Document Structure This manual uses a structured documentation design. Topics are organized into small sections for efficient reference. Each topic begins with an ab­ stract. You can quickly gain a comprehensive overview by reading only the abstracts. Next is an illustration, which also provides quick reference. Last in the structure is a procedure. This manual has eight chapters and one appendix, as follows: · Chapter 1, Configuration Rules, gives you information about con­ figuring each part of the system. · Chapters 2 through 8 provide removal and replacement instructions for each field­replaceable unit: · Chapter 2, Cabinet Doors and Panels · Chapter 3, Cabinet Control System · Chapter 4, Power and Cooling Systems · Chapter 5, LSB Card Cage · Chapter 6, I/O Plug­In Units · Chapter 7, Disk Plug­In Units · Chapter 8, Battery Plug­In Unit · Appendix A contains a quick reference to the location of each field­ replaceable unit. viii Conventions Used in This Document Terminology. Unless specified otherwise, the use of "system" refers to either a DEC 7000 AXP or VAX 7000 system. The DEC 7000 AXP systems use the Alpha AXP architecture. References in text use DEC 7000 to refer to DEC 7000 AXP systems. When a discussion applies to only one system, an icon is used to highlight that system. Otherwise, the discussion applies to both systems. Thus, the abstract for a module that applies only to DEC 7000 systems would look like this: Book titles. In text, if a book is cited without a product name, that book is part of the hardware documentation. It is listed in Table 1 along with its order number. 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 lo­ cation of the component or part being discussed. Part numbers. Part numbers are listed in Appendix A of this manual. Documentation Titles Table 1 lists the books in the DEC 7000 and VAX 7000 documentation set. Table 2 lists other documents that you may find useful. DEC 7000 This section shows a sample boot of Open VMS Alpha AXP from the RRD42 CD drive for DEC 7000 systems.

Configura­ tion of these components is discussed in this chapter. Configuration Rules 1­3 About the Main Cabinet The main cabinet, H9F00AA/AB/AC, contains the following components: · Cabinet control system · LSB card cage with processor, memory, and IOP modules · Power and cooling systems · One or more plug­in units for: · I/O · Disks · Batteries A removable media device (RRD421 in DEC 7000 systems; TF85 in VAX 7000 systems) is optional. If used, it is mounted next to the control panel in the main system cabinet. Variants of the main cabinet are listed in Table 1­1. Table 1­1 Main Cabinet Variants Part Number Regulator H9F00AA 120/208 V, 60 Hz H9F00AB 220­240/380­415 V, 50 Hz H9F00AC 202 V, 50­60 Hz 1 The RRD42 requires a dedicated KZMSA port in an XMI plug­in unit in the main cabinet. 1­4 Configuration Rules 1.2 Expander Cabinet Figure 1­2 Expander Cabinet The expander cabinet looks like the main cabinet, but without an LSB card cage or a control panel. Disk plug­in units may be in­ stalled in the space that would be occupied by the LSB card cage. Configuration Rules 1­5 About the Expander Cabinet The expander cabinet, H9F00BA/BB/BC, is similar to the main cabinet. The second letter of each variant identifies voltage (see Table 1­1 for these voltages). The expander cabinet frame is identical to 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 plug­in units in the upper part of the cabinet. Expander Cabinet Configuration Rules · Each system may have a maximum of two expander cabinets. The first expander cabinet is placed to the right of the system cabinet and the second to the left. See Figure 1­3. · The expander cabinet may contain a removable media device (RRD421 in DEC 7000 systems; TF85 in VAX 7000 systems). If used, it is located in the front of the expander cabinet, at the top. · The configuration rules for the lower quadrants of the system cabinet also apply to the lower quadrants of the expander cabinet. · The only plug­in units that may be installed in the upper quadrants of the expander cabinet are disk plug­in units. Figure 1­3 System With Two Expander Cabinets (Front View) 1 The RRD42 requires a dedicated KZMSA port in an XMI plug­in unit in the same expander cabinet. 1­6 Configuration Rules 1.3 Power System Figure 1­4 Power System The power system consists of the AC input box, DC distribution box, and power regulators. This section includes configuration in­ formation for power regulators. Configuration Rules 1­7 About the Power System · The power system consists of the AC input box, DC distribution box, and a minimum of one and a maximum of three power regulators. (See Figure 1­4.) · The maximum system configuration requires two regulators; the third is for optional redundant power. · Power regulators cannot be warm swapped. · Each plug­in unit (with the exception of the battery plug­in unit) has a local power supply that generates the needed +5V and other miscella­ neous DC voltages. Power Regulator Configuration When viewed from the front of the system cabinet, the leftmost power regulator (closest to the LSB card cage) corresponds to phase A, the middle with phase B, and the rightmost with phase C (see Figure 1­4). Power regulators are configured in manufacturing starting closest to the LSB card cage and working to the right. This platform, with one regulator installed, constitutes a true single­phase load. The load currents in three­phase power distribution need to be bal­ anced. If necessary, reconfigure the regulators (and batteries, if the cabinet contains a battery plug­in unit) in multiple­system installations to balance the three­phase currents and to reduce stresses in the common neutral conductor. 1­8 Configuration Rules 1.4 LSB Card Cage Figure 1­5 LSB Card Cage (Top View) Table 1­2 Memory Module Placement The LSB card cage contains nine module slots. The minimum con­ figuration is a processor module in slot 0, a memory module in slot 7, and the I/O port module in slot 8. This section gives placement rules for other configurations. Number of Processor Modules Memory Module: 1st 2nd 3rd 4th 5th 6th 7th 1 7 1 6 2 5 3 4 2 7 6 2 5 3 4 · 3 7 6 5 3 4 · · 4 7 6 5 4 · · · 5* 7 6 5 · · · · 6* 7 6 · · · · · *Insert these processor modules after all memory modules have been inserted. Configuration Rules 1­9 About the LSB Card Cage · The LSB card cage has slots for nine modules. These modules are a combination of processor (KN7AAAA or KA7AA­AA), memory (MS7AAAA, BA, CA, DA), and I/O port (IOP, E2044AA) modules. · The maximum number of processor modules is six. · The maximum number of memory modules is seven. Memory modules may reside in slots 1 through 7 only. · The maximum amount of memory in a DEC 7000 system is 14 Gbytes; in a VAX 7000 system it is 3.5 Gbytes. Memory module sizes are 64 Mbyte (MS7AAAA), 128 Mbyte (MS7AABA), 256 Mbyte (MS7AA CA), and 512 Mbyte (MS7AADA). All but the 64­Mbyte module sup­ port two­way interleaving. Mixed sizes of memory modules may be in­ stalled in the LSB card cage. · Each system must have one IOP module, which must reside in slot 8. · The minimum configuration is one processor module, one memory module, and one IOP module. In this configuration, the processor mod­ ule must reside in slot 0 and the memory module in slot 7. Module Placement Rules Due to the speed of the LSB bus, these rules must be followed. The goal is to keep all modules as close together as possible. This is best accomplished by alternating memory modules between the front and rear of the card cage. Configure modules in this order: 1. Check that the IOP module is in slot 8. 2. Place the first four processor modules starting in slot 0 through slot 3. 3. Next configure memory modules as shown in Table 1­21. 4. Insert any remaining processor modules in open slots with the highest node ID numbers. (The node ID number is the same as the slot num­ ber.) 5. Install filler modules in any unused slots to ensure proper airflow. 1 Table 1­2 shows the slot in which each memory module is installed depending on the num­ ber of processor modules in the system. For example, if the system contains two processor modules and three memory modules, the first memory module is installed in slot 7, the sec­ ond in slot 6, and the third in slot 2. 1­10 Configuration Rules 1.5 I/O Interface Figure 1­6 I/O Interface The I/O interface consists of the IOP module in the LSB card cage and the I/O cables, which connect the IOP module to the I/O bus. Configuration Rules 1­11 About the I/O Interface The I/O interface consists of the I/O port (IOP) module in slot 8 of the LSB card cage and two unidirectional cables for each I/O channel. The IOP module can accommodate a maximum of four I/O channels.
