Memory-Module Kits

Memory-Module Kits

Note: If installing a 256MB Registered memory module in the server, ensure the jumper is installed on pins 2 and 3 of Jumper Block J12 on the processor board.

Adding memory to the server is an easy way to make programs run faster. You can increase the amount of memory in the server by installing options called memory-module kits . Each kit contains one industry-standard, dual-inline memory module (DIMM). the server uses a noninterleaved memory configuration.

The server comes with a memory-module installed in connector J1, the connector nearest the rear of the server. Install additional memory modules in connectors J2, J3, and J4, in that order. If you mix DIMM sizes, install the largest sized DIMM in connector J1, the next largest sized DIMM in connector J2, and so forth.

Note:

1.  The memory-module kit sizes available for the  server are 64MB, 128MB, and 256MB. the  server supports a minimum of 128MB and a  maximum of 1GB of system memory.
2.  Install only 3.3 V, 168-pin, 8-byte DIMMs. Only  100 MHz, 72-bit, unbuffered, synchronous, error  correcting code (ECC), x8 configuration DIMM  memory is supported for the 64MB and 128MB  DIMMs. Only 100 MHz, 72-bit, registered,  synchronous, ECC, x4 configuration DIMM  memory is supported for the 256MB DIMMs.
3.  Mixing of DIMM types (registered and unbuffered)  is not supported. You can install 64MB  unbuffered and 128MB unbuffered DIMMs in the  same system, but neither 64MB unbuffered nor  128MB unbuffered DIMMs can be installed in a  system with 256MB registered DIMMs.
4.  Installing or removing memory modules changes  the configuration information in the server.  Therefore, after installing or removing a DIMM,  save the new configuration information in the  Configuration/Setup program. When you restart  the server, the system displays a message  indicating that the memory configuration has  changed. Start the Configuration/Setup program  and select Save Settings.  See 'Using the Configuration/Setup Utility Main Menu' for more information.

Refer to this illustration while you perform the steps in this procedure.

Note: The illustration shows only the processor board for simplicity, you do not need to remove the processor board to install a memory module.

•  Read 'Safety Information'.
•  Read the documentation that comes with the  option.

To install a memory module:

1.  Turn off the server and peripheral devices and  disconnect all external cables and power cords (see 'Preparing to Install Options'), then  remove the top cover (see 'Top Cover Removal').
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 from  the package.
4.  Install the memory module:

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

   1.  Locate the lowest-numbered, empty  memory-module connector on the processor  board.
   2.  Turn the memory module (DIMM) -6- so that the  pins align correctly with the connector -4-.
   3.  Insert the DIMM into the connector by pressing  on one edge of the DIMM and then on the other  edge 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 -5- are in the  closed position.
   6.  If a gap exists between the DIMM and the  retaining clips, 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.

5.  If you have other options to install or remove, do so  now, otherwise, go to Completing the Installation.
