6. If the drive is a SCSI tape drive, detach the SCSI terminator from the top ofthe CD/DVD or tape-drive bay (depending on the server model); then,disconnect the SCSI signal cable from the SCSI adapter and remove the cablefrom the server:a. Remove the fan-bracket assembly (see “Removing the fan-bracketassembly” on page 77).b. Remove the DIMM air baffle (see“Removing the DIMM air baffle” on page36 ).c. Lift the riser-card assembly from the server.d. Disconnect the cable from the connector on the SCSI adapter.e. Temporarily disconnect the hard disk drive backplane signal cable from thesystem board (see the illustration on page “System-board internal cableconnectors” on page 19 for the location of the hard disk drive backplanesignal connector).f. Remove the hard disk drive backplane signal cable and SCSI cable fromthe cable clamp. See the illustration on page 56 for the location of the cableclamp.g. Replace the hard disk drive backplane signal cable in the cable clamp;then, reconnect the hard disk drive backplane signal cable to the connectoron the system board (J92).7. Open the tape drive tray release latch.8. Gently pull the drive and cables out of the bay.Note: On a 3.5-inch model server, gently pull the drive cables through the slotin the left side of the bay and out the front of the server, or as far as they willgo (the terminator on a SCSI tape cable does not go through the slot in theside of the bay). If the drive is a SCSI drive, disconnect the SCSI cable fromthe rear of the tape drive and gently pull it back through the slot and into theserver; then, lift the cable out of the server.9. If you are not installing another drive in the bay, install a filler panel or panelsin the bay. If you removed a SCSI tape drive, reinstall the DIMM air baffle andriser-card assembly (see “Installing the DIMM air baffle” on page 37 and“Installing the riser-card assembly” on page 33).10. Install the fan-bracket assembly (see “Installing the fan-bracket assembly” onpage 79).11. Replace the server cover.Installing a microprocessorThe following notes describe the type of microprocessor that the server supportsand other information that you must consider when installing a microprocessor:v The server supports certain Intel Xeon dual-core or quad-core flip-chip land gridarray 771 (FC-LGA 771) microprocessors, which are designed for the LGA771socket. See http://www.ibm.com/servers/eserver/serverproven/compat/us/ for alist of supported microprocessors.Important: Dual-core and quad-core microprocessors are not interchangeableand cannot be used in the same server. For example, if the server has adual-core microprocessor, you cannot install a quad-core microprocessor as thesecond microprocessor. Use the Configuration/Setup Utility program to determinethe type and speed of the microprocessor that is currently installed in the server.At the time of this publication, the following IBM System x3650 server modelscome with quad-core microprocessors:62 System x3650 Type 7979: User’s Guide
