2 pSeries 610 Models 6C1 and 6E1 Technical Overview and Introductionfor keyboard, mouse, one parallel, and three serial. Only the rack-mounted Model 6C1 hasserial port one accessible from an RJ48 connection on front as well as the standard 9 pin porton the rear of the system. When one port is used, the other is disabled. The serial port 1,accessible on front, has a higher priority than serial port 1 on the rear.One or two POWER3-II 64-bit processors are connected to an IBM designed highperformance memory and system control chip set. These processors may be ordered in oneof the following two configurations: 375 MHz processor, including 4 MB of Level 2 (L2) ECC cache. 450 MHz processor, including 8 MB of L2 ECC cache.IBM has implemented copper technology in its SMP workstations and servers. Refer to“Copper and CMOS technology” on page 11 for more information.The memory can be expanded up to 8 GB for improved performance and exploitation of 64-bitaddressing, as used in large database applications.The Models 6C1 and 6E1 contain ten media bays. The six front-accessible, hot-swappabledisk drive bays can accommodate up to 218.4 GB of disk storage using 36.4 GB disk drives.Media bay 0 is occupied by the operator panel but has the default disk drive (non-hot swap)mounted behind the operator panel.Media bay 1 can be used for: An additional IDE CD-ROM drive A DVD-RAM drive An optional non-hot-swap disk (requires the media bay disk drive mounting kit to install aSCSI disk drive in the media bay) An optional media device, such as a 4 mm or 8 mm tape driveMedia bay 2 holds the default IDE CD-ROM drive or can hold a DVD-RAM drive, instead ofthe default CD-ROM.Media bay 3 is occupied by a diskette drive.A mouse or one of several national keyboards are used as input devices.For the rack-mounted Model 6C1, we recommend that you use the 7316-TF1 Flat PanelConsole in combination with the appropriate console switch to manage several systems in arack.To help ensure that strategic applications remain available 24 x 7, the Models 6C1 and 6E1feature an integrated service processor that constantly monitors the systems' vital signs. Inthe event of a malfunction, the service processor is capable of calling home by automaticallydialing out to an IBM service center, often before any problem is apparent to users or systemadministrators.Note: If you want to attach a 25-pin serial cable, you need to order the Serial PortConverter Cable, 9-Pin to 25-Pin (# 3925). This is not shipped with the system unit.An RJ45 to 9-pin converter cable is shipped automatically with every Model 6C1, whichcan be used for the RJ48 front serial port. The additional connections provided by theRJ48 connector are currently not used.
