Netfinity 5500 memory module kits
Adding memory to your server is an easy way to make programs run faster. You can increase the amount of memory in your server by installing options called memory-module kits. Each kit contains one industry-standard, dual-inline memory module (DIMM).

Upgrade NOTES:

• The Netfinity 5500 server uses a noninterleaved memory configuration, and supports a minimum of 128MB and a maximum of 1GB of RAM.
• It 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.
• The memory-module kit sizes available for your server are 64MB, 128MB, and 256MB.
• If you mix DIMM sizes, install the largest sized DIMM in connector J1, the next largest DIMM in connector J2, and so forth.
• Install only 3.3V, 168-pin, 8-byte DIMMs.
• Only 100MHz, 72-bit, unbuffered, synchronous, error correcting code (ECC), x8 configuration DIMM memory is supported for the 64MB and 128MB DIMMs.
• Only 100MHz, 72-bit, registered, synchronous, ECC, x4 configuration DIMM memory is supported for the 256MB DIMMs.
• 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.
• If your server has unbuffered DIMMS, jumper pins 1 and 2 on J12 (see diagram below).
• If your server has registered DIMMS, jumper pins 2 and 3 on J12 (see diagram below).

How to install a memory module

1. Read the "Safety Information" in your User's Guide, and read the documentation that comes with your memory option.
2. Turn off the server and peripheral devices and disconnect all external cables and power cords; then remove the top cover.
3. Locate the memory-module connectors on the memory board.
4. 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. Click here for information on ESD sensitive devices.
5. Locate the lowest-numbered, empty memory-module connector on the processor board.
6. Turn the memory module (DIMM) so that the pins align correctly with the connector.
7. 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. To avoid breaking the retaining clips or damaging the memory-module connectors, handle the clips gently. Repeat this step to make sure the DIMM is seated correctly.
8. Make sure the retaining clips are in the closed position.
9. 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.
10. Repeat these steps for each memory module that you install.
11. If you have other options to install or remove, do so now; otherwise, reinstall the system cover and cables.
12. 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 F1 Configuration/Setup Utility program at bootup. When you restart the server, the system will display a message indicating that the memory configuration has changed. Start the Configuration/Setup program and select Save Settings.
13. Installation is complete.

Troubleshooting NOTE: If after adding one or more supported registered DIMMS in the system, POST results in a 1-3-1 beep code, no video, and one or more DIMM error LEDs (CR8, CR9, CR10, CR11) on the Processor Board are activated, OR there is no video upon power up of the system, and the system cooling fans function, then check jumper J12 on the system board. If your server has unbuffered DIMMS, a jumper should be on pins 1 and 2. If your server has registered DIMMS, a jumper should be on pins 2 and 3.
