three of the most important features in computer design are reliability, availability,and serviceability (ras).the ras features help to ensure the integrity of the data that is stored on your computer; the availability of the computer when you need it; and the ease with which you can diagnose and repair problems.

    the following is an abbreviated list of the ras features that your computer supports.

    many of these features are explained in the later chapters of this publication.

    1 reliability features

    1 boot block recovery

    2 cooling fans with speed-sensing capability

    3 customer upgradable basic input/output system (bios)

    4 error code correction (ecc) front-side buses (fsbs)

    5 ecc l2 cache

    6 ecc memory

    7 parity checking on the small computer system interface (scsi) and peripheral component interconnect (pci) buses

    8 advanced configuration and power interface (acpi)

    9 power-on self-test (post)

    10 rambus dynamic random access memory (rdram) with serial presence detect (spd)

    2 availability features

    1 advanced desktop management interface (dmi) features

    2 alert on lantm capability

    1 chassis intrusion

    2 operating system (os) suspensions2

    3 auto-restart initial program load (ipl) power supply

    4 automatic error retry or recovery

    5 automatic computer restart

    6 automatic restart after power failure

    7 built-in, menu-driven configuration programs

    6 diagnostic support of ethernet adapters

    7 error codes and messages

    8 processor serial number access

    9 read-only memory (rom) checksums

    10 vital product data (vpd); includes serial number information and replacement part numbers, stored in nonvolatile memory, for easier remote maintenance
