7. Replace the tray and secure the tray to the system board with screws from the hardware kit. 8. Set any jumpers or switches on the hard disk drive, if this requirement is specified on the drive label or in the documentation that comes with the drive. 9. Place the hard disk drive into the tray and, from the rear edge of the hard disk drive, push it into the connector on the riser card until the hard disk drive moves past the lever at the back of the tray. The hard disk drive clicks into place. 10. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 90. Installing memory modules You can increase the amount of memory in the blade server by installing additional memory-module options. The following items describe the types of dual inline memory modules (DIMMs) that the blade server supports and other information that you must consider when installing DIMMs: v The system board contains four DIMM connectors and supports two-way memory interleaving. v As of the date of this publication, the blade server supports a minimum of 512 MB and a maximum of 8 GB of system memory (depending on the blade server model). The DIMM options available are 256 MB, 512 MB, 1 GB, and 2 GB, with the following exceptions: - 256 MB DIMMs are not supported by the 8842-4Tx model. - 2 GB DIMMs are not supported by the 8842-21x, 8842-E1x, 8842-E2x, 8842-41x, and 8842-4Ax models. v Install only 2.5 V, 184-pin, double-data-rate (DDR), PC2700, registered synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC) DIMMs. For a current list of supported DIMMs for the blade server, go to http://www.ibm.com/pc/us/compat/. v Install DIMMs in a matched pair. Each pair must be the same size, speed, type, and technology. You can mix compatible DIMMs from various manufacturers. The second pair of DIMMs does not have to be the same size as the first pair. v After you install or remove a DIMM, the new configuration information is automatically saved in the blade server firmware code. The following illustration shows how to install DIMMs on the system board. DIMM socket 4 (J40) DIMM socket 3 (J32) DIMM socket 2 (J28) DIMM socket 1 (J25) Chapter 9. Installing options 77
