    3. Test the system bus to PCI bus bridge and system bus to EISA bus bridge. If the PCI bridge fails or EISA bridge fails, an audible error beep code (3-3-1) sounds (Table 2–1). The power-up tests continue despite these errors. 4.
  • Page 53 4. Run exercisers on the drives currently seen by the system. Note This step does not ensure that all disks in the system will be tested or that any device drivers will be completely tested. Spin-up time varies for different drives, so not all disks may be on line at this point in the power-up sequence.

  • Page 55: Running System Diagnostics

    AlphaServer 1000A RBDs rely on exerciser modules, rather than functional tests, to isolate errors. The exercisers are designed to run concurrently, providing a maximum bus interaction between the console drivers and the target devices.

    The EISA bus is a superset of the well-established ISA bus and has been designed to be backward compatible with 16-bit and 8-bit architecture. Therefore, ISA modules can be used in AlphaServer 1000A systems, provided the operating system supports the device.

  • Page 106: Eisa Configuration Utility

    Before you install an option, check that the system supports the option. The version of the ECU that ships with AlphaServer 1000A systems accommodates 8 EISA slots. However, AlphaServer 1000A systems have only two EISA slots, slots 1 and 2.

  • Page 107: How To Start The Ecu

    • If you are configuring an EISA bus that contains both ISA and EISA options, refer to Table 5–7. 4. Locate the correct ECU diskette for your operating system. The ECU diskette is shipped in the accessories box with the system. Make a copy of the appropriate diskette, and keep the original in a safe place.

    Glossary 10Base-T Ethernet network IEEE standard 802.3-compliant Ethernet products used for local distribution of data. These networking products characteristically use twisted-pair cable. User interface to the console firmware for operating systems that require firmware compliance with the Windows NT Portable Boot Loader Specification. ARC stands for Advanced RISC Computing.
  • Page 176 backup cache A second, very fast cache memory that is closely coupled with the processor. bandwidth The rate of data transfer in a bus or I/O channel. The rate is expressed as the amount of data that can be transferred in a given time, for example megabytes per second.
  • Page 177 bystander A system bus node (CPU or memory) that is not addressed by a current system bus commander. byte A group of eight contiguous bits starting on an addressable byte boundary. The bits are numbered right to left, 0 through 7. cache memory A small, high-speed memory placed between slower main memory and the processor.
  • Page 178 cluster A group of networked computers that communicate over a common interface. The systems in the cluster share resources, and software programs work in close cooperation. cold bootstrap A bootstrap operation following a power-up or system initialization (restart). On Alpha based systems, the console loads PALcode, sizes memory, and initializes environment variables.
  • Page 179 data cache A high-speed cache memory reserved for the storage of data. Abbreviated as D-cache. DEC VET Digital DEC Verifier and Exerciser Tool. A multipurpose system diagnostic tool that performs exerciser-oriented maintenance testing. diagnostic program A program that is used to find and correct problems with a computer system. Digital UNIX A general-purpose operating system based on the Open Software Foundation technology.
  • Page 180 Error correction code. Code and algorithms used by logic to facilitate error detection and correction. EEPROM Electrically erasable programmable read-only memory. A memory device that can be byte-erased, written to, and read from. EISA bus Extended Industry Standard Architecture bus. A 32-bit industry-standard I/O bus used primarily in high-end PCs and servers.
  • Page 181 Flexible interconnect bridge. A converter that allows the expansion of the system enclosure to other DSSI devices and systems. field-replaceable unit Any system component that a qualified service person is able to replace on site. firmware Software code stored in hardware. fixed-media compartments Compartments that house nonremovable storage media.
  • Page 182 instruction cache A high-speed cache memory reserved for the storage of instructions. Abbreviated as I-cache. interrupt request lines (IRQs) Bus signals that connect an EISA or ISA module (for example, a disk controller) to the system so that the module can get the system’s attention through an interrupt.
  • Page 183 Medium attachment unit. On an Ethernet LAN, a device that converts the encoded data signals from various cabling media (for example, fiber optic, coaxial, or ThinWire) to permit connection to a networking station. memory interleaving The process of assigning consecutive physical memory addresses across multiple memory controllers.
  • Page 184 NVRAM Nonvolatile random-access memory. Memory that retains its information in the absence of power. Operator control panel. open system A system that implements sufficient open specifications for interfaces, services, and supporting formats to enable applications software to: • Be ported across a wide range of systems with minimal changes •...
  • Page 185 portability The degree to which a software application can be easily moved from one computing environment to another. porting Adapting a given body of code so that it will provide equivalent functions in a computing environment that differs from the original implementation environment.
  • Page 186 reliability The probability a device or system will not fail to perform its intended functions during a specified time. responder In any particular bus transaction, memory, CPU, or I/O that accepts or supplies data in response to a command/address from the system bus commander. RISC Reduced instruction set computer.
  • Page 187 User interface to console firmware for operating systems that expect firmware compliance with the Alpha System Reference Manual (SRM). storage array A group of mass storage devices, frequently configured as one logical disk. StorageWorks Digital’s modular storage subsystem (MSS), which is the core technology of the Alpha SCSI-2 mass storage solution.
  • Page 188 test-directed diagnostics (TDDs) An approach to diagnosing computer system problems whereby error data logged by diagnostic programs resident in read-only memory (RBDs) is analyzed to capture information about the problem. thickwire One-half inch, 50-Ohm coaxial cable that interconnects the components in many IEEE standard 802.3-compliant Ethernet networks.
  • Page 189 write back A cache management technique in which data from a write operation to cache is written into main memory only when the data in cache must be overwritten. write-enabled Indicates a device onto which data can be written. write-protected Indicates a device onto which data cannot be written.
