Operation

The last part of the power-on display shows the numbers 2 through 0 to
indicate that the system is loading the system software. The first display for
the system software appears on the console terminal after a few seconds. The
display is described in the manual supplied with the system software.
If you do not see this sequence of events, refer to the Troubleshooting section
in this manual.
You are now ready to use the system. Refer to the system software manual for
further instructions on using the system.

2-9

Operation
TURNING THE SYSTEM OFF
1. 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.
2. Turn the system off by setting the power 110 switch to the 0 (off) position.

Operation

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.

2-11

Operation
RD52 OR RD53 FIXED-DISK DRIVE

The RD52 or RD53 fixed-disk drive is located inside the cabinet. Information
is stored on fixed (nonremovable) disks.
The RD52 fixed disk stores up to 31M bytes of data. The RD53 fixed disk
stores up to 71M bytes of data.
The fixed disk is referred to as drive 0.

RXSO DISKETTE DRIVE
~

The RX50 dual disk drive holds two 5.25-inch diskettes. Each diskette stores
400 kilobytes (400K bytes) of information, which is roughly 150 typewritten
pages.
An indicator light on each drive lights when the drive is in use.

RXSO Diskettes

• Information is stored magnetically.
• Information is stored on only one side of an RX50 diskette.
• Information stored previously can be erased and new information stored in
its place.
The diskette rotates inside its cover. The diskette is cleaned continuously by
the soft fabric lining of the cover.

Diskette Handling and Storage Guidelines

• Do not touch the exposed surfaces of the diskette.
• Always return a diskette to its protective envelope to keep out dust and
dirt.

• Do not bend or fold a diskette.
• Always store diskettes vertically and loosely to prevent the covers from
becoming warped.
• Write on the diskette label before applying it to the diskette. Writing on
the diskette might damage the diskette.
• Keep diskettes away from direct sunlight, heaters, and other sources of
heat.
• Keep diskettes away from magnets and equipment that generate magnetic
fields, such as motors, transformers, and terminals.
• Always close the drive door when using a diskette. The drive does not work
with the door open.

• Do not open the drive doors when the drive indicator lights are on.
Information could be lost.
• Make and keep backup copies of all working diskettes. Refer to your
system software manual for instructions.

2-16

Operation

Write-Protecting a Diskette

To prevent the system from accidentally adding, changing, or deleting
information on a diskette, cover the write-protect notch with one of the selfadhesive foil tabs supplied with your diskettes. This procedure is known as
write-protecting the diskette. You can later add or change information on the
diskette by removing the write-protect tab. The tab is illustrated below.

TKSO TAPE DRIVE

The TK50 tape drive (referred to as drive 1) holds one removable TK50
magnetic tape cartridge. Each tape cartridge holds 94.5 megabyt es (94.5M
bytes) of information.
• Information is stored magnetically.
• Information is stored on only one side of the tape. The tape cartridge must
be inserted correctly in the TK50 tape drive.
• Information stored previously can be erased and new information stor ed in
its place.

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 prerecorded 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.

CAUTION
Never move the cartridge release handle unless the red indicator
light is off and the green indicator light is on. Never lift the cartridge release handle while an 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.

Operation

Removing a Tape Cartridge

You must rewind and unload a tape before you can remove the tape cartridge
from the tape drive. Use the following procedure.
1. Press the Load/Unload button to the out (unload) position to rewind and
unload the tape.

The red and green lights flash slowly, but not in unison, as the tape
rewinds to the beginning of the tape.
The red light remains on and the green light goes off, as the tape unloads
into the cartridge.
When the tape is completely rewound in the cartridge, the red light goes
off and the green light goes on.
2. Push the cartridge release handle to the left.
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 to the right.
The green light remains on showing that there is power to the drive.
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

Troubleshooting is the process of isolating and repairing minor problems.
This section contains three parts:
• Corrective actions - A simple checklist of potential problems and what
to do.
• Power-on messages - A list of indications that appear when the system is
turned on and what they mean.
• The MicroVAX Maintenance System - This portion is divided into two
parts. The first describes the maintenance tests and maintenance utilities
and tells when to use them. The second discusses the main menu and
describes maintenance system options.

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. 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 ofF to 3, there may be a hardware error in
the system. Refer to the Micro VAX II 630QY, 630QZ Technical Manual.
If the display stops on 2, check the "system does not start from ... " problem
indications listed in the previous part of this section (Corrective Actions).
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.

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.
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.
Main Menu

The main menu lists three customer options available to all users who run
the maintenance system and two service options available only to those users
who have purchased a MicroVAX Maintenance Kit. You can obtain the main
