Netfinity 5600 Memory upgrades

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.

NOTE: To remove a memory-module kit, reverse this procedure.

The server comes with a DIMM installed on the processor board in connector J1. When adding additional memory, install the DIMMs in the following order:

• Install the largest size memory DIMM in connector J1. (J1 is the memory connector farthest from the microprocessor.)
• If you are installing two memory DIMMs, the second should be installed in connector J4. (J4 is the memory connector closest to the microprocessor.)
• If you are installing three memory DIMMs, the second should be installed in connector J4 and the third in connector J3.
• If you are installing four memory DIMMs, the second should be installed in connector J4, the third in connector J3, and the fourth in connector J2.

NOTE: Except for connector J1, the size of the DIMM in each connector is unimportant.

Refer to the following table for examples of typical memory configurations:

NOTES:
1. The Netfinity 5600 server supports 128 MB, 256 MB, 512 MB, and 1 GB DIMMs. The server supports a minimum of 128 MB and a maximum of 4 GB of system memory. Only 133 MHz, 3.3 V, 168-pin, 8-byte, 72-bit registered, synchronous-dynamic-random-access memory (SDRAM), error correcting code (ECC) with x4 configuration DIMM memory complying with PC 133 Registered DIMM Specification, Revision 1.0 or later is supported.

2. Installing or removing DIMMs changes the configuration information in the server. Therefore, after installing or removing a DIMM, you must save the new configuration information in the Configuration/Setup Utility program. When you restart the server, the system displays a message indicating that the memory configuration has changed. Start the Configuration/Setup Utility program and select Save Settings. See "Using the System Configuration Utility main menu" in the HMM for more information.

Before you begin

• Read “Safety information” in the HMM.
• Read the documentation that comes with the option.

To install a DIMM

1. Turn off the server and peripheral devices and disconnect all external cables and power cords (see “Preparing to install options” in the HMM); then remove the cover. See “Removing the left-side cover (tower model)” in the HMM or “Removing the cover (rack model)” in the HMM.
2. Locate the DIMM connectors on the processor board. Determine the DIMM connector into which you will install the DIMM. (See the notes at the beginning of this procedure.)
3. Touch the static-protective package containing the DIMM to any unpainted metal surface on the server. Then, remove the DIMM from the package.

NOTE: To avoid breaking the retaining clips or damaging the DIMM connectors, handle the clips gently.

4. Install the DIMM:

a. Turn the DIMM 1 so that the pins align correctly with the connector 5.
b. 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. Be sure that the retaining clips 2 snap into the closed positions.
c. Make sure the retaining clips are in the closed position. 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.
d. Repeat these steps for each DIMM that you install.

5. If you have other options to install or remove, do so now; otherwise, go to “Completing the installation”.
