System Overview

1.1 Introduction

This chapter presents an overview of the Rack-Mountable VAX 4000

Model 500 computer system.

The Rack-Mountable VAX 4000 Model 500 computer system (see Figure 1–1) houses all components in a BA441 enclosure. Figure 1–2 shows the dimensions of the enclosure. This enclosure is a slide mounted chassis that fits into a standard 48.26-cm (19-inch) EIA enclosure and houses the following major units:

• Front Assemblies

— Mass storage shelf

— System control panel (SCP)

— System ON/OFF switch

• Card cage

— DSSI and Small Computer System Interface (SCSI) connectors

— Console bulkhead assembly

— Central processing unit (CPU) module

— Memory modules

System Overview 1–1

• Power supply

• Fans

Your BA441 enclosure containing the Rack-Mountable VAX 4000 Model

500 computer system can also contain the following options:

• Communications controller modules

• RF-series integrated storage equipment (ISE)

• Tape drive controller module

• TK50, TK70, or TF85 tape drive

Up to four RF-series ISEs or up to three RF-series ISEs and a tape drive can be mounted inside the BA441 enclosure.

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. The shelf can contain an optional TK50, TK70 or TF85 tape drive with up to three RF-series ISEs. Tapeless systems can have up to four RF-series ISEs. Each ISE has its own panel with controls and indicators. Instructions for using ISEs and the tape drive can be found in the VAX 4000 Model 500 Operation manual.

System Overview 1–5

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 1.2.1.3), the circuit

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. Instructions for turning on the system after a preventive shutdown due to overheat conditions are covered in the VAX 4000 Model 500 Operation manual.

Below the indicators are the Halt and Restart/Run buttons. The Halt button is a two-position button. When you press the button, the system halts. A red indicator on the Halt button lights when the button is set to the in position. Before you can enter console commands, press the Halt button again to return it to the out position. When the Halt button is returned to the out position, the console mode prompt >>> is displayed

System Overview 1–7

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. When you press the Restart/Run button, the system returns to a power-on condition and self-tests are run. If you have a boot device and if the | /O (break/enable disable) switch (see

Figure 1–5) is set to O (disable), the system will reboot system software.

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.

A console bulkhead assembly with indicators, system controls, and connectors covers the memory modules and CPU in the first five slots.

1.2.2.1 Memory Modules

The first four slots are reserved for memory modules.

1.2.2.2 CPU

The CPU is in the fifth slot.

1.2.2.3 Q–bus Option Modules

Slots 6 through 12 are available for Q–bus option modules (see Figure 1–7). The number and type of modules installed in your system depend on your configuration. Each Q–bus slot, even an empty one, is protected by a cover. Together these covers and the console bulkhead assembly form a shield with a three-fold purpose:

1.

To protect external devices from electrical interference generated by the system, maintaining compliance with FCC and VDE requirements.

2.

To protect the system from electrical interference generated by external devices.

3.

To maintain airflow integrity.

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.

The recessed module covers allow space for connecting cables. Modules requiring no external cable connections such as mass storage controllers are covered by flush covers. Empty slots are also covered by flush covers, which may be single or double width. All covers, except those covering empty slots, have a label identifying the module installed in the slot.

Cables connecting your system to peripheral devices (such as terminals, modems, and printers) are attached to communications controllers. Each cable can contain multiple lines. The cables run over the top of the BA441 enclosure and towards the back, where the cables are split into individual lines. These connections are described in more detail in the VAX 4000

Model 500 Operation manual.

1.2.2.4 Console Bulkhead Assembly

The console bulkhead assembly (see Figure 1–8) covers slots 1 through

5, and has several system controls, indicators and connectors.

NOTE

The console bulkhead assembly is visible when the chassis is extended and viewed from the top (see Figure 1–8).

System Overview 1–13

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. Also, if a default boot device has not been selected, this mode causes the system to issue a list of bootable devices and prompts you to select a device from the list. Once a device is selected, the system autoboots from that device each time you turn it on.

Run mode (the position indicated by an arrow) is the normal operating setting.

Loop back test mode (the position indicated by a T in a circle) causes the system to run loopback tests on the console serial line at power-on. This setting requires special loopback connectors and is for Digital Customer

Services use only.

Baud rate select switch — This switch sets the system baud rate to match that of the console terminal. The factory setting is position 5 (9600).

Modified modular jack (MMJ) — This console terminal connector provides the connection for the console terminal.

Light-emitting diode (LED) — This display shows the testing sequence during power-up.

System Overview 1–15

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. When breaks are disabled (down or O position), the system attempts to automatically boot software at power-on.

When breaks are enabled (up or | position), the system enters console mode (indicated by the >>> prompt) at power-on.

Using the console command SET HALT REBOOT or SET

HALT RESTART_REBOOT, you can set your system to automatically boot software after the system is halted by pressing

Break

.

Bus node ID plugs — VAX 4000 systems have two separate

DSSI buses. Two DSSI bus node ID plugs, one for the internal

DSSI bus (Bus 0) and one for the external bus (Bus 1), identify the bus node to the CPU. These plugs are configured at the factory. For single-host systems, Bus 0 is identified as Bus

Node 6, Bus 1 is identified as Bus Node 7.

DSSI connectors (DSSI Bus 1) — These two DSSI connectors, labeled X and Y on the console bulkhead assembly, allow you to expand your system by connecting additional mass storage devices to the second DSSI bus.

Ethernet connectors — The console bulkhead assembly has two Ethernet connectors: a BNC-type connector for ThinWire

Ethernet, and a 15-pin connector for a standard Ethernet transceiver cable.

Ethernet connector switch — This switch selects either the

ThinWire or the standard Ethernet connection. To use the standard connection, set the switch to the forward position.

To use the ThinWire cable connection, set the switch to the

1–16 System Overview

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.

System Overview 1–17

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.

NOTE

These controls, indicators, and connectors are visible when the chassis is extended and viewed from the top

(see Figure 1–10).

System Overview 1–19

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). Setting the system ON

/OFF switch to ON ( | ) resets the power supply circuit breaker.

If the circuit breaker trips, wait one minute before setting the system ON/OFF switch to ON.

AC present indicator — This indicator lights when the system

ON/OFF switch and power supply circuit breaker are set to

ON and voltage is present at the input of the power supply.

If the ac present indicator does not light when the ON/OFF switch and power supply circuit breaker are set to ON, refer to the VAX 4000 Troubleshooting and Diagnostics manual.

DC OK indicator — This indicator lights when the power supply voltages are within the correct operating range. If the dc ok indicator does not light when the power switches are set to ON, refer to your VAX 4000 Troubleshooting and Diagnostics manual.

Fan failure indicator — This indicator lights if either of the two cooling fans stop working. The power supply automatically shuts down the system as a precautionary measure when a fan failure is detected. Call your Digital service representative if a fan failure occurs.

Over-temperature condition indicator — This amber overtemperature condition indicator lights if the enclosure has shut down due to an over-temperature condition.

System Overview 1–21

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. In a power bus with more than one expander, the power control bus signal is connected between expanders using the secondary in and out connectors (see Section 2.7.4)

NOTE

The SI connector is not available for system expansion.

The secondary-out (SO) connector is not used on the

VAX 4000 system. It is used to send the signal down the power bus for configurations with more than one expander.

1–22 System Overview

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. If either fan stops working, the fan failure indicator on the power supply lights, and the system automatically shuts down as a precautionary measure. Call your Digital service representative if a fan fails.

The fan speed control can be set so that the fans will run at their maximum speed. This setting is recommended if you want potentially higher system module reliability, and do not object to the increased fan noise. Contact your Digital service representative to override the fan speed control.

While optional, Digital strongly recommends that you run the diagnostic software before you install system software or start factory-installed

VMS software for the first time. The diagnostics verify the system’s configuration and check to see if each device is working properly. The diagnostic software is on a tape cartridge labeled MV DIAG CUST TK50.

The VAX 4000 Troubleshooting and Diagnostics manual describes how to run the diagnostic software.

If you have VMS FIS (factory installed software) on your system, refer to the VMS Factory Installed Software User Guide for the startup procedure. Otherwise, install the system software that comes with your system.

NOTE

Systems that come with FIS have a yellow sticker on the front panel of the ISE containing the FIS.
