C-1 ix ------------------------------------------------------------ Preface This manual provides the information that you will need to maintain the BA42B Enclosure when used with the VAX 4000 Model 100/100A/105A systems. It contains information about the enclosure, installation information, and procedures for servicing field replaceable units (FRUs). Audience This manual is for Digital(TM) Services personnel who provide support and maintenance for systems that use this enclosure. It is also for customers who have a self-maintenance agreement with Digital Equipment Corporation. Users of this manual must have experience in replacing hardware components. Structure of This Manual This manual is divided into three chapters, three appendixes, a glossary, and an index: · Chapter 1 provides an overview of the system enclosure and describes the controls, mass storage areas and capacity, signal distribution, power distribution, input and output connections, and configuration guidelines. · Chapter 2 provides site preparation information and describes how to install the systems that use the enclosure. · Chapter 3 provides instructions on removing and replacing FRUs. xi · Appendix A gives the pin specifications for the ports on the back of the system unit. · Appendix B gives a list of the related documents. · Appendix C gives a list of recommended spare parts. xii Conventions The following conventions are used in this manual: ------------------------------------------------------------ Convention Description ------------------------------------------------------------ Ctrl/x Ctrl/x indicates that you hold down the Ctrl key while you press another key or mouse button (indicated here by x). x A lowercase italic x indicates the generic use of a letter. For example, xxx indicates any combination of three alphabetic characters. italic type Italic type emphasizes important information, indicates variables, and indicates the complete titles of manuals. nn nnn.nnn nn A space character separates groups of 3 digits in numerals with 5 or more digits.

It gives information on the following: · Preparing the site · Unpacking the system · Installing a BA42B system Since the back of the enclosure differs from model to model, the portion of this chapter devoted to the actual installation of the system is divided into two sections; the first covers the VAX 4000 Model 100, and the second section covers the VAX 4000 Models 100A/105A. 2.1 Preparing the Site Before you unpack the BA42B system, verify the physical, environmental, and electrical requirements described in this section. 2.1.1 Enclosure Dimensions Figure 2-1 shows the dimensions of the BA42B Enclosure. ------------------------------------------------------------ Caution ------------------------------------------------------------ The container and enclosure together typically weigh 20.50 kilograms (kg) (45 pounds [lb]). Two people are required to handle the container. ------------------------------------------------------------ Installation Procedures 2-1 Installation Procedures 2.1 Preparing the Site Figure 2-1 BA42B Dimensions The dimensions of the container are as follows: · Height = 35.3 cm (14.0 inches) · Width = 61.1 cm (24.0 inches) · Depth = 51.0 cm (20.0 inches) 2.1.2 Additional Equipment When you are installing additional equipment, follow these guidelines: · Make sure that there is sufficient space for the terminals and other peripheral equipment. · Make sure that you keep the mass storage devices in an area that has the same temperature and humidity as the computer area (see Table 2-1). · When you plan the cable routing for multiple-terminal systems, consider factors such as safety, convenience, future expansion, and cost. Label and install the cables before you install the system. 2-2 Installation Procedures Installation Procedures 2.1 Preparing the Site 2.1.3 Operating Environment Computer systems in office areas are subject to electrostatic discharge (ESD), temperature changes, and humidity. To install the system in the correct environment, follow these guidelines: · Install the system in a well-ventilated area where the temperature and humidity ranges listed in Table 2-1 are maintained during the year. · Do not place a system near heating or cooling devices, large windows, or doors that open to the outside. Rapid changes of temperature can affect the performance of the system. · Place the system in an area where the air contains a minimum of dust and other abrasive contaminants. 2.1.4 Electrostatic Discharge ESD can cause system failures and loss of data. To minimize the buildup of static electricity, follow these guidelines: · Maintain a relative humidity level of at least 40%. · Place the system away from busy corridors. · Carpet in the computer area is not recommended. However, if you want to use carpet, antistatic carpet is recommended. When carpet is already in use, put an antistatic mat under the system. 2.1.5 Heat Dissipation The heat dissipated by a BA42B Enclosure system depends on the model number of the system, but is typically 410 British thermal units/hour (Btu/h). Installation Procedures 2-3 Installation Procedures 2.1 Preparing the Site 2.1.6 Temperature, Humidity, and Altitude Ranges Table 2-1 gives the operating, nonoperating, and storage ranges for the temperature, humidity, and altitude for BA42B Enclosure systems.

When installing RF31T/RF35/RF36 disk drive options, the DSSI ID must be set to an ID that is not used by any other DSSI device in the system. (Refer to the VAX 4000 Models 100, 100A, 105A KA52/53 CPU System Maintenance manual for further information.) To set the DSSI ID on RF31T/RF35/RF36 disk drive options, follow these steps: 1. Locate the DSSI ID jumper on the disk drive (see Figure 3-24). Table 3-2 shows the DSSI ID jumper combinations.

Connect the DSSI cable to the CPU module. 5. Connect the SCSI cable (17-02944-01) to the CPU module (refer to Figure 3-44 for the location of the SCSI cable). 6. Connect the power cable to the CPU module (refer to Figure 3-44 for the location of the power cable). 7. Install the MS44 and MS44L memory modules that you removed from the original CPU module. Follow the steps in Section 3.2 in reverse order to install the memory modules. 8. Install the DSW42 logic board, and connect the DSW42 input/output cable if fitted. Follow the steps in Section 3.15.1 and Section 3.15.2 in reverse order to install the logic board and cable. 3-72 Removing and Replacing Field Replaceable Units Removing and Replacing Field Replaceable Units 3.18 Replacing the CPU Module 9. Install the DHW42 logic board, and connect the DHW42 input/output cable if fitted. Follow the steps in Section 3.16.1 and Section 3.16.2 in reverse order to install the logic board and cable. 10. Install the upper and lower drive-mounting shelf combination. Follow the steps in Section 3.11 in reverse order to install the drive-mounting shelf combination. 11. Install the enclosure cover. Follow the steps in Section 3.1 in reverse order to install the cover. 3.19 Removing the Power Supply ------------------------------------------------------------ Note ------------------------------------------------------------ In VAX 4000 systems, the power supply (30-35042-01) is a single FRU. It does not have any replaceable components. ------------------------------------------------------------ To remove the power supply from the BA42B Enclosure, follow these steps: 1. Remove the ac power. 2. Remove the enclosure cover (refer to Section 3.1). 3. Remove the upper and lower drive-mounting shelf combination (refer to Section 3.11). 4. Disconnect the power cable from the CPU module (refer to Figure 3-44). 5. Loosen the two captive screws (refer to Figure 3-46). Removing and Replacing Field Replaceable Units 3-73 Removing and Replacing Field Replaceable Units 3.19 Removing the Power Supply Figure 3-46 Removing the Power Supply 6. Loosen the two Phillips screws (90-09984-07) that secure the power supply to the left side of the enclosure (refer to Figure 3-46). ------------------------------------------------------------ Caution ------------------------------------------------------------ Ensure that you do not damage any of the MS44 or MS44L memory modules when you lift the power supply out of the enclosure. ------------------------------------------------------------ 7. Lift the front of the power supply (refer to Figure 3-46). 8. Remove the power supply from the enclosure. 3-74 Removing and Replacing Field Replaceable Units A ------------------------------------------------------------ Pin Specifications for the Ports on the BA42B System Figure A-1 shows the pin specifications for the ports on the BA42B system.
