Memory installation - Netfinity 7100, 7600

Content

Before you continue with the memory-installation procedure, review the following:

• Review the information in "Before you begin" in the HMM.
• All the DIMMs installed in each set must be the same size and speed, but all the sets do not have to contain DIMMs of the same size and speed.
• The memory board contains 16 DIMM connectors and supports 4-way memory interleaving.
• Install only 3.3 V, 168-pin, 8-byte, registered DIMMs. Only 100 MHz, 72-bit, registered, synchronous, error correcting code (ECC), SDRAM configuration DIMM memory is supported for the 128 MB, 256 MB, 512 MB and 1 GB (when available) DIMMs.
• If you install 4 GB of memory, some of the memory is reserved for system resources. The amount reserved for system resources depends on the configuration of the server.
• If you install 16 GB of memory, the Configuration/Setup Utility will display the memory that is usable by the network operating system. This amount of memory might differ from the amount of memory you have installed.
• 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. Refer to "Using the Configuration/Setup Utility program" in the HMM for more information.
• Install the DIMMs in the order provided in Table 7.
• For the locations of the DIMM connectors, see "Memory board component locations".

Refer to the following illustration when installing memory.

1. Pop rivets
2. Processor housing cover
3. DIMM
4. Memory board

To install a memory module:

Before you begin

• Read "Safety information" in the HMM.
• Read the documentation that comes with your option.

1. Review "Before you begin" in the HMM.
2. Turn off the server and all attached devices. Disconnect external cables and power cords and remove the top cover.
3. Pull up the two pop rivets on the processor housing cover and remove the cover from the processor housing.
4. Remove the memory board assembly:

a. Lift up on the memory board assembly and remove it from the server.
b. Place the memory board assembly on a static-protective surface, such as the static-protective package in which the option came.

5. Locate the DIMM connectors on the memory board. Determine the DIMM connectors into which you will install the DIMMs. (See the notes at the beginning of this procedure.)
6. Touch the static-protective package containing the DIMM option 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.

7. To install the DIMMs, repeat the following steps for each DIMM that you install.

a. Turn the DIMM so that the pins align correctly with the DIMM connector.
b. Insert the DIMM by pressing the DIMM straight into the connector. Be sure that the retaining clips snap into the closed position.

8. Install the memory board assembly:

a. Hold the memory board assembly and align it over the memory board connector.
b. Insert the memory board assembly into the connector.

9. Install the processor housing cover and push the two pop rivets down to secure the cover.
10. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" in the HMM.
