CARTRIDGE HOLDER AT THE FRONT OF THIS MANUAL.

This cartridge contains maintenance system software used to test your

Micro VAX. Before you insert the cartridge into the drive, you should do three things.

1. M,ake sure the cartridge is write-protected.

2. Check the position of the tape leader inside the cartridge.

3. Check the position of the tape leader inside the drive.

Setting the Write-Protect Switch

You make sure the cartridge is write-protected by checking the position of the write-protect switch, located next to the label. An orange rectangle is visible when the switch is in the write-protected position. If you do not see an orange rectangle, slide the write-protect switch towards the label as shown in the following figure.

Checking the Cartridge Leader

When you insert the cartridge into the drive, a tape leader on the take-up reel couples with a leader in the cartridge, much as you thread a needle. The arrow-shaped leader in the drive goes through the eye on the cartridge leader.

On rare occasions, shipping or rough handling may jar either leader out of position. This can damage your tape drive, as explained more fully in the

Operation chapter. To prevent such damage, we suggest you check both leaders before inserting the cartridge.

To check the cartridge leader, open the door in the back of the cartridge. With your thumb, lift the door lock (as shown below) and press on the hinge. The door swings open.

(RE LEASE BY LI FTING

The tape leader should appear exactly as shown with most of the leader eye visible.

If

DO NOT LOAD THE CARTRIDGE INTO YOUR TAPE DRIVE. DO NOT

TRY TO ADJUST THE LEADER. Contact your service representative for another diagnostic cartridge. If the leader appears normal, close the door and proceed.

1-19

Installation

Checking the Drive Leader

To check the leader in the drive, look inside the drive (you may need to use a light). You should look for two things.

1.

The pointed end of the leader should be clearly visible and straight (not bent up or down).

2. The leader should be hooked onto the bucking link, as shown below.

TURNING THE SYSTEM OFF

• Follow the system shut-down procedure described in your system software manual. That procedure will insure an orderly system shut-down that will prevent accidental loss of data.

• Turn the system off by setting the power 1/0 switch to the 0 (off) position.

MAKING BACKUP COPIES

A backup copy is a copy of files stored on the fixed disk, diskette, or tape.

You should make backup copies of files to insure against accidental loss of information. As a general rule:

• Make backup copies on diskettes or magnetic tape.

• Make a daily backup copy of all information you create or change that day.

• Make a weekly backup copy of all information stored on your fixed disk.

• Store all backup copies in a safe place.

Make backup copies of files you use with the system software as directed in the manual supplied with the system software.

Operation

TK50 TAPE DRIVE

The TK50 tape drive (referred to as drive 1) holds one removable TK50 magnetic tape cartridge. You can use a cartridge as both an input and output device. As an input device, you use it to load software or data onto your system. As an output device, you use it to make copies (or backups) of software or data, or as a journaling device to record input to the system. Each tape cartridge holds 94.5 megabytes (94.5M bytes) of information, more than

100 times the capacity of a diskette.

The tape drive has two primary controls: the cartridge release handle and the

LoadIU nload button. You use the cartridge release handle to insert/remove cartridges and lock them into position. You use the LoadIU nload button to control winding/rewinding of the tape.

The drive also has two indicator lights that let you know the status of the drive. A red light is part of the LoadlUnload button. A green light is at the opposite end of the drive. See the figure below for the location of the TK50 tape drive in your system. The controls and lights are labeled.

To operate the drive properly, you must carefully monitor the status lights.

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

2-16

Operation

Design of the Drive

The TK50 drive operates much 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 press the

Load button, two things occur: 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 completes, the cartridge 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 LoadlUnload button, the tape rewinds into the cartridge and the leaders uncouple.

The two tape leaders are coupled much like you thread a needle. The leader in the cartridge has a large eye with a notch. The leader in the drive is arrow-shaped. See the figure below.

CARTRIDGE

LEADER

NOTCH

RELATIVE

DRIVE

LEADER

MLO-283-86

The process proceeds in two steps:

1. When you insert a cartridge, the leader in the drive first threads through the eye of the cartridge leader.

2. When you press the LoadlUnload button, the take-up reel begins to move, and the drive leader catches in the notch and pulls the tape onto the takeup reel.

2-17

Operation

Because the position of each leader is critical to successful coupling, you should make sure they are properly positioned.

Although rare, rough handling during shipment can dislodge the cartridge leader. We therefore advise you to check the leader whenever you use a new cartridge. The Installation chapter tells you how to do this. An improperly positioned cartridge leader can damage your drive by displacing the leader on the take-up reel. If you always check new cartridges, you can prevent problems with the drive. Also if you drop a cartridge, check the leader before using it again.

You should check the leader in the drive in the following situations: when you first install your system (as described in the Installation chapter), if your system has been moved, or if you are having load/unload problems.

Labeling a Tape Cartridge

Always label your cartridge. For your convenience a slot for the label is provided on the front of the cartridge. This label is visible when the tape is in the drive. Labels or markings on any other part of the cartridge can interfere with proper operation of the drive.

• Write the desired identification on the label.

• Insert the label in the slot on the front of the cartridge.

• Do not apply stick-on labels to the top, bottom, or sides of the cartridge.

• Do not write on the tape cartridge with a pen or pencil.

LABEL

2-18

Operation

Write-Protecting a Tape Cartridge

Write-protecting a tape cartridge prevents accidental erasure of information stored on the tape. You set the write-protect status with a two-position switch on the cartridge. Your system can read information on the tape regardless of the position of the write-protect switch. However, it cannot write data to the tape when the write-protect switch is set to the write-protected position.

Whenever you use a cartridge to install software onto your system, make sure the write-protect switch on the front of the cartridge is in the writeprotected position. The switch has two icons indicating the write-protect status as shown in the figure below. An orange rectangle is also visible when the switch is in the write-protected position. If you do not see an orange rectangle, slide the switch towards the label slot.

,

WRITE-

~

M LO·28586

NOTE

Early versions of the cartridges do not have the orange rectangle.

Use the icons as guides.

When you use a cartridge to make a backup copy, to write out data, or to function as a journaling device, make sure the write-protect switch is set to enable writing to the tape. To enable writing, slide the switch away from the label slot until it locks into place.

2-19

Operation

Generally, you set the write-protect switch before you insert the cartridge into the drive. You can change the write-protection status of the tape while it is in the drive, but the TK50 may not recognize it immediately, depending on what activity is occurring. To guarantee that it recognizes the change in status, do the following:

1. Unload the tape by pushing the LoadIU nload button. Both the red and green lights flash while the tape is rewinding. The red light comes on steady as the tape unloads into the cartridge. When completely unloaded, the red light goes off and the green light comes on.

2. Move the write-protect switch to the desired position.

3. Push the LoadIU nload button to reload the tape. The red light comes on while loading. When the green light also comes on, the tape is ready to use.

The drive now recognizes the new write-protect status.

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 any new tapes to stabilize at room temperature for 24 hours before using them.

• Write on the identification label before putting the label on the tape cartridge. Place the 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 an even temperature between 50 and 104 degrees F (10 to 40 degrees C). 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, and terminals.

• Keep tapes away from x-ray equipment.

2-20

Operation

Inserting a Tape Cartridge

Make sure the system power 1/0 switch is set to 1 (on) and the LoadlUnload button is out.

The LoadlUnload button glows red for approximately 4 seconds during the tape drive power-on self test.

The red light goes off and the green light comes on, indicating that it is safe to move the cartridge release handle.

Never move the cartridge release handle while either indicator light is flashing.

If the red light flashes rapidly at any time, press the Load/Unload button four times. If the problem persists, do not attempt to use the tape drive or to remove the tape cartridge. Call your nearest service representative.

2-22

Operation

Removing a Tape Cartridge

You must unload a tape (includes rewinding and uncoupling) before you can remove the cartridge from the tape drive. Use the following procedure.

1. Press the LoadfUnload button to the out (unload) position.

The red and green lights flash slowly, but not in unison, as the tape rewinds to the beginning of the tape. This may take up to 90 seconds.

The red light remains on and the green light goes off, as the tape unloads into the cartridge.

When the tape is completely unloaded, the red light goes off and the green light comes on.

2. Pull the cartridge release handle up.

NOTE

Rewinding a tape can also be done under software control. Refer to your software manual for information.

3. Remove the tape cartridge and store it in a safe place.

4. Push the cartridge release handle down.

The green light remains on showing that there is power to the drive and that you can safely move the cartridge release handle.

CAUTION

Always 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 result in damage to the tape cartridge.

Troubleshooting is the process of isolating and repairing minor problems.

This section describes three levels of troubleshooting:

• Power-on messages - A list of indications that appear when the system is turned on and what they mean.

• Corrective actions - A simple checklist of potential problems and what to do.

• The Micro VAX Maintenance System - The maintenance tests available and when to use them.

3-1

Troubleshooting

POWER-ON MESSAGES

During the power-on sequence, the MicroVAX II executes built-in diagnostic and start-up routines that can give you useful maintenance information.

Monitoring the power-on display can warn you of possible problems. The information is displayed in the form of single letters, and numbers on the console terminal and on the LED display located on the CPU panel on the rear of the unit. Normally, the display will progress from F to 0, as listed in

Table 3-1.

If the display stops in the range of F to 3, there may be a hardware error in the system. Refer to

the Micro VAX II630QB Technical Manual.

If the display stops on 2, check the "system does not start from ... " problem indications listed in the Corrective Actions section of this chapter first. If the actions listed there do not solve the problem, refer to the

Micro VAX II 630QB

Technical Manual.

If the display stops on 1, the most likely problem is that the start-up device does not contain startable system software. Complete the system software installation as directed in the manual supplied with your system software.

CORRECTIVE ACTIONS

The corrective actions listed in this section are for minor problems that you can easily identify and correct. For example, an improper switch position can cause problems.

The types of problems you may encounter are grouped into three sections.

• Power-on problems - Table 3-2 lists problems that typically occur during power-on. These problems can occur whether or not you have already installed system software.

• Software installation problems - Table 3-3 lists problems that can occur during installation of diagnostic or system software.

• General problems - Table 3-4 lists problems that can occur at any time.

Corrective actions listed here assume a fairly simple cause. If these actions do not solve your problem, run the Micro VAX Diagnostics, described in the next section.

THE MICROVAX MAINTENANCE SYSTEM

The maintenance system software provides user tests that are designed to isolate and identify faults in the system. You can run the system test in response to an error message or to test your system periodically. These tests can detect more serious problems than those listed in the Corrective

Actions tables. Such problems as defective drives, defective controllers, bad connections between drives and controllers, and power supply problems are identified by the system test.

3-11

Troubleshooting

Before calling a service representative to report a problem, run the system test and record the results.

The maintenance system software is stored on RX50 diskettes or on a

TK50 magnetic tape cartridge. You run the maintenance system programs using the console terminal for command inputs and system displays. The

Installation chapter describes the system test. To run the test after your system software has been loaded, you must do the following:

1. Check that halts are enabled. The switch on the rear of the system should be set to the up position (dot inside the circle).

2. Press the <BREAK> key on the console terminal or the Halt button on the control panel. This puts your system into console command mode. You should see the > > > prompt.

3. If you are testing with a tape cartridge, press the Ready button on the control panel to the in position. This puts the fixed disk off-line so that your system will load the diagnostic software from the tape drive. This step is, not necessary if you are testing with diskettes.

4. Insert the medium containing the diagnostic software into the appropriate drive. If you are testing with a cartridge, use the cartridge labeled MVII

Diag. Cust. TK50. Be sure to press the LoadlUnload button. If you are testing with diskettes, start with the diskette labeled MVII Diag. Cust.

RX501.

5. Press the Restart button on the control panel to the in position. This restarts your system from the medium containing the diagnostic software.

After you see the introductory display of the Micro VAX Maintenance System, run the diagnostic tests as described in the Installation chapter beginning with step 21.

More serious problems require the use of the maintenance procedures described in the Micro VAX II 630QB Technical Manual. Those procedures should only be performed by qualified service personnel.

Appendix C

MicroVAX II Options

Additional hardware options are available for your Micro VAX II system.

Some of these options are customer-installable; others require a trained specialist.

For more information on options refer to Chapters 3 and 4 of the

MicroVAX

II630QB Technical Manual.

TERMINAL AND PRINTER OPTIONS

You can use any DIGITAL video or hard-copy terminal and any LA series printer with Micro VAX II systems. The Micro VAX II system supports terminals and printers that meet EIA standard RS--232C.

The number of terminals or printers that can be connected to your system depends on the model you have.

Some systems are equipped with communication options that allow connection of additional terminals and/or printers. Refer to the

MicroVAX II

630QB Technical Manual for details.

C-l

MicroVAX II Options

MEMORY OPTIONS

The Micro VAX II system can have up to two MS630 memory modules. Three variations are available.

Module Number

MS630-AA

MS630-BA

MS630-BB

MS630-CA

Capacity

1M byte

2M bytes

4M bytes

(8M bytes)

NOTE

On systems with 16 MB of memory, it may take up to three minutes to perform the self-tests when you turn on the system.

MICROVMS PROBLEMS WITH 8 MB MEMORY BOARDS

Every time you turn on your Micro VAX II, it first runs self-tests on the hardware, then tries to load system software from a fixed disk. If you have

Version 4.4 (or earlier) of Micro VMS installed on your system, Micro VMS reports some misleading error messages when one or two of the MS630-CA

(8 MB) memory options are installed. These problems will be solved in a future release of Micro VMS and do not affect how you use your system.

The error messages are described in the following sections.

Faulty SYSGEN parameter

When you boot a Micro VAX II system containing 16 MB of memory, you may receive the following error message:

%SYSBOOT-W-WS, default and quota raised to PHD+MINWSCNT

This message indicates that the PQL_DWSDEFAULT SYSGEN parameter is too low. You can ignore this message, as it does not affect the performance of your system.

Bootstrap Program Reports Faulty Memory Pages

When you boot Micro VMS on a Micro VAX II system, the primary bootstrap program checks all memory in the system. As part of that checking procedure, it reports bad pages of memory. In VMS, a page is an area of 512 contiguous bytes, the size of a block of data read into memory from mass storage.

C-2

MicroVAX " Options

If you issue a SROW MEMORY command on a system having more than

13MB of memory, VMS reports one bad page of memory. On systems having more than 16 MB of memory, VMS reports two bad pages of memory.

The report of bad pages is misleading. The pages of memory are not bad, but "in use" to support the video function. You can safely ignore the error message.
