1.2 Major Units The following subsections describe the major units of the VAX 4000 Model 500 system and their functions. A full description on how to use the system and options can be found in the VAX 4000 Model 500 Operation manual. 1.2.1 Front Assemblies The functions of the front assemblies of the VAX 4000 Model 500 are described in the following sections. 1.2.1.1 Mass Storage Shelf The mass storage shelf (see Figure 1–3) extends across the front of the enclosure.
Figure 1–3: Mass Storage Shelf 1.2.1.2 System Control Panel The SCP is to the left of the storage devices (see Figure 1–3). The SCP has two indicators (see Figure 1–4): the dc ok light and the overtemperature warning light. The green dc ok light indicates that the power supply voltages are within the correct operating range. If the dc ok light is not lit when the system power is on, check the system ON/OFF switch on the front bezel (refer to Section 1.2.1.
breaker on the power supply and the power cord, then refer to the VAX 4000 Troubleshooting and Diagnostics manual. Figure 1–4: System Control Panel The red over-temperature indicator flashes when the internal temperature approaches a level that may cause system components to overheat. An audible alarm also provides a warning of a possible over-temperature condition. If the components continue to heat, the system automatically shuts down to prevent component damage.
on the console terminal screen. Now you can enter console commands. If you inadvertently press the Halt button, type c Return to continue. The VAX 4000 Model 500 Operation manual describes halting the system in more detail. CAUTION Pressing the Halt button halts the system regardless of the setting of the break enable/disable switch on the console bulkhead assembly. Below the Halt button is the Restart/Run button. The Restart/Run button has a green indicator.
Figure 1–5: Console Bulkhead Controls System Overview 1–9
1.2.1.3 System ON/OFF Switch The main system ON/OFF switch is located in the upper left-hand corner of the front panel (see Figure 1–3). This switch is the power switch for the entire system. 1.2.2 Card Cage The modules in your system are mounted in a 12-slot card cage behind the mass storage shelf, as shown in Figure 1–6. The slots are numbered beginning with slot one next to the power supply.
Figure 1–6: Card Cage System Overview 1–11
Figure 1–7: Q–bus Option Slots 1–12 System Overview
CAUTION Do not operate the system without Digital-supplied slot covers. The covers are required to protect the equipment and to meet international regulatory standards. Do not substitute other slot covers, as they may not meet the required specifications. The design of the module covers varies, depending on the type of module installed in the slot. Modules requiring external cable connections such as communications controllers have recessed covers that are riveted directly to the module.
Figure 1–8: Console Bulkhead Assembly Controls, Indicators, and Connectors 1–14 System Overview
The console bulkhead assembly contains the following controls and indicators: Power-Up mode switch — This three-position rotary switch determines how the system responds at power-up: Language inquiry mode (the position indicated by a profile of a face) causes the system to display a language selection menu at power-up if your console terminal supports multiple languages.
Break enable/disable switch — When this switch is pushed back (down or O position), breaks are disabled. When it is forward (up or | position), breaks are enabled. When breaks are enabled, pressing Break on the console terminal halts the processor and transfers control to the console program. Using the console command SET CONTROL, you can specify the control character Ctrl/C rather than Break to initiate a break signal. The break enable/disable switch also controls what happens at power-on.
back position. A green indicator light (LED) for each connector indicates which connector is active. 1.2.3 DSSI and SCSI Connectors (DSSI Bus 0; SCSI Bus 0) To the right of the card cage are the DSSI and SCSI (KZQSA In) connectors (see Figure 1–9) for their respective Bus 0. Bus 0 provides the DSSI and SCSI bus for ISEs installed in the system enclosure. The connectors allow you to expand your system by connecting additional mass storage devices to the bus.
Figure 1–9: Connectors for DSSI Bus 0 and SCSI Bus 0 1–18 System Overview
1.2.4 Power Supply Controls and Indicators To the left of the card cage is the power supply (see Figure 1–10) which provides power to the mass storage devices, the modules installed in the card cage, and the fans. To prevent damage from overheating, the power supply monitors the internal temperature and the speed of the fans. If the power supply detects overheating or a fan failure, the power supply shuts down the system. Figure 1–10 shows the controls, indicators, and connectors on the power supply.
Figure 1–10: Power Supply Controls and Indicators 1–20 System Overview
The controls, indicators, and connectors function as follows: Power supply circuit breaker — This switch is used to turn the power supply on and off. The OFF position is indicated by a O; the ON position is indicated by a | . NOTE To operate the VAX 4000 Model 500, the power supply circuit breaker must be in the ON ( | ) position. A power surge will cause the breaker to trip and set the system ON/OFF switch to the OFF position (O).
Power bus connectors — There are three power bus connectors (MO, SO, and SI). The main-out (MO) connector is the source for the power control bus signal to the expander. One end of a power-bus cable is connected here and the other end is connected to the power supply secondary-in (SI) connector of an R400X expander. In the VAX 4000 Model 500, the secondary-in (SI) connector receives the power bus control signal from the front panel system ON/OFF switch.
1.2.5 Fans Two fans, located behind the card cage, draw air in through the front of the VAX 4000 chassis, through the card cage, and out the rear of the VAX 4000. The speed of the fans varies, depending on the ambient room temperature. To reduce the load on the fans, keep the system away from heat sources. Figure 1–11 shows the airflow through the VAX 4000 system enclosure. NOTE The power supply monitors the fans.
