Chapter 1 BA430/BA440 Enclosure Description 1.1 Introduction The BA430/BA440 pedestal enclosure shown in Figure 1–1 is used in a free standing pedestal for use in an office environment.
Figure 1–1: BA430/BA440 Pedestal Enclosure MLO-004032 1.2 Enclosure Keylock Access To gain access to the BA430/BA440 enclosure, there is a three-position lock that determines which controls you can access (Figure 1–2). The level of access is as follows: 1. Top position opens the upper door only. 2. Middle position locks both doors. 3. Bottom position opens both doors together.
Figure 1–2: Keylock Positions Top Key Position MLO-004034 Bottom Key Position MLO-004035 MLO-004207 1.3 Module Handles and Covers The BA400-series and the BA200-series enclosures provide front access to the CPU and memory and option modules, making it easier to access them.
and internal cabling found in other enclosures. This design is easier to maintain since it eliminates problems caused by faulty internal cabling. • Modules that do not have external I/O connections have blank bulkhead covers.
Figure 1–3: BA400-series Module Handles and Covers Captive Screw Filler Panel Single-Width Blank Cover Double-Width Single-Width Blank Cover Flush Cover with Handles Single-Width Recessed Cover with Handles Stiffner with Ratchet Handles MLO-005413 Some modules have special configurations, such as the BA440’s H3604 console module, which is a hinged module cover that covers the CPU and four memory modules. The H3604 console module also provides an I/O connector for the CPU.
Table 1–1: BA400-Series Module Handles and Cover Types Part Description Single-width blank cover Covers a standard Q22-bus module that does not have external I/O connectors (for example, a TQK70). If you install this type of cover next to a module with a recessed handle, you must add a metal filler panel to maintain FCC compliance. Single-width ratchet ejector handle The CPU module is equipped with ratchet ejector handles to keep the right amount of tension against the backplane connector.

See Figure 1–11.
The temperature warning indicator shows that the system’s internal temperature is approaching a level that may cause system components to overheat. If the internal temperature raises unacceptably, you will hear an audible pulsing sound and the temperature warning indicator will flash. The sound and visual marker are warning you of a possible temperature condition, before the system automatically shuts down. This feature allows you time to take corrective action.
1.9.1 Halt and Restart Switch Disable There are four switches located on the top of the system control panel. These switches, when positioned off, disable the Halt and Restart button functions on the SCP. This could be used as a safety feature. When the upper door is open, these switches protect the system from accidentally being halted or restarted. Figure 1–11 shows the location of the switch pack, which allows the disabling of the SCP buttons.

Chapter 2 Installation This chapter contains the procedure for installing the BA430/BA440 pedestal enclosure. 2.1 Site Preparation Considerations 2.1.1 BA430/BA440 Physical Dimensions Figure 2–1 shows the dimensions of the BA430/BA440 enclosure. You must leave at least 61 cm (24 in) of clearance in front of the system to access the doors and the system controls. You must also leave at least 5 cm (2 in) of clearance at the sides and rear for airflow.
Figure 2–1: BA430/BA440 Enclosure Dimensions 69 cm (27 in) 45 cm (17.88 in) 53 cm (21 in) WEIGHT: 49.9 kg to 68 kg (110 lb to 150 lb) MLO-004190 2.1.2 Additional Equipment Make sure there is enough space for terminals and other peripheral equipment. When you plan the cable routing for multiterminal systems, consider factors such as safety, convenience, future expansion, and cost. Cabling should be in place and labeled after you install the system. 2.1.
• Provide as many electrical outlets as are required for each additional device, such as any table top device and console terminal. 2.1.4 Acoustics The BA430/BA440 pedestal is designed for use in offices and other general working areas. The following acoustic emission and heat dissipation levels are for the BA430/BA440 pedestal. Levels may be lower, depending on the kind and number of mass storage devices in the system. Data is measured in accordance with ANSI S12.
2.1.7 Electrical Requirements The power source should be adequate to handle the original system and allow for system expansion. Digital recommends a dedicated circuit from the power source to each system. Additional power equipment may be required to avoid power disturbances. Table 2–2 lists the electrical requirements for systems in a BA430/BA440 pedestal. Table 2–3 lists the power cords required.
2.2 Unpacking the Shipment The shipment may include several cartons: • One contains the system unit. • One contains cables for connecting additional devices to the system. • Several contain components of the console terminal. • Another, marked software, contains software documentation, system software, diagnostic software, and a software license. NOTE: Save all packing materials if you plan to reship the system.
Figure 2–2: Sliding the System into Place Hand Holds Slides Front to Back Rolls Left to Right MLO-004012 During installation, leave a few inches behind the system for routing cables underneath the system unit.
