12. Align the rails on the tape drive with the guides in the drive bay; then, slide thetape drive into the drive bay until the rails click into place.13. Connect power and signal cables to the drive and the connectors on thesystem board (see “Internal cable routing and connectors” on page 40 for moreinformation).If you have other devices to install or remove, do so now. Otherwise, go to“Completing the installation” on page 109.Installing a memory moduleThe following notes describe the types of DIMMs that the server supports and otherinformation that you must consider when you install DIMMs.v When you install or remove DIMMs, the server configuration informationchanges. When you restart the server, the system displays a message thatindicates that the memory configuration has changed.v The server supports only industry-standard double-data-rate 3 (DDR3), 800,1066, 1333, or 1600 MHz, PC3-6400, PC3-8500, PC3-10600, or PC3-12800registered or unbuffered, synchronous dynamic random-access memory(SDRAM) dual inline memory modules (DIMMs) with error correcting code (ECC).See http://www.ibm.com/servers/eserver/serverproven/compat/us/ for a list ofsupported memory modules for the server.– The specifications of a DDR3 DIMM are on a label on the DIMM, in thefollowing format.ggggg eRxff PC3v-wwwwwm-aa-bb-ccdwhere:ggggg is the total capacity of the DIMM (for example, 1GB, 2GB, or 4GB)eR is the number of ranks1R = single-rank2R = dual-rank4R = quad-rankxff is the device organization (bit width)x4 = x4 organization (4 DQ lines per SDRAM)x8 = x8 organizationx16 = x16 organizationv is the SDRAM and support component supply voltage (VDD)Blank = 1.5 V specifiedChapter 2.
