Using the Three–Button Mouse

The mouse is a hand–operated locating device. A three–button mouse is available
for use with the system unit.

Consult your application publication for the exact use of the three–button mouse.

You can use the mouse to perform such functions as positioning a cursor, selecting
items from a menu, or moving around in your document much easier and faster than
if you used only the keyboard. The cursor moves exactly as you move the mouse on
a flat surface, such as a desktop.

When you move the mouse around on a flat surface as shown in this illustration, the
cursor moves on the display screen; the movement changes the position of the
cursor.

IBM RS/6000 7025 F50 Series User's Guide

example, you can operate the mouse on the following surfaces:

 Finished wood
 Glass
 Enamel
 Plastic

 Paper (except newspaper)

 Metal
Rough surfaces collect contaminants that can be transferred to the interior of the

mouse by the ball. The surface you use should be free from spills, dirt, dust, lint,
wax, eraser dust, and other foreign matter. Rough surfaces can also cause the pads
located on the bottom of the mouse to prematurely wear. A deeply pitted surface
could cause erratic operation of the mouse.

 Inspect the work surface for spills or other contaminants.
 Dust the work surface.
 If you are using a paper pad, inspect it for wear and replace it if necessary.

General Information for 8-mm Tape Drive

Recommendations

 Use only Data Grade 8-mm tape cartridges. These cartridges are identified by

either a Data, D, or D8 marking on the data cartridge. Use of video grade
cartridges can damage the 8-mm tape drive and can void the warranty of your
8-mm tape drive, and data written on these tapes may be lost over a short period
of time.

 Remove the tape cartridge from the tape drive when it is not in use, and store

the cartridge in the cartridge case.

 Do not open the door on the data tape cartridge. This door covers and protects

the magnetic tape material from dirt, dust, and damage.

 Avoid touching the tape since this can cause loss of data.
 Keep the tape drive door closed except when loading or unloading a tape

cartridge.

 Back up and then discard any tape cartridge that repeatedly produces error

messages. The error information is in the system error log.

 Clean the tape path regularly according to the cleaning procedure of the 8-mm

tape drive. Use only recommended cleaning cartridges; other cleaning cartridges
can permanently damage your 8-mm tape drive.

Attention: Do not use video grade cartridges in the 8-mm tape drive. Video grade
tapes may be unreliable and may cause permanent damage to the 8-mm tape drive.

Types of 8-mm Tape Cartridges

 Test Tape Cartridge: This is a specially labeled tape cartridge that is in the

media kit with the 8-mm tape drive. Use this cartridge only when checking the
operation of the drive or running diagnostics; do not use it to save programs or
data.

 Data Tape Cartridge: This is a non-labeled blank tape cartridge that is in the

media kit. Use this cartridge for saving your programs or data. The same data
tape cartridge can be used in either a 2.3GB 8-mm tape drive or a 5.0GB 8-mm
tape drive.

 Cleaning Tape Cartridge: Use this cartridge for cleaning the 8-mm tape path. For

more information, see “Cleaning the Tape Path on the 5.0GB 8-mm Tape Drive”
on page 2-29.

IBM RS/6000 7025 F50 Series User's Guide

Tape Cartridge Compatibility

The 8-mm tape drive is compatible with existing 8-mm tape subsystems that comply
to the American National Standard (ANSI) X3B5/89-136, Helical-scan Digital
Computer Tape Cartridge, 8-mm for Information Exchange. Data compression
effectively increases the cartridge capacity and data transfer rate for the 5.0GB tape
cartridges.

Note: 160 meter cartridges are not processed and are automatically ejected by the
drive.

Setting the Write-Protect Tab on 8-mm Tape Cartridges

Setting the write-protect tab on a tape cartridge is necessary so that information is
not accidentally lost. When the write-protect tab of a tape cartridge is set (window
closed), information can be read from the tape, but cannot be written to it.

The window on the tape cartridge controls write-protection.

Chapter 2. Using the System Unit 2-21

Environment Considerations for 8-mm Data Cartridges

Information in this section describes operating and storage conditions including
temperature, relative humidity, and maximum wet bulb data.

Attention: The manufacturer has specified a set of temperature and humidity
ranges in which the 8-mm data cartridge can operate with ease. Only regular
cleaning procedures are required when operating the cartridge within this range. The
risk of possible data loss is increased if 8-mm tape cartridges are operated, stored,
or shipped outside the temperature or humidity ranges shown in the following table.

Before using a cartridge, always let it adjust (acclimate) to the operating
environment. Do this by placing the cartridge with its container in the operating
environment for as long as it has been away from this environment or for 24 hours,
whichever is less.

Acclimation is necessary for any data cartridge that has been exposed to a different
humidity environment or a temperature change of 11°C or 20°F or more.

2-22 IBM RS/6000 7025 F50 Series User's Guide

Operating in Harsh Environments

The 8-mm tape drive is ideally suited to streaming operations, as opposed to tape
movement operations involving multiple stop/starts and random searches. When the
tape is used for frequent stop and start operations, streaming movement is beneficial
and should be used whenever possible. This can be accomplished by ensuring that
any save or restore operation is the only active operation performed by a device
connected to this SCSI I/O controller.

Any tape that has been used outside the ranges specified in the table on 2-22 for an
extended period of time (50 passes in 40 hours of nonstop operation) should not be
used as an archival tape. Exposure to the environment will deteriorate the magnetic
and physical strength of the tape. Do not store important data on a tape that has
been used outside the specified ranges; transfer the data to a new tape for reliable
archiving.

8-mm Data Cartridge Erasure

Most bulk eraser devices do not have the capability to erase 8-mm data cartridges.
To properly erase an 8-mm data cartridge with a bulk eraser device, the erasure
rating must be at least 1500 oersted.

The 2.3GB and the 5.0GB 8-mm tape drives erase residual data before writing new
data on the data tape.

Tape Cartridge Data Efficiency

The 8-mm tape cartridge efficiency is defined as the amount of data that can be
stored on the cartridge. The following variables affect the amount of data that can be
stored on a tape cartridge:

 Size of the data file
 Number of file marks per file
 File mark size used
 Compatibility mode (2.3GB or 5.0GB)

 Media rewrites.

and the window side of the cartridge facing to the right.

2. Slide the tape cartridge into the opening on the front of the 8-mm tape drive until
the loading mechanism pulls the cartridge into the drive and the drive door
closes. The ready status light (green) goes on if the load operation was
successful.

The 8-mm tape drive is ready for data operations when the tape cartridge is inserted.
After the cartridge is inserted into the tape drive, the tape takes about 25 seconds to
load; this does not interfere with beginning the data operations.

2-26

IBM RS/6000 7025 F50 Series User's Guide

Commands can be entered while the tape is loading. Any commands to the tape
drive start running once the tape has finished loading. Commands not requiring the
tape cartridge are run immediately.

Chapter 2. Using the System Unit 2-27

Unloading the 8-mm Tape Cartridge

Before performing the unload operation, make sure the power to the 8-mm tape drive
is on.

To unload and eject the tape cartridge, press the unload button. The 8-mm tape
drive rewinds the tape and then ejects the tape cartridge from the tape drive.

After pressing the unload button, the following occurs:

1. The ready status light goes off.

2. The busy status light flashes during the unload operation.

3. The busy status light will goes off when the cartridge is ejected from the tape
drive.

2-28 IBM RS/6000 7025 F50 Series User's Guide

The time required for a tape to rewind and unload is between 18 seconds and 3
minutes, depending on the position of the tape when the unload button is pushed.

If the tape cartridge cannot unload and has to be removed manually from the drive,
contact your service representative.

Cleaning the Tape Path on the 5.0GB 8-mm Tape Drive

Attention: Do not use video cleaning cartridges in the 8-mm tape drive. Video

cleaning cartridges can damage the 8-mm tape drive.
The 8-mm tape path should be cleaned either approximately every 30 hours of tape

motion or once a month, whichever occurs first. The 5.0GB 8-mm tape drive counts
the number of hours of tape motion and indicates when the tape path requires
cleaning when the lighted disturbance status light (amber) is on.

More frequent cleaning may be required if the drive is operated in a dusty
environment or in humid conditions. If the dust is allowed to accumulate, the drive
has to perform more reads and writes. This can cause data loss, and may be
prevented by regularly scheduled cleaning of the drive.

The cleaning cartridge cleans the 8-mm tape drive. If you attempt to use an 8-mm
cleaning cartridge more times than allowed, the tape drive automatically detects the
error and ejects the cleaning cartridge. The disturbance status light (amber) remains
on if it was on prior to the cleaning operation being attempted.

Some video cleaning cartridges are extremely abrasive. An 8-mm tape drive may be
permanently damaged after only a few cleaning operations using an abrasive-type
cleaning cartridge.

Before loading the cleaning cartridge, make sure the power to the 8-mm tape drive is
on.

To load the 8-mm cleaning cartridge, do the following:

1. Grasp the edges of the 8-mm cleaning cartridge with the window side of the
cartridge facing to the right.

2. Slide the cleaning cartridge into the opening on the front of the 8-mm tape drive
until the loading mechanism pulls the cartridge into the drive.

Chapter 2. Using the System Unit 2-29

After the 8-mm cleaning cartridge has been fully inserted into the 8-mm tape drive,
the following cleaning operations are performed automatically:

1. The cleaning tape is loaded into the tape path.

2. The drive is cleaned by moving the cleaning tape forward for approximately two
minutes.

3. The tape is unloaded and the cleaning cartridge is ejected from the tape drive
when the cleaning operation is complete.

4. A successful cleaning operation is indicated when the disturbance status light
(amber) goes off.

The 4-mm tape drive uses a 4-mm data cartridge for saving and restoring your
system data. The 4-mm tape drive writes and reads only 4-mm Digital Data Storage
(DDS|||| or DDS2) cartridges.

Chapter 2. Using the System Unit 2-31

Recommendations

Attention: Tape cartridges that do not carry the proper DDS symbol cannot be

written to and their use may cause the 4-mm tape drive to report an error.

 Use only 4-mm Digital Data Storage (DDS|||| or DDS2) cartridges.

Attention: Use of other than recommended cleaning cartridges can damage
your tape drive and will void the drive warranty.

 Clean the tape path by using the recommended cleaning cartridge. Follow the

instructions on the cartridge.

 Back up and then discard any tape cartridge that repeatedly produces error

messages. The error information is in the system error log.

 Do not open the door on the data cartridge that covers the tape. This door

protects the magnetic tape material from dirt, dust, and damage.

 Do not operate in a dusty environment.
 Do not touch the tape material. Any substance transferred to the tape by

touching it could cause loss of data.

Types of 4-mm Tape Cartridges

The 4-mm tape drive is shipped with three 4-mm cartridges to help start your tape
operations immediately.

4-mm Data Cartridge: Use this non-labeled cartridge for saving or

restoring your programs or data. Additional data
cartridges can be ordered.

4-mm Diagnostic Cartridge: Use this specially labeled cartridge to perform

diagnostics on the drive. Do not use it to save or
restore programs or data.

Cleaning Cartridge: Use this cartridge for cleaning the 4-mm tape path.

For more information, see “Cleaning the Tape Path
on the 4.0GB 4-mm Tape Drive” on page 2-41.

IBM RS/6000 7025 F50 Series User's Guide

Tape Cartridge Compatibility

The 4-mm Tape Drive is compatible with existing 4mm tape subsystems that are
designed to operate with Digital Data Storage approved media, which meet the
following standards:

 For DDS||||

– American National Standard (ANSI) standard, X3.203-191, Helical-scan

Digital Computer Tape Cartridge, 3.81mm.

– European Computer Manufacturers Association (EMCA) standard,

EMCA-150 , 3.81mm Wide Magnetic Tape Cartridge and DDS|||| format.

 For DDS2

– European Computer Manufacturers Association (EMCA) standard,

EMCA/TC17/93/20, 3.81mm Wide Magnetic Tape Cartridge for Information
Interchange Helical Scan Recording, DDS2 format.

You cannot change the density setting of the drive, because the device reconfigures
itself automatically, depending on the media type installed, as follows:

Media Type Device Configuration
Non-DDS Read-only
DDS|||| Read/write in 2.0GB mode only.
DDS2 Read in either density; write in 4.0GB mode only.

Chapter 2. Using the System Unit 2-33

Setting the Write-Protect Tab on 4-mm Tape Cartridges

The window on the tape cartridge controls write-protection. When the write-protect
tab of a tape cartridge is set (window open), information can be read from the tape,
but cannot be written to it. When the write-protect tab of a tape cartridge is not set
(window closed), information can be both written to and read from the tape. Trying to
write to a 4-mm data cartridge with the window open causes an error.

2-34 IBM RS/6000 7025 F50 Series User's Guide

Environmental Considerations for 4-mm Data Cartridges

Information in this section describes operating and storage conditions including
temperature, relative humidity, and maximum wet bulb data.

Attention: The manufacturer has specified a set of temperature and humidity
ranges in which the 4-mm data cartridge can operate with ease. Only regular
cleaning procedures, as described in “Cleaning the Tape Path on the 4.0GB 4-mm
Tape Drive” on page 2-41 are required when operating the cartridge within this
range. The risk of possible data loss is increased if 4-mm tape cartridges are
operated, stored, or shipped outside the temperature or humidity ranges shown in
the following table.

Before using a cartridge, always let it adjust (acclimate) to the operating
environment. Do this by placing the cartridge with its container in the operating
environment for as long as it has been away from this environment or for 24 hours,
whichever is less.

Acclimation is necessary for any data cartridge that has been exposed to a different
humidity environment or a temperature change of 11°C or 20°F or more.

Operating Ranges Storage Shipping

Chapter 2. Using the System Unit 2-35

Operating in Harsh Environments

The 4-mm tape drive is ideally suited to streaming operations, as opposed to tape
movement operations involving multiple stop/starts and random searches. When the
tape is used for frequent stop and start operations, streaming movement is beneficial
and should be used whenever possible. This can be accomplished by ensuring that
any save or restore operation is the only active operation performed by a device
connected to this SCSI I/O controller.

Any tape that has been used outside the ranges specified in the previous table for an
extended period of time (50 passes in 40 hours of nonstop operation) should not be
used as an archival tape. Exposure to the environment will deteriorate the magnetic
and physical strength of the tape. Do not store important data on a tape that has
been used outside the specified ranges; transfer the data to a new tape for reliable
archiving.

4-mm Data Cartridge Erasure

Most bulk eraser devices do not have the capability to erase 4-mm data cartridges.
To properly erase an 4-mm data cartridge with a bulk eraser device, the erasure
rating must be at least 2000 oersted.

The 4-mm tape drive erases residual data before writing new data on the data tape.

Tape Cartridge Data Capacity

The 4-mm tape cartridge capacity is defined as the amount of data that can be
stored on the cartridge. The following variables affect the amount of data that can be
stored on a tape cartridge:

 Size of the data file
 Number of file marks per file
 Compatibility mode (2GB or 4GB)

 Media rewrites.

Loading the 4-mm Tape Cartridge

Before loading the tape cartridge, make sure the power is on and the write-protect
switch on the tape cartridge is properly set. Refer to “Setting the Write-Protect Tab
on 4-mm Tape Cartridges” on page 2-34. The tape drive loads the tape from the
cartridge and prepares it for reading and writing.

To load the 4-mm tape cartridge, do the following:

1. Grasp the edges of the 4-mm tape cartridge with the write-protect tab towards
you and the window side of the cartridge facing up.

2. Slide the tape cartridge into the opening on the front of the 4-mm tape drive until
the loading mechanism pulls the cartridge into the drive and the drive door
closes. The ready status light (green) goes on if the load operation was
successful.

The 4-mm tape drive is ready for data operations when the tape cartridge is inserted.
After the cartridge is inserted into the tape drive, the tape takes about 15 seconds to
load.

Chapter 2. Using the System Unit 2-39

Unloading the 4-mm Tape Cartridge

Before performing the unload operation, make sure the power to the 4-mm tape drive
is on.

To unload and eject the tape cartridge, press the unload button. The 4-mm tape
drive rewinds the tape and then ejects the tape cartridge from the tape drive.

After pressing the unload button, the following occurs:

1. The Read-Write status light flashes during the unload operation.

2. The Ready status light and the Read-Write status light turns off when the
cartridge is ejected from the tape drive.

The time required for a tape to rewind and unload is between 10 seconds and 1.5
minutes, depending on the position of the tape when the unload button is pushed.

If the tape cartridge cannot unload and has to be removed manually from the drive,
contact your service representative.

2-40 IBM RS/6000 7025 F50 Series User's Guide

Cleaning the Tape Path on the 4.0GB 4-mm Tape Drive

The 4-mm tape path should be cleaned either approximately every 30 hours of tape
motion or once a month, whichever occurs first. The 4-mm tape drive monitors the
recording quality of the tape cartridge and indicates that the tape path requires
cleaning when the disturbance status light (amber) is on.

More frequent cleaning may be required if the drive is operated in a dusty
environment or in humid conditions. If the dust is allowed to accumulate, the drive
has to perform more reads and writes. This can cause data loss, and may be
prevented by regularly scheduled cleaning of the drive.

The cleaning cartridge cleans the 4-mm tape drive 50 times before it needs to be
discarded. If you attempt to use a 4-mm cleaning cartridge more than 50 times, the
tape drive automatically detects the error and ejects the cleaning cartridge with the
disturbance status light (amber) remaining on.

Before loading the cleaning cartridge, make sure the power to the 4-mm tape drive is
on.

To load the 4-mm cleaning cartridge, do the following:

1. Grasp the edges of the 4-mm cleaning cartridge with the window side of the
cartridge facing up.

2. Slide the cleaning cartridge into the opening on the front of the 4-mm tape drive
until the loading mechanism pulls the cartridge into the drive.

After the 4-mm cleaning cartridge has been fully inserted into the 4-mm tape drive,
the following cleaning operations are performed automatically:

1. The cleaning tape is loaded into the tape path.

Chapter 2. Using the System Unit 2-41

2. The drive is cleaned by moving the cleaning tape forward for approximately 30
seconds.

3. The tape is unloaded and the cleaning cartridge is ejected from the tape drive
when the cleaning operation is complete.

4. A successful cleaning operation is indicated when the disturbance status light
(amber) goes off (if it was activated before the cleaning operation).

If the cleaning cartridge has been used more than 50 times the disturbance status
light (Amber) will flash.

The Select Software option, if supported by the operating system, shows the names
of the operating system installed. This option may not be supported by all operating
systems.

In the case of AIX this is a supported option, if you receive a message saying that:

No Operating System Installed

this would mean that information in non-volatile storage could have been lost, as
would happen if the battery had been removed. In order to recreate this value issue
the bootlist command under AIX with the appropriate parameters as to the location of
the operating system in a particular Hard disk. Please see the explanation of the
bootlist command in your AIX documentation.

The Software Default option, if supported by the operating system, lets you select the
default operating system to start the system. This option may not be supported by
all operating systems.

The Install From option produces a list of devices, for example the CD-ROM, where
the operating system is installed from. You select one of the devices and the system
searches the device for an operating system to install and if supported by the
operating system in that device, the name of the operating system displays.

The Select Boot Device option provides a list of devices that can be selected to be
stored on the boot list. Up to 5 devices are supported.
