.  Touch the static-protective package containing the memory-module kit to any unpainted metal surface on  the server. Then, remove the memory-module kit from the package.
4.  Install the kit:

     To avoid breaking the retaining clips or damaging  the memory-module connectors, handle the clips gently.

   1.  Start with the lowest-numbered connectors (bank 0).
   2.  Turn the memory module (DIMM) -1- so that the pins align correctly with the memory-board connector.
   3.  Insert the DIMM into the memory-module connector -3- by pressing on one end of the  DIMM and then on the other end of the DIMM. Be sure to press straight into the connector.
   4.  Repeat the preceding step to make sure the DIMM is seated correctly.
   5.  Make sure the retaining clips are in the closed position.
   6.  If a gap exists between the DIMM and the retaining clips -2-, the DIMM has not been  properly installed. In this case, open the retaining clips and remove the DIMM, then, reinsert the DIMM.
   7.  Repeat these steps for each memory module that you install.

      NOTE: To ensure proper server operation, you must  install memory modules in groups of four. All the memory modules installed in a bank  must be the same size, but difterent banks can have different sized memory modules installed.

5.  Reinstall the memory board and board-support panel.

     When you install the memory board in the server,  be sure that it is completely and correctly seated  in the system-board connector before you apply  power. (The latches on the boards will be  horizontal.) Incomplete insertion might cause  damage to the system board or the memory board.
