Netfinity 5500 - Memory-Module Kits

Applicable to: World-Wide

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). Your server uses a noninterleaved memory configuration.

Your 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.

Notes 1. The memory-module kit sizes available for your server are 64 MB, 128 MB, and 256 MB. Your server supports a minimum of 128 MB and a maximum of 1 GB 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 64 MB and 128 MB DIMMs. Only 100 MHz, 72-bit, registered, synchronous, ECC, x4 configuration DIMM memory is supported for the 256 MB DIMMs. 3. Mixing of DIMM types (registered and unbuffered) is not supported. You can install 64 MB unbuffered and 128 MB unbuffered DIMMs in the same system, but neither 64 MB unbuffered nor 128 MB unbuffered DIMMs can be installed in a system with 256 MB registered DIMMs. If your server has unbuffered DIMMS, jumper pins 1 and 2 on J12. If your server has registered DIMMS, jumper pins 2 and 3 on J12. See diagram below. 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.

Before you begin: Read "Safety Information". Read the documentation that comes with your 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.

a. Locate the lowest-numbered, empty memory-module connector on the processor board.
b. Turn the memory module (DIMM) 6 so that the pins align correctly with the connector 4.
c. 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.
d. Repeat the preceding step to make sure the DIMM is seated correctly.
e. Make sure the retaining clips 5 are in the closed position.
f. 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.
g. 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".

6. 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.
