The hardware and software for each of these systems differ slightly, according to the function of the system. The VAX 4000 is a multiuser system that uses the VMS operating system. The VAXserver 4000 system is a single-user system that uses VMS or VAXELN operating systems. Both systems can function as an end- or full-function node on an Ethernet network.

The manual is structured as follows:

• Chapter 1 provides an overview of the systems.

• Chapter 2 describes how to use each system.

• Chapter 3 describes how to use options installed in the systems.

• Appendix A lists related documentation.

• Appendix B describes how to set and examine DSSI device parameters

from console mode.

• Appendix C describes procedures for creating backup ﬁles.

• Appendix D describes how to use VMSTAILOR to remove unwanted

VMS ﬁles from the system disk.

• The glossary explains key terms.

NOTE: VAXserver systems offer maximumperformance for applications that do not require timesharing. Some devices in this manual are for multiuser systems and may not be suitable for server systems. Contact your Digital service representative if you have any questions about whether use of a speciﬁc device is appropriate for your server system.

System Control Panel (SCP)

MLO-005386

The SCP has two indicators: the Over Temperature Warning indicator and the DC OK indicator. The red Over Temperature Warning indicator ﬂashes to indicate that the system’s internal temperature is approaching a level that may cause system components to overheat. In addition to the ﬂashing Over Temperature Warning indicator, an audible alarm also provides warning of a possible over temperature condition. If the components continue to heat, the system will automatically shut down to prevent components from being damaged. Chapter 2 provides instruction for turning on the system after a preventive shutdown due to overheat conditions.

The green DC OK indicator shows that the power supply voltages are within the correct operating range. If the DC OK indicator is not lit when the system power is on, refer to the VAX 4000 Model 200 Troubleshooting and Diagnostics manual included in the Customer Hardware Information Kit.

Below the indicators are the Halt and Restart 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

1–8 VAX 4000 Model 200 (BA430) Operation

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 on the console terminal screen. Now you can enter console commands. If you inadvertently press the Halt button, enter c

Return

to continue. Chapter 2

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 CPU cover panel.

Below the Halt button is the Restart button. The Restart button has a green indicator. When you press the Restart button, the system returns to a power-up condition and self-tests are run. If you have speciﬁed a device as the boot device and if the Break Enable/Disable switch is set to disable, the system will reboot system software. Further instructions on restarting your system are in Chapter 2.

NOTE: The Halt and Restart buttons can be disabled to prevent accidental activation. Contact your Digital service representative if you want to disable the controls on the SCP.

System Overview 1–9

1.1.1.2 Card Cage

The modules in your system are mounted in a 12-slot card cage under the mass storage shelf, as shown in Figure 1–7.

Figure 1–7: Card Cage

Slots 12 - 1

MLO-005503

The ﬁrst slot is reserved for the central processing unit (CPU). Up to four MS650 memory modules may follow the CPU. The CPU and the ﬁrst memory module (slots 1 and 2) are covered by a dual-width CPU cover panel with system controls and connectors. The remaining slots are available for Q-bus option modules.

1–10 VAX 4000 Model 200 (BA430) Operation

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 module cover. The purpose of the shield is as follows:

• To protect external devices from electrical interference generated by the

system

• To protect the system from electrical interference generated by external

devices

• To maintain air ﬂow integrity

CAUTION: Do not operate the system without Digital-supplied module covers. The covers are required to protect the equipment and to meet international regulatory standards. Do not substitute other module covers, as they may not meet the required speciﬁcations.

Operating the system without the module covers has the following consequences:

• The system may overheat due to improper air circulation.

• The system will not comply with FCC and VDE requirements for

electrostatic shielding and may produce electrical interference that affects other equipment.

• The system is susceptible to electrical interference or damage from

external sources.

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 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 under the BA430 enclosure and out the back or side of the enclosure, where the cables are split into individual lines. Chapter 3 describes these connections in more detail.

System Overview 1–11

1.1.1.3 CPU Cover Panel

The CPU module and the ﬁrst memory module are behind a double-width cover panel that has internal cable connections to the memory module(s). Figure 1–8 shows the CPU cover panel.

1–12 VAX 4000 Model 200 (BA430) Operation

The CPU cover panel has the following components:

Power-Up Mode switch—This three-position rotary switch determines how the system responds at power-up:

Language Inquiry Mode (in the top 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 (in the middle position, indicated by an arrow) is the normal operating setting.

Loop Back Test Mode (in the bottom position, indicated by a T in a circle) causes the system to run loopback tests on the console serial line at power-up. This setting requires special loopback connectors and is for Digital Customer Services use only.

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

The light-emitting diode (LED) display shows the testing sequence during power-up.

Break Enable/Disable switch—When the switch is down (dot outside the circle), breaks are disabled. When the switch is up (dot inside the circle), 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 CONTROLP, you can specify the control character,

Ctrl/P

, rather than

Break

to initiate a break signal.

System Overview 1–13

The Break Enable/Disable switch also controls what happens at power-up. When breaks are disabled (down, dot outside the circle), the system attempts to automatically boot software at power-up. When breaks are enabled (up, dot inside the circle), the system enters console mode (indicated by the (>>>) prompt) at power-up.

Using the console commands, SET HALT REBOOT and SET HALT RESTART_REBOOT, you can set your system to override the Break Enable/Disable switch and automatically boot software after an error halt condition or power-up, even if breaks are enabled.

Ethernet connectors—The CPU cover panel has two Ethernet connectors: a BNC-type connector for ThinWire Ethernet and a 15-pin connector for a standard Ethernet transceiver cable. The Ethernet connector switch allows you to set the type of connection. To use the standard transceiver cable connection, set the switch to the up position. To use the ThinWire cable connection, set the switch to the down position. A green indicator light (LED) for each connector indicates which connection is active.

1.1.1.4 DSSI and KZQSA Connectors

To the left of the card cage is a panel that provides two connectors: a DSSI connector and a KZQSA In connector. The DSSI connector allows you to expand your system with additional RF-series ISEs by connecting a system expansion enclosure to the bus. You can also share ISEs with a second system by forming a dual-host conﬁguration.

The KZQSA In connector is for those systems using a built-in TLZ04 tape drive. A 2.5-ft cable (BC06P–2F) links the TLZ04 tape drive and its KZQSA controller through the KZQSA In connector. Figure 1–9 shows the location of the DSSI and KZQSA In connectors.

1.1.1.5 Power Supply Controls and Indicators

To the right of the card cage is the power supply. Thepower supply provides power to the mass storage devices, the modules installed in the card cage, and the fans.

To prevent damage due to 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 will shut down the system.

The controls and indicators function as follows:

Power switch—The Power switch is used to turn system power on and off. The off position is indicated by a 0; the on position is indicated by a 1.

The Power switch also functions as the system circuit breaker. In the event of a power surge, the breaker will trip, causing the Power switch to return to the off position (0). Turning the system on resets the circuit breaker. If the circuit breaker trips, wait one minute before turning the system back on.

AC Present Indicator—The orange AC Present indicator lights when the Power switch is set to on and voltage is present at the input of the power supply. If the AC Present indicator does not light when the Power switch is set to on, refer to your VAX 4000 Model 200 Troubleshooting and Diagnostics manual.

DC OK—When the green DC OK indicator is lit, the power supply voltages are within the correct operating range. If the DC OK indicator does not light when the Power switch is set to on, refer to your VAX 4000 Model 200 Troubleshooting and Diagnostics manual.

Fan Failure indicator—The amber Fan Failure indicator lights if either of the two cooling fans stops working. The power supply will automatically shut 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—The amber Over Temperature Condition indicator lights if the enclosure has shut down due to an over temperature condition. Section 2.9 provides instructions on recovering from an over temperature condition.

Power bus connectors—Three power bus connectors allow you to conﬁgure a power bus for systems expanded with the R400X or B400X expander. The power bus allows you to turn power on and off for one or more expanders through the power supply designated as the main power supply: this way, one power switch can control power for an entire expanded system. Figure 1–11 illustrates a possible power bus conﬁguration for an expanded system.

NOTE: Dual-host systems should not be conﬁgured with a power bus. Inadvertently shutting off a host system and bringing down the cluster defeats the added reliability of a dual-host system.

The main out (MO) connector sends the power control bus signal to the expander. One end of a power bus cable is connected here, the other end is connected to the secondary in (SI) connector of an expander power supply.

The secondary in (SI) connector receives the power bus control signal from the main power supply. In a power

System Overview 1–17

bus with more than one expander, the power control bus signal is passed along, using the secondary in and out connectors as shown in Figure 1–11.

The secondary out (SO) connector sends the signal down the power bus for conﬁgurations of more than one expander.

1.1.1.6 Fans

Two fans located under the card cage draw air in through the top of the enclosure, down through the card cage, and out the bottom. The speed of the fans varies, depending on the surrounding room temperature. Toreduce the load on the fans, keep the system away from heat sources. Figure 1–12 shows the air ﬂow through the 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.

1–18 VAX 4000 Model 200 (BA430) Operation

NOTE: 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.

1.2 Functional Description of Base System

Each VAX 4000 system includes base system components common to all systems. Your system may have optional components as well. Your system was conﬁgured at the factory, based on your order.

The following sections describe base system components and options.

1.2.1 Base System Components

Base system components include the following:

• Central processing unit (CPU)

• Console serial line unit (SLU)

• Main memory

System Overview 1–19

• Network controller

• Embedded DSSI host adapter

1.2.1.1 Central Processing Unit (CPU)

The central processing unit (CPU) controls the execution of all instructions and processes. The CPU circuits contain the logic, arithmetic, and control functions used by the system.

1.2.1.2 Console Serial Line Unit (SLU)

Each system has a serial line unit connecting the console terminal to the system. The SLU connector (a modiﬁed modular jack) is located on the CPU cover panel. The console serial line provides a means of communicating with the CPU.

1.2.1.3 Main Memory

Main memory provides the electrical storage area for data and instructions used by the CPU. When you start your system, the operating system is loaded into main memory. Application programs must also be loaded into memory.

When the system cannot load everything into memory at once, it reads in units of data called pages (512 bytes of data) from disk. A large main memory increases the efﬁciency of processing, since fewer pages must be copied to and from the disk. Each conﬁguration comes with a standard memory option. There is room for up to four memory modules. By adding more main memory, you can increase efﬁciency.

The contents of memory are volatile. This means they are lost when you turn off power to the system. Use mass storage devices, such as integrated storage elements and tape cartridges, to store softwareand data permanently.

1.2.1.4 Network Controller

Network communications controllers allow you to connect to an Ethernet network. With a network connection and appropriate DECnet software, you can use network services, such as mail; access data stored on other systems; perform operations, such as editing and printing on remote systems; and share resources, such as laser printers. Your system comes with an onboard Ethernet controller that is part of the CPU module. The system can connect to an Ethernet network through either standard Ethernet cable or ThinWire Ethernet cable. Connectors for both types of cables are on the CPU cover panel.

1–20 VAX 4000 Model 200 (BA430) Operation

1.2.1.5 Embedded DSSI Host Adapter

Your system has a Digital Storage Systems Interconnect (DSSI) adapter built into the CPU module. The DSSI adapter provides a path to the DSSI bus through which the CPU communicates with DSSI devices. A DSSI adapter can support seven DSSI devices.

The DSSI host adapter also allows you to link the DSSI bus to a second host to form a dual-host conﬁguration. When a DSSI bus is extended to a second system, both systems can share up to six DSSI devices. Refer to Section 1.3 for further discussion of DSSI VAXcluster or dual-host systems.

1.2.2 Optional Components

System options can include multiples of components that are part of the base system (for example, additional memory modules or ISEs) and the following kinds of options:

• Mass storage devices and controllers

• Mass storage subsystems

• Mass storage expanders

• Communications controllers and adapters

• Real-time controllers

• Printer interfaces

1.2.2.1 Mass Storage Devices and Controllers

Mass storage devices record data on magnetic media. The data recorded is not lost when you turn off the system, but can be altered or erased if you record over the data. Use mass storage devices to store data and software permanently. When the data or software is needed, the CPU transfers it from the mass storage device into main memory. The two primary types of mass storage devices are the RF-series ISEs and devices with removable media, such as tape cartridges and compact discs.

Integrated Storage Elements

Up to four RF-series ISEs can be installed in your system. An ISE is an intelligent storage device that contains its own controller and Mass Storage Control Protocol (MSCP) server. Special mounting hardware allows the device to plug directly into the BA400-series backplane.

Devices with Removable Media

Devices with removable media, such as tape cartridges, are used as both input and output devices. In addition, compact optical disks are used as

System Overview 1–21

input devices when you install software or copy data to your system. You use tape cartridges and tapes as output devices when you copy software or data from your system. You can copy individual ﬁles or programs or you can copy (back up) the contents of an entire ﬁxed disk. Tapes are commonly used to archive data.

Mass Storage Controllers and Adapters

All mass storage devices require a controller, a device that controls activity between the CPU and the mass storage devices. While the controller for a DSSI device is built into the storage element, other storage options require a controller module located in your system’s card cage. The controller for the TK70 tape drive is the TQK70; the KDA50 is a controller for RA-series disk drives. Each KDA50 controller supports up to four RA-series disk drives.

The KZQSA adapter allows the CPU to communicate with the TLZ04 tape drive or an RRD40-series compact disc drive. Each KZQSA adapter can support up to two drives.

The CPU communicates with the ISEs through a Digital Storage Systems Interconnect (DSSI) adapter, which is built into the CPU. A DSSI bus is capable of supporting seven DSSI devices. A second and third DSSI bus can be added to your system by using up to two KFQSA DSSI storage adapter modules. Each KFQSA storage adapter can support up to seven RF-series ISEs.

NOTE: As of this printing, the KFQSA storage adapter does not yet support the TF85 tape drive.

1.2.2.2 Mass Storage Subsystems

Several optional mass storage subsystems are available for VAX 4000 systems. Such subsystems include RRD40-series Compact Disc Drive Subsystems, the RV20 Optical Disk Subsystem, TSZ07, TSV05, and TU81E tape drives, and the SA600 Storage Array (with up to eight RA90 disk drives). If your system includes an optional mass storage subsystem, refer to the user’s guide or owner’s manual for that subsystem for instructions on how to operate the device.

1.2.2.3 Mass Storage Expanders

You can expand the mass storage and Q-bus capacity of your VAX 4000 system by using the following:

• The R400X mass storage expander provides space for up to seven additional RF-series ISEs or up to six RF-series ISEs and a tape drive (TF85 or TLZ04).

1–22 VAX 4000 Model 200 (BA430) Operation

• The R215F expander provides space for up to three RF-series ISEs.

• The B400X expander provides 10 additional Q-bus slots for a system total of 22 Q-bus slots. The B400X also has space for up to four additional RF-series ISEs or up to three ISEs and a tape drive (TF85, TK70, or TLZ04).

• The B213F expander also provides 10 additional Q-bus slots and provides space for up to four RF-series ISEs or up to three ISEs and a TK70 tape drive.

Contact your Digital representative for more information on these and other expander products.

1.2.2.4 Communications Controllers

Besides the console serial line, most systems have additional communications controllers for connecting additional terminals, and for communicating with other systems over telephone or network lines. Communications controllers provide standard interfaces between peripheral devices and the system. Many communications controllers provide support for multiple data lines.

The following types of communications controllers are available:

• Asynchronous serial controllers

• Synchronous serial controllers

• DECservers

• Network controllers

Serial controllers transmit data one character at a time. A device at the transmitting end breaks bytes of data into bits. A device at the receiving end assembles incoming bits into bytes of data.

Asynchronous Serial Controllers

Asynchronous serial controllers provide low-speed connections between peripheral devices and the system. Asynchronous communication between the system and the peripheral depends on recognition of a pattern of start and stop bits, not on a time interval.

Asynchronous serial controllers may be divided into those without modem support and those with modem support.

You use serial controllers without modem support to connect additional terminals and printers to your system. For example, the CXA16 module provides connections for up to 16 serial lines with no modem support.

System Overview 1–23

NOTE: Printers equipped with a microprocessor (intelligent printers) may require modem control signals to function correctly. Do not attach a printer requiring modem control signals to a controller with no modem support. Check your printer documentation to determine the proper communications interface for your printer.

Communications controllers with modem support allow you to communicate over telephone lines. With a modem connected to your system, you can access other computers and you can dial into your system from a remote terminal or computer.

Computers transmit digital signals, while telephone lines (with the exception of digital leased lines) transmit analog signals. When two computers communicate over telephone lines, a modem is required at both the transmitting and receiving ends of the line. At thetransmitting end, the modem converts digital signals from the computer (or terminal) to analog signals before transmission. At the receiving end, another modem converts the analog signals back into digital signals the computer can process.

The degree of modem support depends on the number of modem control signals recognized by the device. Full modem support (according to Digital standards) requires recognition of 11 signals. The CXY08 module supports up to 8 serial lines with full modem support.

Synchronous Serial Controllers

Synchronous serial controllers provide high-speed connections between systems. Communication between synchronous devices depends on time intervals that are synchronized before transmission of data begins. Synchronous devices can also have modem support.

DECservers

DECservers are terminal servers (a combination of hardware and software) that allow you to connect multiple terminals or printers to hosts in an Ethernet Local Area Network (LAN).

Terminal servers perform the functions of traditional data terminal switches but multiplex the lines over the Ethernet. Using a DECserver ofﬂoads communications processing from the host system.

Network Controllers

Network communications controllers allow you to connect to an Ethernet LAN or other network type. With a network connection and appropriate DECnet software, you can use network services, such as mail; access data stored on other systems; perform operations, suchas editing and printing on remote systems; and share resources, such as laser printers. The network

1–24 VAX 4000 Model 200 (BA430) Operation

controller function for your system is implemented on theCPU module, but a second network controller, the DESQA Ethernet adapter module, can be added to your system.

1.2.2.5 Real-Time Controllers

Real-time controllers interface with devices that monitor or control particular processes; for example, laboratory equipment or manufacturing equipment connected to the system. Typically, real-time controllers are parallel devices, not serial devices.

1.2.2.6 Printer Interfaces

Some printers require speciﬁc interfaces to communicate with the system. For example, the LG01, LG02, and LP29 and LP37 printers require the LPV11–SA interface module.

1.2.2.7 Other Available Options

Your system arrives conﬁgured with the options you ordered. As your needs change, you can add more options. Your Digital sales representative can advise you on available options. VAX 4000 Model 200 Technical Information describes the options currently available for VAX 4000 systems. Digital provides installation for additional options that you order.

1.3 Dual-Host Capability (VMS Systems Only)

A dual-host system consists of two systems in a VAXcluster sharing their ISEs through a Digital Storage Systems Interconnect (DSSI) bus. Each system can have direct access to any of the ISEs in either system; this can include a shared common system disk.

The primary application for such a conﬁguration is a VAXcluster system. The simplest dual-host conﬁguration, for example, is to conﬁgure one system disk to be used as the system disk by both systems. The system disk physically resides in one enclosure; however, both systems have equal access to the system disk and to any other DSSI mass storage device in either enclosure over a common DSSI bus.

A DSSI device, such as the RF72, has a built-in dual-host capability that allows it to connect to two DSSI host adapters. The DSSI storage adapter, embedded in the system’s CPU, allows you to extend a DSSI bus by physically connecting it to another system.

Using an external DSSI cable, any two DSSI-based systems can be connected to form a dual-host conﬁguration. Figure 1–13 shows a dualhost conﬁguration with two VAX 4000 systems.

System Overview 1–25

NOTE: Dual-host capability for VAX 4000 Model 200 systems is only supported under VMS (Version 5.4 and later) when the two systems are conﬁgured into the same VAXcluster.

The beneﬁts of a dual-host conﬁguration are:

• VAXcluster features such as shared data across systems and satellite nodes.

• Higher system availability—If one of the DSSI-based systems is unavailable, for example, due to a system malfunction, the satellites booted through it are able to continue operating through the other system.

If one of the DSSI-based systems fails, all satellite nodes booted through that system lose connections to the system disk. Each satellite node knows, however, that the system disk is also available through a second path. The satellite nodes establish a new connection through the other system and continue operation.

To increase system availability, a second system disk may be added to each boot node. In the event of one system disk failure, the remaining system disk would continue to serve one DSSI-based system and the satellite nodes booted through it. As with any VAXcluster, however, a second system disk improves availability while increasing system management tasks.

Chapter 2

Operating the System

This chapter describes how to operate your VAX 4000 (BA430) system once the system software has been installed or you have completed startup procedures for factory-installed VMS.

2.1 Before You Operate the System

This chapter assumes that your system has been properly installed. Installation includes running the diagnostic software and installing the base operating system, or completing the ﬁrst time startup procedures for factory-installed VMS. Refer to Appendix A of the VAX 4000 Model 200 (BA430) Installation manual for instructions on starting up factoryinstalled VMS. To install other operating system options or layered products, see the instructions in your system software installation manual or layered product installation manual. Some of the instructions may require you to open the front door of the system to change switch settings on the CPU cover panel.

The remainder of this chapter assumes that system software has been installed and ﬁrst time startup procedures for factory-installed VMS have been completed.

2.2 Switch Settings

Switch settings vary, depending on the operation being performed. The next two sections describe switch settings for normal and for special operations. Set the switches according to your needs.

2.2.1 Normal Operation

Switch settings for normal operation are the following:

• The Break Enable/Disable switch on the CPU cover panel is set to disable (down, dot outside the circle). Digital recommends you run the system with breaks disabled to prevent the user from inadvertently halting the system by pressing the system causes all activity to stop.

, to initiate a break signal.

• The Power-Up Mode switch on the CPU cover panel is set to Run (indicated by an arrow).

• The baud rate switch inside the CPU cover panel is set to 9600 (factory setting).

• The Write-Protect button for each RF-series ISE is set to out (not lit). This setting allows system software to write to the storage element.

• The Run/Ready button for each RF-series ISE is set to in (glows green when the storage element is not being used). This setting makes the storage element available for use (on-line).

• The Halt button on the SCP is set to out (not lit).

• For expanded systems using power bus cables to link the R400X or B400X expander, the power switches on all expander power supplies should remain on (set to 1) at all times. The system power supply sends the power bus signal needed to turn the expanders on or off.

2.2.2 Special Operation

Certain operations require that you change some of the normal operating settings.

• If you need the ability to halt the system from the console terminal, for example, when installing system software or performing certain types of backup, set the Break Enable/Disable switch to enable (up, dot inside the circle). This allows you to halt the system by pressing console terminal.

NOTE: You can use the console command SET CONTROLP to specify the control character,

Ctrl/P

, rather than

Break

, to initiate a break signal.

Using the console commands, SET HALT REBOOT and SET HALT RESTART_REBOOT, you can set your system to override the Break

Enable/Disable switch and automatically boot software after an error halt condition or power-up, even if breaks are enabled.

• If you want data on a particular ISE to be write protected, you must set the Write-Protect switch to in (glows).

NOTE: ISEs containing system software and user accounts must remain write enabled. ISEs containing applications or sensitive data may be write protected.

• If you want to use the Language Selection Menu to select a new language for the console program, before you turn on your system, set the Power-Up Mode switch to Language Inquiry Mode. A human proﬁle indicates the Language Inquiry Mode. When you turn on your system, a Language Selection Menu appears, as shown in Figure 2–1.

Select a language by typing in the number listed next to the language. Save the language you have selected by rotating the Power-Up Mode switch to Run Mode, indicated by an arrow.

NOTE: If you do not select a language within 30 seconds, the system defaults to English (United States/Canada).

Operating the System 2–3

If the Power-Up Mode switch is set to Run Mode (indicated by an arrow), then the language selected is saved and is automatically used during subsequent reboots of the system.

NOTE: If the Power-Up Mode switch is set to Language Inquiry Mode (indicated by the human proﬁle), the system prompts for the language at each power-up.

In addition to the Language Selection Menu, the system may issue a list of bootable devices and prompt you to select a device from the list. If this happens, refer to Section 2.4.1 for more information.

If your system has been powered off for more than 10 days, the battery unit that saves the system clock and the language selection may have run down. The Language Selection Menu will be automatically displayed when you power on your system, regardless of the Power-Up Mode switch setting. Once the system is booted, reset the system clock as described in your system software manual.

2.3 Turning On the System

Once you have set the switches correctly, you are ready to turn on the system. Use the following procedure:

1. Turn on the console terminal and wait for it to complete its self-tests.

2. Turn on the system by setting the Power switch to 1.

NOTE: For single-host systems using the R400X or B400X expander linked by a power bus cable, the Power switch on the VAX 4000 provides the power control bus signal to the expander(s). Setting the Power switch to on (1) on the VAX 4000 will cause the expander(s) to power on as well. The Power switch on the expander(s) should always remain in the on position (1).

When you turn on the power, you should see the indications listed in Table 2–1.

2–4 VAX 4000 Model 200 (BA430) Operation

Table 2–1: Normal Power-Up Indications

If you do not observe the indications in Table 2–1, refer to VAX 4000 Model 200 Troubleshooting and Diagnostics.

Every time you turn on your system, it runs a series of self-tests on the CPU and memory. Your console terminal ﬁrst displays a line of information identifying the CPU, the version of the ﬁrmware, and the version of VMB— the primary bootstrap program. In the sample screens provided in this chapter, the CPU is identiﬁed as a KA660–A, and the versions of the ﬁrmware and primary bootstrap are indicated as n.n. Your system will display actual version numbers. The console terminal then displays a countdown as the system tests itself. When the self-tests are successful, the system either autoboots system software or goes into console mode, as described in Sections 2.4.1 and 2.4.2.

2.4 Booting the System

VAX 4000 systems boot in one of two ways. You can conﬁgure the system to autoboot on power-up or you can manually boot the system from console mode. The Break Enable/Disable switch setting determines how the system boots.

2.4.1 Autobooting the System

When the Break Enable/Disable switch is set to disable (the normal operating setting), the system runs self-tests and, on completion, attempts to load system software. Additionally, if the Break Enable/Disable switch is set to enable, and the halt action REBOOT or RESTART_REBOOT has been deﬁned using the SET HALT command, the system will automatically attempt to load system software.

Depending on whether or not a boot device has been selected, the system loads system software or prompts you to select a boot device.

Loading System Software (with Boot Device Selected)

When a boot device has been selected, the system identiﬁes the boot device and the number 2 displays on the screen. As the system begins booting, the countdown continues from 1 to 0.

Changing the Boot Device

Once a boot device is identiﬁed, the system autoboots from that device each time you turn it on, until you do one of the following:

• Change the setting of the Break Enable/Disable switch to enable (up, dot inside the circle). If you do so, the system will not autoboot but will enter console mode after completing self-tests (assuming you have not deﬁned a halt action of REBOOT or RESTART_REBOOT using the SET HALT console command). Refer to Section 2.4.2 for instructions on booting from console mode.

• Change the boot device by using the SET BOOT command.

Operating the System 2–9

Using the SET BOOT Command

To direct the system to boot automatically from a speciﬁc device or to change the setting of the default boot device, put the system into console mode and at the prompt (>>>), enter ‘‘SET BOOT device-name’’. For example,

>>>SET BOOT EZA0 sets the system default boot device to be the Ethernet controller. Once you have selected a boot device, the system autoboots from that device

each time you turn it on. Using ‘‘SET BOOT device-name,device-name,device-name’’, you can also

specify a string of default boot devices (up to 32 characters, with devices separated by commas and no spaces) for which the system will check for bootable software. The system checks the devices inthe order speciﬁed and boots from the ﬁrst one that contains bootable software. For example,

>>>SET BOOT DUA0,DIA0,MIA0,EZA0 directs the system to use DUA0, DIA0, MIA0, and EZA0 as the default

boot devices. When the system autoboots, or if the BOOT command is used without specifying a device, the system will boot from the ﬁrst default boot device that contains bootable software.

NOTE: If included in a string of boot devices, the Ethernet device, EZA0, should only be placed as the last device of the string. The system will continuously attempt to boot from EZA0.

To determine the name of the device from which to boot the system, refer to Table 2–2 or enter the SHOW DEVICE command at the console prompt (>>>). Figure 2–6 shows a sample list of devices. The system displays the logical device name, preceded by a dash (–), for each device.

NOTE: Selecting a default boot device other than the Ethernet device, EZA0, is not appropriate for diskless and tapeless systems that must boot software over the network.

Loading System Software

To load system software from console mode, enter the BOOT command, ‘‘BOOT device name’’. For example,

>>>BOOT MUA0 tells the system to boot software from a cartridge in the TK70 tape drive. If you enter the BOOT command without specifying a device, the system

will attempt to boot from the default boot device or string ofdevices deﬁned by the SET BOOT command.

Using ‘‘BOOT device-name,device-name,device-name’’, you can also specify a string of boot devices (up to 32 characters, with devices separated by commas and no spaces) for which the system will attempt to boot software. The system checks the devices in the order speciﬁed and boots from the ﬁrst one that contains bootable software. For example,

>>>BOOT DUA0,DIA0,MIA0,EZA0 directs the system to boot from the ﬁrst device in the list that contains

bootable software.

NOTE: If included in a string of boot devices, the Ethernet device, EZA0, should only be placed as the last device of the string. The system will continuously attempt to boot from EZA0.

2–12 VAX 4000 Model 200 (BA430) Operation

NOTE: To determine the name of the device from which to boot the system, refer to Table 2–2.

Software manuals may instruct you to power up with break enabled and to use the BOOT command.

2.5 Using the System

Once the system software is loaded, the ﬁrst display for the system software appears on the console terminal after a few seconds. That display is described in the system software documentation.

You are now ready to use the system. Refer to the system software manuals and application manuals for more speciﬁc instructions on using the system.

Your system software manuals cover the following:

• Installing software on your system

• Running software to perform tasks

• Making and restoring backup copies of system software or data ﬁles

• Accessing devices and utilities in your system

2.6 Halting the System

Halting the system interrupts all processes and returns control to the console program. You may need to halt the system during software installation. Or, you may want to boot the system from another device; for example, a tape cartridge containing MicroVAX Diagnostic Monitor (MDM) software.

CAUTION: Halting your system without following the shutdown procedure described in your system software manuals may result in loss of data.

You can halt the system in two ways:

• You can press the Halt button twice—in to halt the system and out to enter console mode.

• If the Break Enable/Disable switch on the CPU cover panel is set to enable (up, dot inside the circle), you can press the

Break

key on the console terminal. If the Break Enable/Disable switch is not set to enable and you wish to halt the system by pressing

Break

, change the setting

of the Break Enable/Disable switch from disable to enable.

Operating the System 2–13

NOTE: You can use the console command SET CONTROLP to specify the control character,

Ctrl/P

, rather than

Break

, to initiate a break signal.

CAUTION: If you shut off your console terminal while breaks are enabled, the system interprets the action as a break, and the system halts.

If you are using a system that is part of a VAXcluster, do not halt, restart, or turn off the system without consulting the cluster manager. Performing any of these activities will interrupt the processes of the entire cluster.

When the console mode prompt (>>>) is displayed on your screen, the system is halted.

If you inadvertently halt the system, enter c

Return

at the console prompt.

The processes interrupted by the halt will continue.

2.7 Restarting the System

NOTE: Restarting the system aborts all current and pending operations. To

prevent loss of data, warn all users to log off before restarting the system. Follow the shutdown procedure described in your system software manuals before restarting the system.

Restarting returns the system to a power-up condition. All current and pending operations are aborted and the usual power-up tests are run.

You restart the system by pressing the Restart button on the system control panel.

NOTE: The Halt button must be out (not lit) to effect a restart operation.

2.8 Turning Off the System

CAUTION: Turning off your system without following the shutdown

procedure described in your system software manuals may result in loss of data.

Once you have completed the recommended procedure, you can turn off your system by setting the Power switch to 0.

NOTE: For systems expanded with the R400X or B400X expander and linked by a power bus cable, you need only turn off the system unit. The expander(s) will power off when you set the system Power switch to off (0). Note that the orange ac indicator on the expander power supply should remain lit even though the system is powered off.

2–14 VAX 4000 Model 200 (BA430) Operation

2.9 Recovering from an Over Temperature Condition

If your system’s internal temperature approaches a level that may cause components to overheat, an audible alarm will sound and the Over Temperature Warning indicator on the SCP will ﬂash. If the temperature continues to increase, the system will automatically shut down.

When the system shuts down due to overheating, the Over Temperature Condition indicator on the power supply remains lit. To recover from a shutdown, set the Power switch to off (0) and wait 5 minutes before turning on the system.

To prevent an over temperature condition, use the following precautions:

• Make sure your system is away from heat sources.

• Check that the system’s air vents are not blocked.

• Check that the room temperature is within acceptable limits as speciﬁed

in your VAX 4000 Site Preparation manual.

Chapter 3

Operating the System Options

This chapter describes how to use options that may already be part of your system, or that you can add to your system. The following types of options are covered:

• Mass storage devices and controllers

• Communications controllers

• Real-time controllers

• Printers

NOTE: Some variants of these options may not be appropriate for VAXserver 4000 systems. Contact your Digital representative if you have any questions about whether a speciﬁc option is appropriate for your system.

3.1 Mass Storage Options

The following mass storage options are included with VAX 4000 systems:

• RF-series Integrated Storage Element (ISE)

• TF85, TK70, or TLZ04 tape drive

NOTE: In addition, the RV20 Optical Disk Subsystem, RRD40-series Compact Disc Drive Subsystem, TSZ07, TSV05, and TU81E tape drives can be attached to the VAX 4000 system. If your system contains one of these options, refer to the user’s guide or owner’s manual for instructions on how to operate the device.

This chapter describes how to use the controls for the RF-series ISEs and the TF85, TK70, and TLZ04 tape drives. In the case of the tape drives, it also describes how to insert and remove the tape cartridge. To use any mass storage device, you must properly identify the device to the operating system and use appropriate operating system commands. Refer to your system software documentation for details.

Operating the System Options 3–1

3.1.1 RF-Series Integrated Storage Elements

Your system may have up to four RF-series ISEs or up to three RF-series ISEs and a tape drive. When your system has multiple ISEs, Digital recommends that you separate them according to function. For example, if your system has two ISEs, you may want to use them as follows:

• ISE 0 contains the operating system and applications installed on the

system.

• ISE 1 contains work areas for each user with an account on the system.

The storage capacities and other speciﬁcations for RF-series ISEs are listed in VAX 4000 Model 200 Technical Information.

Refer to Appendix B for information on setting or examining parameters for DSSI devices.

3.1.1.1 RF-Series Controls and Indicators

Each RF-series ISE has controls and indicators on its front panel: To access the ISE controls you need only open the upper door (top key position). Figure 3–1 shows the front panel of an RF-series ISE.

NOTE: If your system has less than the maximum number of ISEs: three if you have a TK70 tape drive, or four without the tape drive, a blank ISE front panel with no controls or indicators is used to cover the empty ISE cavities. The front panels are required to meet international regulatory standards.

3.1.1.2 Changing the Bus Node ID Plugs

Spare bus node ID plugs are supplied with your system. Use the spare plugs when you add ISEs, reconﬁgure your system with an expander, or create a dual-host conﬁguration.

The bus node ID plugs have prongs on the back that indicate the bus node number (and by default, the unit number) of the ISE. To remove a busnode ID plug, grasp it ﬁrmly and pull straight out. To insert a bus node ID plug, align the two center prongs with the two center slots and press the plug into the slots. See Figure 3–2.

Use the rules below for renumbering your storage elements:

• For each DSSI bus, do not duplicate bus node numbers for your storage

elements. You can have only one storageelement identiﬁed as bus node 0, one storage element as 1, and so on.

• By convention, the ISEs are numbered in increasing order from right

to left.

Operating the System Options 3–5

NOTE: If you change the bus node ID plugs while the system is operating, you must turn off the system and then turn it back on for the new plug addresses to take effect.

3.1.2 TF85 Tape Drive

The TF85 tape drive is located behind the upper door of the system. To use the drive, move the key to the top position and open the door.

The TF85 tape drive holds one removable magnetic tape cartridge. The drive can read data written on either a CompacTape III, CompacTape II, or CompacTapecartridge; but cannot write to a CompacTapeII or CompacTape cartridge. You must use a CompacTape III cartridge to make copies or backups of software or data. You can identify the type of cartridge by the label on the cartridge. Table 3–2 shows cartridge compatibility with the TF85 tape drive.

NOTE: The TF85 can read cartridges recorded by TK-series tape drives.

The tape drive has two primary controls: the cartridge insert/release handle (subsequently referred to as the ‘‘handle’’) and the Unload button. You use the handle to insert or remove cartridges and lock them into position. Pull the handle open to insert or remove a tape cartridge. Push the handle closed to lock a tape cartridge into position and load the tape.

You use the Unload button to rewind and unload the tape. Rewinding and unloading can also be controlled by software. Refer to your system software manuals for appropriate commands.

A bus node ID plug on the drive’sfront panel identiﬁes the bus node number of the device to the system as well as the unit number by default.

NOTE: Refer to Appendix B for information on setting or examining parameters for DSSI devices.

The drive also has four indicator lights that show the status of the drive.

To operate the drive properly, you must carefully monitor the indicators. The instructions for inserting and removing cartridges, which appear later in this section, tell you what should happen at each step. A table at the end of the section summarizes indicator and control combinations.

Operating the System Options 3–7

3.1.2.1 Design of the Drive

The TF85 tape drive operates like a reel-to-reel tape deck. Inside the drive is a take-up reel with a leader attached. Inside the cartridge is a single reel containing the magnetic tape. When you insert the cartridge and push in the handle, the leader in the drive automatically couples with the leader in the cartridge, and the tape winds onto the take-up reel. The coupling and winding process is called loading. When the automatic loading process is complete, the tape is ready to use.

Once the cartridge is loaded, you cannot remove it without rewinding and uncoupling the leaders, a process called unloading. Even if you have not used the tape, you must unload it before you can remove the cartridge. When you press the Unload button, the tape rewinds into the cartridge and the leaders uncouple.

3.1.2.2 Labeling a Tape Cartridge

When recording data on a cartridge, label its contents. For your convenience, a slot for the label is provided on the front of the cartridge. Write the identiﬁcation on the label and insert the label in the slot on the front of the cartridge, as shown in Figure 3–4. The label is visible when the tape is in the drive.

MLO-000960

NOTE: Do not write on the tape cartridge or attach labels to the top, bottom, or sides of the cartridge.

3.1.2.3 Write-Protecting a Tape Cartridge

Write-protectinga tape cartridge prevents accidental erasure of information stored on the tape. You can write-protect a tape cartridge in two ways:

• Set the write-protect switch on the cartridge to the write-protect

position.

• Write-protect the cartridge by using operating system commands

described in your system software manuals.

Operating the System Options 3–9

Your system can read information on the tape regardless of the position of the write-protect switch or whether writing is software disabled. However, the system cannot write data to the tape when the write-protect switch is set to the write-protect position, or when writing is software disabled.

When you use a cartridge to install software, make sure the cartridge is write protected. Two icons on the switch indicate the write-protect status, as shown in Figure 3–5. An orange rectangle is visible when the switch is in the write-protect position. If you do not see an orange rectangle, slide the switch toward the label slot.

When you insert a write-protected cartridge into the drive, the orange writeprotected indicator lights. The system recognizes the tape as being writeprotected under any one of the following conditions:

• The write-protect switch on the cartridge is set to the write-protect

position.

• An operating system command has write-protected the tape.

• A tape recorded on a TK-series tape drive is inserted into the drive. Removing write-protection depends on how the tape was recorded and how

it is write protected. You cannot write-enable a tape recorded on a TK50 /TK70 tape drive either by moving the write-protect switch onthe cartridge or by using software commands. The TF85 tape drive always recognizes a tape recorded on a TK50/TK70 drive as write-protected. You can remove write-protection on tapes recorded on a TF85 tape drive as follows:

• If the cartridge is write protected only by the write-protect switch on the

cartridge and not the operating system, moving the switch to the write-

enabled position causes the write-protect indicator light to go out.

3–10 VAX 4000 Model 200 (BA430) Operation

Figure 3–5: Tape Cartridge Write-Protect Switch

WriteProtected

Not WriteProtected

MLO-000961

• If the cartridge is write protected only by a software command and

not the write-protect switch, removing the operating system restriction

causes the write-protect indicator to go out.

• If the cartridge is write protected by both the switch on the cartridge

and a software command, you must change the switch setting and

remove the operating system restriction.

Operating the System Options 3–11

When you use a CompacTape III cartridge to make a backup copy of ﬁles, make sure the orange write-protect indicator on the TF85 is off. If the indicator is not off, check for any of the write-protect conditions described above. Change the switch setting and/or operating system restriction as necessary. Do not begin your operation until the write-protect indicator goes off.

• Do not touch the exposed surface of the tape.

• Do not drop the tape cartridge. The impact from a fall can damage the

tape cartridge.

• Allow new tapes to stabilize at room temperature for 24 hours before

using them.

• Place an identiﬁcation label only in the label slot on the front of the

tape cartridge.

• Store tape cartridges in a dust-free environment.

• Keep tape cartridges away from direct sunlight, heaters, and other

sources of heat. Store tape cartridges in a stable temperature between

10° and 40°C (50° and 104°F).

• Store tape cartridges where the relative humidity is between 20 and 80

percent.

• Keep tape cartridges away from magnets and equipment that generate

magnetic ﬁelds, such as motors, transformers, terminals, and audio

equipment.

• Keep tape cartridges away from x-ray equipment.

3.1.2.4 Inserting a Tape Cartridge

Before you use the tape drive, make sure the system is turned on. During power-up, the TF85 drive runs self-tests that last a few seconds. All four indicator lights come on momentarily, then the yellow (Tape in Use) indicator blinks during the self-tests. At the end of the tests, the yellow indicator goes off and the green (Operate Handle) indicator comes on, accompanied by a short beep. The green indicator and the beep indicate that you can move the cartridge release handle.

CAUTION: Move the handle only when the green indicator light is on. Moving the handle while the yellow indicator light is on could damage the drive. If all four indicators blink rapidly at any time, a fault condition exists. Press the Unload button once. If the fault is cleared, the tape unloads. The yellow indicator blinks during unloading, then the green indicator comes on. If the fault is not cleared, the four indicators continue to ﬂash. Do not

3–12 VAX 4000 Model 200 (BA430) Operation

attempt to use the tape drive or to remove the tape cartridge. Call your Digital service representative.

Use the following procedure to insert a tape cartridge (see Figure 3–6):

1. Pull the handle open.

2. Position the cartridge so the arrow on the cartridge faces left and points

toward the drive. Insert the cartridge into the tape drive until you feel

the cartridge lock into place.

3. Push the handle closed.

The green indicator goes off and the yellow indicator blinks as the tape

loads. When the yellow indicator glows steadily, the tape is ready to

use.

NOTE: If the green indicator blinks rapidly when you push the handle

closed, the drive has detected a cartridge fault. Pull the handle open

and remove the cartridge. Use another cartridge.

Refer to Appendix C for instructions on how to create backup ﬁles ona tape cartridge.

NOTE: If a cartridge is new, the drive performs a calibration sequence that takes approximately 30 seconds when the drive receives the ﬁrst command from the operating system. The yellow indicator blinks rapidly and irregularly during calibration.

3.1.2.5 Removing a Tape Cartridge

You must unload a tape before you can remove the cartridge from the tape drive. Use the following procedure (see Figure 3–7):

1. Press the Unload button. You can also issue a software command to

unload the cartridge. Refer to your system software manuals for the

appropriate command.

The yellow (Tape in Use) indicator blinks slowly, as the tape rewinds

and unloads into the cartridge. This may take up to 90 seconds.

2. When the yellow indicator goes off and the green (Operate Handle)

indicator comes on (you also hear a beep), pull the handle open.

CAUTION: Move the handle only when the yellow indicator is off and

the green indicator is on. Moving the handle while the yellow indicator

is blinking could damage the drive.

3. Remove the tape cartridge and store it in its container.

4. Push the handle closed. The green indicator light remains on, indicating that there is power to the

drive and that you can safely move the handle.

CAUTION: Remove the tape cartridge from the tape drive when the cartridge is not in use or before you turn off the system. Failure to remove the cartridge may damage the tape cartridge.

3.1.3 TK70 Tape Drive

The TK70 tape drive is located behind the upper door of the system. To use the drive, move the key to the top position and open the door.

The TK70 tape drive holds one removable magnetic tape cartridge. The drive can read data written on either a CompacTape II or CompacTape cartridge. You can identify the type of cartridge by the label on the cartridge.

You can use a CompacTape II or CompacTape cartridge as an input device to load software or data into your system. The TK70 drive can read data on both types of cartridges, written by either aTK70 drive or a TK50 drive. (The TK50 drive records data in a format different from that of the TK70.)

3–18 VAX 4000 Model 200 (BA430) Operation

You should use a CompacTape II as an output device to make copies or backups of software or data. The TK70 drive cannot write to a CompacTape II or CompacTape that has been previously written by a TK50 tape drive.

TK70 Tape Drive Controls

You use the Unload button to rewind and unload the tape. Rewinding and unloading can also be controlled by software. Refer to your system software manuals for appropriate commands.

The drive also has three indicator lights that show the status of the drive.

• Orange light (Write Protected): A steady orange light shows the

cartridge is write protected.

• Yellow light (Tape in Use): A steady yellow light shows the tape is

loaded. A blinking yellow light shows the tape is in motion.

• Green light (Operate Handle): A steady green light shows you can move

the handle to insert or remove a tape. A blinking green light shows a

cartridge load fault. You can also move the handle when the green light

is blinking. All three lights blinking simultaneously indicate a fault condition. Figure 3–8 shows the TK70 tape drive with the controls and indicator lights

labeled. To operate the drive properly, you must carefully monitor the indicator

lights. The instructions for inserting and removing cartridges, which appear later in this section, tell you what should happen at each step. A table at the end of the section summarizes light and control combinations.

3.1.3.1 Design of the Drive

The TK70 tape drive operates like a reel-to-reel tape deck. Inside the drive is a take-up reel with a leader attached. Inside the cartridge is a single reel containing the magnetic tape. When you insert the cartridge and push in the handle, the leader in the drive automatically couples with the leader in the cartridge, and the tape winds onto the take-up reel. The coupling and winding process is called loading. When the automatic loading process is complete, the tape is ready to use.

3.1.3.2 Labeling a Tape Cartridge

When recording data on a cartridge, label its contents. For your convenience, a slot for the label is provided on the front of the cartridge. Write the identiﬁcation on the label and insert the label in the slot on the front of the cartridge, as shown in Figure 3–9. The label is visible when the tape is in the drive.

Figure 3–9: Labeling a Tape Cartridge

Label Slot

MLO-000960

To indicate that the tape was recorded on a TK70 tape drive, check the box labeled 296MB. The 95MB box is used for tapes recorded on a TK50 drive.

NOTE: Do not write on the tape cartridge or attach labels to the top, bottom, or sides of the cartridge.

3.1.3.3 Write-Protecting a Tape Cartridge

Write-protectinga tape cartridge prevents accidental erasure of information stored on the tape. You can write-protect a tape cartridge in two ways:

• Set the write-protect switch on the cartridge to the write-protect

position.

Operating the System Options 3–21

• Write-protect the cartridge by using operating system commands

described in your system software manuals. Your system can read information on the tape regardless of the position of

the write-protect switch or whether writing is software-disabled. However, the system cannot write data to the tape when the write-protect switch is set to the write-protect position, or when writing is software disabled.

When you use a cartridge to install software, make sure the cartridge is write-protected. Two icons on the switch indicate the write-protect status, as shown in Figure 3–10. An orange rectangle is visible when the switch is in the write-protect position. If you do not see an orange rectangle, slide the switch toward the label slot.

When you insert a write-protected cartridge into the drive, the orange indicator light comes on. The system recognizes the tape as being writeprotected under any one of the following conditions:

• The write-protect switch on the cartridge is set to the write-protect

position.

• An operating system command has write-protected the tape.

• A tape recorded on a TK50 tape drive is inserted into the drive. Removing write-protection depends on how the tape was recorded and

how it is write protected. You cannot write-enable a tape recorded on a TK50 tape drive either by moving the write-protect switch on the cartridge or by using software commands. The TK70 drive always recognizes a tape recorded on a TK50 drive as write-protected. You can remove writeprotection on tapes recorded on a TK70 drive as follows:

• If the cartridge is write protected only by the write-protect switch on

the cartridge and not the operating system, moving the switch to the

write-enabled position causes the orange light to go out at the end of

the executing command.

3–22 VAX 4000 Model 200 (BA430) Operation

Figure 3–10: Tape Cartridge Write-Protect Switch

Not WriteProtected

MLO-000961

• If the cartridge is write protected only by a software command and

not the write-protect switch, removing the operating system restriction

causes the orange light to go out.

• If the cartridge is write protected by both the switch on the cartridge

and a software command, you must change the switch setting and

remove the operating system restriction.

Operating the System Options 3–23

When you use a CompacTape II cartridge to make a backup copy of ﬁles, make sure the orange write-protect light on the TK70 drive is off. If the light is not off, check for any of the write-protect conditions described above. Change the switch setting and/or operating system restriction as necessary. Do not begin your operation until the orange light goes off.

3.1.3.4 Tape Cartridge Handling and Storage Guidelines

• Do not touch the exposed surface of the tape.

• Do not drop the tape cartridge. The impact from a fall can damage the

tape cartridge.

• Allow new tapes to stabilize at room temperature for 24 hours before

using them.

• Place an identiﬁcation label only in the label slot on the front of the

tape cartridge.

• Store tape cartridges in a dust-free environment.

• Keep tape cartridges away from direct sunlight, heaters, and other

sources of heat. Store tape cartridges in a stable temperature between

10° and 40°C (50° and 104°F).

• Store tape cartridges where the relative humidity is between 20 and 80

percent.

• Keep tape cartridges away from magnets and equipment that generate

magnetic ﬁelds, such as motors, transformers, terminals, and audio

equipment.

• Keep tape cartridges away from x-ray equipment.

3.1.3.5 Inserting a Tape Cartridge

Before you use the tape drive, make sure the system is turned on. During power-up, the TK70 drive runs self-tests that last a few seconds. All three lights (orange, yellow, and green) come on momentarily, then the yellow (Tape in Use) light blinks during the self-tests. At the end of the tests, the yellow light goes off and the green (Operate Handle) light comes on, accompanied by a short beep. The green light and the beep indicate that you can move the cartridge release handle.

CAUTION: Move the handle only when the green indicator light is on. Moving the handle while the yellow light is on could damage the drive. If all three lights blink rapidly at any time, a fault condition exists. Press the Unload button once. If the fault is cleared, the tape unloads. The yellow light blinks during unloading, then the green light comes on. If the fault

3–24 VAX 4000 Model 200 (BA430) Operation

is not cleared, the three lights continue to ﬂash. Do not attempt to use the tape drive or to remove the tape cartridge. Call your Digital service representative.

Use the following procedure to insert a tape cartridge (see Figure 3–11):

1. Pull the handle open.

2. Position the cartridge so the arrow on the cartridge faces left and points

toward the drive. Insert the cartridge into the TK70 tape drive until

you feel the cartridge lock into place.

3. Push the handle closed.

The green light goes off and the yellow light blinks as the tape loads.

When the yellow light glows steadily, the tape is ready to use.

NOTE: If the green light blinks rapidly when you push the handle

closed, the drive has detected a cartridge fault. Pull the handle open

and remove the cartridge. Use another cartridge.

Refer to Appendix C for instructions on how to create backup ﬁles ona tape cartridge.

NOTE: If a cartridge is new, the drive performs a calibration sequence that takes approximately 30 seconds when the drive receives the ﬁrst command from the operating system. The yellow light blinks rapidly and irregularly during calibration.

3.1.4 TLZ04 Tape Drive

The TLZ04 tape drive is located behind the upper door of the system. To use the drive, move the key to the top position and open the door.

The TLZ04 tape drive is a back up device that uses digital data storage (DDS) and digital audio tape (DAT) recording technologies. Digital audio tape, such as TLZ04 cassettes, takes advantage of the TLZ04 tape drive’s helical scan technology. This technology allows more data to be stored on tape by recording data diagonally. DAT recording also minimizes ‘‘crosstalk,’’ providing you with higher data integrity.

Digital data storage uses a recording format that supports the use of digital audio tape for computer applications. The DDS/DAT format allows you to back up 1.2 gigabytes of data in approximately 2 hours with no operator intervention. In addition, this format has three levels of error correction, which ensures high data integrity.

3.1.4.5 Cleaning the Heads

Statistics show that more than 90 percent of drive-related problems are associated with the media. Therefore, Digital Equipment Corporation strongly recommends that you follow the instructions for handling cassette tapes and cleaning the heads of the drive.

This section shows you how to perform TLZ04 head cleaning. The heads are the components, in a drive, that magnetically read and write data to and from the media (in this case, a cassette tape).

NOTE: Digital Equipment Corporation recommends that you perform the head cleaning procedure about every two weeks, or after every 25 hours of drive usage.

Under normal conditions, it should not be necessary to exceed this cleaning schedule. If a particular cassette causes problems, try changing to another cassette.

CAUTION: Never attempt to clean the heads in a manner other than described herein. Doing so will void the product warranty.

To clean the heads, use the head cleaning cassette as follows:

1. Observe that the drive indicator is lit solid green.

2. Insert the head cleaning cassette (part number TLZ04–HA) into the

drive as shown in Figure 3–16.

3. With the head cleaning cassette inserted, the drive automatically

cleans the head. The drive ejects the head cleaning cassette after approximately 30 seconds.

4. In the space provided on the card enclosed with the head cleaning

cassette, place a check mark every time you use the head cleaning cassette.

Under normal conditions, the head cleaning cassette performs for approximately 25 cleanings. Additional cassettes are available from your Digital sales representative or DECdirect.

If the head cleaning cassette has been used more times than it was designed to be used, the drive will eject the cartridge in approximately 8 to 10 seconds. No cleaning action will occur.

CAUTION: Do not exceed the recommended 25 uses of the cleaning cassette. After 25 uses, the cleaning cassette no longer cleans the heads. You must use a new cassette.
