  • Page 23 This system is designed to fully exploit the potential of the Alpha 21264 chip by using a switch-based (or point-to-point) interconnect system. With a traditional bus design, the processors, memory, and I/O modules share the bus. As the number of bus users increases, the transactions interfere with one another, increasing latency and decreasing aggregate bandwidth.

  • Page 24: System Enclosures

    System Enclosures The Compaq AlphaServer ES40 family consists of a standalone tower, a pedestal with expanded storage capacity, and a cabinet. Figure 1–2 Compaq AlphaServer ES40 Systems Rackmount Pedestal Tower PK0212 Compaq AlphaServer ES40 Service Guide...
  • Page 25 Model Variants AlphaServer ES40 systems are offered in two models. The entry-level model provides connectors for four DIMMs on each of the memory motherboards (MMBs) and connectors for six PCI options on the PCI backplane. To upgrade from Model 1 to Model 2, you replace the PCI backplane and the four memory motherboards.

  • Page 34: Cpu Card

    CPU Card An AlphaServer ES40 can have up to four CPU cards. In addition to the Alpha 21264 chip, the CPU card has a 4-Mbyte second-level cache and a 2.2V DC-to-DC converter with heatsink that provides the required voltage to the Alpha chip. Power-up diagnostics are stored in a flash SROM on the card.
  • Page 35 The 21264 microprocessor is a superscalar CPU with out-of-order execution and speculative execution to maximize speed and performance. It contains four integer execution units and dedicated execution units for floating-point add, multiply, and divide. It has an instruction cache and a data cache on the chip. Each cache is a 64 KB, two-way, set associative, virtually addressed cache that has 64-byte blocks.

  • Page 43: Remote Management Console (Rmc)

    1.10.2 Remote Management Console (RMC) The remote management console (RMC) provides a mechanism for remotely monitoring a system and manipulating it on a very low level. It also provides access to the repository for all error information in the system. This provides the operator, either remotely or locally, with the ability to monitor the system (voltages, temperature, fans, error status) and manipulate it (reset, power on/off, halt) without any interaction on the part of the operating system.

  • Page 44: Power Supplies

    The power supplies provide power to components in the system box. The number of power supplies required depends on the system configuration. Figure 1–12 Power Supplies Tower Pedestal/Rack 1 1 1 2 2 2 PK0207 1-24 Compaq AlphaServer ES40 Service Guide...
  • Page 45 One to three power supplies provide power to components in the system box. The system supports redundant power configurations to ensure continued system operation if a power supply fails. See Chapter 6 for power supply configurations. When more than one power supply is installed, the supplies share the load. The power supplies select line voltage automatically (120V or 240V and 50 Hz or 60 Hz).

  • Page 54: Questions To Consider

    See Chapter 7. ½ If the operating system has crashed and rebooted, the CCAT (Compaq Crash Analysis Tool), the Compaq Analyze service tools (to interpret error logs), the SRM crash command, operating system exercisers, and DEC VET can be used to diagnose system problems.

  • Page 55: Diagnostic Tables

    Diagnostic Tables System problems can be classified into the following five categories. Using these categories, you can quickly determine a starting point for diagnosis and eliminate the unlikely sources of the problem. 1. Power problems—Table 2–1 2. No access to console mode—Table 2–2 3.

  • Page 56: Power Problems

    If AC power is present, use the RMC Chapter 7 env command to check environmental status. Appendix B Check jumper J26. If the system must be kept running, this jumper can be positioned to override an overtempera- ture condition. Compaq AlphaServer ES40 Service Guide...

  • Page 61: Service Tools And Utilities

    The Tru64 UNIX, OpenVMS, and Microsoft Windows NT operating systems provide fault management error detection, handling, notification, and logging. The primary tool for error handling is Compaq Analyze, a fault analysis utility designed to analyze both single and multiple error/fault events. Compaq Analyze uses error/fault data sources other than the traditional binary error log.

    DIMM Isolation Procedure Use the procedure in this section to isolate the failing DIMM. 1. Find the failing array by using the failing address and the Array Address Registers (AARs—see Appendix D). Use the AAR base address and size to create an Address range for comparing the failing address.
