8. Connect the riser-card power cable 1 to the PCI-X riser-card assembly 2.

If you have to remove the PCI-X riser-card assembly from the server, disconnect the riser-card power cable from the assembly first; then, grasp the front and rear edges of the assembly and lift the assembly out of the server.

If you have other devices to install or remove, do so now. Otherwise, go to “Completing the installation” on page 35.

Installing a memory module

The following notes describe the types of dual inline memory modules (DIMMs) that the server supports and other information that you must consider when you install DIMMs:

vThe server supports 512 MB, 1 GB, and 2 GB DIMMs, for a maximum of 8 GB of system memory. See http://www.lenovo.com/thinkserver for a list of memory modules that you can use with the server.

vThe amount of usable memory will be reduced depending on the system configuration. A certain amount of memory must be reserved for system resources. Use the system summary in the Configuration/Setup Utility program to view the total amount of installed memory and the amount of configured memory (see “Using the Configuration/Setup Utility program” on page 38).

vThe server comes with one 512 MB or 1 GB DIMM installed in DIMM connector 1 and an identical DIMM (the same size, speed, type, and technology) installed in DIMM connector 3.

vIf you install a pair of DIMMs in DIMM connectors 2 and 4, the size, speed, type, and technology of the DIMMs that you install in DIMM connectors 2 and 4 must match each other. However, they do not have to be the same size, speed, type, and technology as the DIMMs that are installed in DIMM connectors 1 and 3.

vYou can use compatible DIMMs from various manufacturers in the same pair.

vInstall only double-data-rate II (DDR II), PC2-5300, unbuffered synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC) DIMMs. These DIMMs must be compatible with the latest PC2-5300 SDRAM unbuffered DIMM specification.

vIf you install a pair of 2 GB DIMMs and a pair of other-size DIMMs, the 2 GB DIMMs must be installed as the first pair (in DIMM connectors 1 and 3).
