Preface Intended Audience This document is written for system owners, customer service engineers, and self-maintenance customers using these systems and their hardware documentation. Document Structure This manual uses a structured documentation design. Topics are organized into sections for ease of reference. Each topic begins with an abstract. Next is an illustration or example, followed by descriptive text.
Icons. The icons shown below are used in illustrations for designating part placement in the system described. A shaded area in the icon shows the location of the component or part being discussed.
Chapter 1 Systems This chapter compares and describes the VAX 7000, VAX 10000, DEC 7000, and DEC 10000 systems.
1.1 VAX and Alpha AXP Compared Alpha AXP is a new RISC-based architecture which uses the world’s fastest microprocessor. For customers committed to the VAX architecture, VAX systems’ CISC-based architecture provides high performance. Both architectures run on the same platform. Table 1-1 1 Feature Comparison by Operating System Feature DEC OSF/1 AXP OpenVMS AXP OpenVMS VAX CPUs 1 to 6 1 to 6 1 to 6 Memory ________________64 Mbytes min.________________ 3.5 Gbytes max.
The world’s fastest microprocessor implements the Alpha AXP RISC-based architecture for the highest system performance through the 1990s. Alpha AXP systems owe their fast performance to the DECchip 21064 microprocessor which provides 64-bit addressing. The chip has been designed to accommodate high-performance features like multiple instruction issue and symmetric multiprocessing. DEC 7000 and 10000 systems are the server entries in this new family. VAX 7000 and 10000 systems have CISC-based architecture.
1.2 The Basic Platform All four systems share the same basic platform. This ensures protection for your hardware investment and enables simple upgrading from a VAX to an Alpha AXP system.
About the Basic Platform The platform contains the following components: • Cabinet control system • LSB 9-slot card cage with processor, memory, and IOP modules • Power and cooling systems • One or more plug-in units for I/O, disks, and batteries A removable media device, the RRD421 compact disk drive, is standard in DEC systems; a TF85 tape drive is optional in VAX systems. The media devices are next to the control panel in the main system cabinet.
1.3 Plug-In Units Plug-in units (PIUs) can be installed in the main and expander cabinets as shown in Figure 1-3. Both cabinets have space for PIUs in the bottom. The expander cabinet also has space for two PIUs in the top quadrants.
About Plug-In Units Plug-in units (PIUs) house options in the main and expander cabinets. Three buses may be added as PIUs (see Table 1-3): — XMI — Futurebus+ — VAXBI Storage and power PIUs include: — SCSI disks and tapes — DSSI disks — Batteries PIUs are located in the PIU expansion bays, known as quadrants (see Figure 1-3). The main cabinet has four PIU quadrants in its base, and each expander cabinet has six.
1.4 I/O Expansion The expander cabinet looks like the main cabinet, but without an LSB card cage or a control panel. Disk plug-in units may be installed in the space that would be occupied by the LSB card cage.
About the Expander Cabinet The expander cabinet has the same frame as the main cabinet; the contents, however, differ. The expander cabinet does not have an LSB card cage or a control panel, and it can have disk plug-in units in the upper part of the cabinet. The 7000 and 10000 systems have different cabinet variations (see Table 1-4). Expander Cabinet Configuration Rules • Each 7000 system can have one or two expander cabinets.
1.5 Power The power system consists of an AC input box, DC distribution box, and one to three power regulators. An N+1 redundant power system is available to ensure continued system availability in the event of a power regulator failure.
The N+1 redundant power system allows for higher system availability in the event of a power regulator failure. Systems can be configured with up to three power regulators per cabinet, ensuring that even the most heavily configured systems can keep operating if a power regulator fails. Optional system level UPS (uninterruptible power system) capability is available to support all elements in the CPU and I/O expander cabinets: CPU, memory, I/O channels and devices, and in-cabinet disk storage.
1.6 Console Console commands allow the user to configure and boot their system. They also enable access to I/O, memory, and environment parameters. All four systems have the same console commands.
Environment variables are a subset of console parameters that modify the recovery behavior of the system. An environment variable is a name associated with a value set and maintained by the console program and is manipulated using the set, show, and clear console commands. Environment variable values preserved across a system reset or power failure (written into EEPROM by the console) are called nonvolatile.
1.7 Power-Up Testing The systems are self-diagnosing. At power-up, the boot processor prints out self-test results. These extensive self-tests are automatically invoked at power-up. Figure 1-10 keys the selt-test display to the testing being done. Figure 1-10 Power-Up Test Sequence CPU CPU Memory Boot CPU 1 F E . + . . D . . . . C + . . .

Power-up tests are invoked without operator intervention at power-up and at any system initialization. The tests provide a thorough verification of system components prior to coming online with the console prompt (see Figure 1-10). 1 2 3 4 5 Processors run on-board self-tests and select a boot processor. Boot processor configures memory, runs CPU/memory tests, copies console to memory, and enters multiprocessor mode. CPU/multiprocessor tests are run, and the boot processor is determined again.
1.8 Upgrading from VAX to Alpha AXP VAX 7000 systems provide expansion and investment protection similar to the VAX 6000 family. You can add processors and upgrade as your computing needs grow. Figure 1-11 Investment Protection: VAX to Alpha AXP BXB-0487-93 And, finally, you don’t have to choose. Your investment is protected. You can move from the VAX architecture to Alpha AXP when your computing needs dictate. Your platform supports both architectures.
Chapter 2 Documentation This chapter covers the hardware documentation sets. In addition to the hardware documentation, there are document sets for your operating system and for your applications.
2.1 Documentation Map Hardware documentation fits into four pieces: user information, reference, maintenance material, and time-sensitive information. See Figure 2-1.
The hardware documentation set was designed and packaged with the user in mind. The books are targeted to arrive in the proper hands at the time they are needed. The most time-sensitive documents are the release notes and technical bulletins. Release notes contain the most current information about fixes and updates. Technical bulletins contain information on newly released features. Both ship with each system. See Section 2.3.
2.2 Time-Sensitive Information Time-sensitive information ships with each system: hardware release notes and any relevant technical bulletins. A CD-ROM also ships, containing the most current release of console-diagnostic files and documentation.
