vendors be used.

Data Compression

The AIT 35 LVD tape drive ships from the factory with data compression enabled
for writing. The drive is equipped with Adaptive Lossless Data Compression
(ALDC) algorithm. In this mode, data is always compressed when writing to the
tape, but the drive is capable of reading both compressed and uncompressed tapes.
For the drive to write uncompressed data, you must change the data compression
hardware setting. This can be changed by software or using the DIP switches.
Consult your backup application software documentation for the data compression
enabling and disabling procedure.

Compaq recommends that only tapes purchased from qualified

Loading and Unloading a Tape

Loading a Tape

Insert a tape into the slot on the front panel of the drive. As the tape is inserted, the
drive takes it and automatically loads it into the drive mechanism.

Unloading a Tape

The tape can be removed from the drive either via software or the eject button. By
pressing the eject button, the tape will rewind and the drive ejects the tape from the
slot.

Forcing the Ejection of a Tape

CAUTION:

also end up invalidly formatted, because End of Data (EOD) may not have been
written. Force an ejection only as a last resort; never use it as a quick way to
eject the tape.

By pressing the eject button when the drive is busy, it may take a while for the
drive to respond to the request, because the drive will finish the task it is engaged
in before it responds. This ensures that the task is terminated in a controlled
manner and no data is lost.

However, there may be occasions when unloading a tape is urgently needed, even
at the risk of losing data. Forcing the ejection of the tape must be performed. To do
this, hold the eject button down for at least 5 seconds. The tape is immediately
unthreaded and the tape is ejected, regardless of what operation the drive was
performing.

WARNING:

attempt to open this product. Refer all service to a Compaq Authorized Service
Provider.

You may lose data if you force the ejection of a tape. The tape may

Write-Protecting a Tape

The tape has a write-protect switch 2 to prevent accidental erasure of data. Before
loading the tape into the drive, position the write-protect switch on the front of the
tape. By moving the switch to the right, the tape is write-protected and by moving
the switch to the left, the tape is write-enabled.

Tape Handling and Storage

For longer life of recorded or unrecorded tapes, store tapes in a clean environment
with these conditions:

Keep the tape out of direct sunlight and away from heaters and other heat

■

sources.

Use the tape in temperatures between 15° C and 35° C (59°F to 95°F).

■

If the tape has been exposed to extreme heat or cold, stabilize it at room

■

temperature for the same amount of time it was exposed – up to 24 hours.

Do not place the tape near electromagnetic interference sources, such as

■

video monitors, motors, and video or X-ray equipment. Data on the tape can
be altered.

Store the tape in a dust-free environment where the relative humidity is

■

between 20% and 80%. For longer cartridge life, store the tape at 20% to
40% relative humidity.

Tape Drive Cleaning

Reliable backup of your system is the product of at least four components:

A reliable tape drive

■

Quality tape cassettes

■

Regular backup schedule with backup media stored offsite

■

Routine tape drive maintenance

■

Compaq tape drives are designed to operate reliably under worst case conditions;
however, they require simple routine maintenance to operate efficiently. Regular
cleaning is the most essential step in properly maintaining a tape drive and
preventing errors.

6

Reliability of Backup Devices

The reliability of any backup device is directly related to its duty cycle (the number
of hours per day that the device is in use). For example, if a tape drive designed for
1-GB backups is being used to back up a 10-GB computer, the result on that drive
will be premature aging and reliability problems.

6-2 Compaq AIT 35 LVD Tape Drive Reference Guide

Importance of Routine Cleaning

The tape drive has a cleaning roller built in which prevents and recovers from head
contamination. This feature minimizes buildup on the read/write heads so fewer
cleaning cycles with a cleaning tape are required. However, Compaq recommends
a routine cleaning schedule every 100 hours of use to keep the tape drive in good
working order. The drive will also need cleaning when the drive Status LED
displays long flashes with short pauses (See Table 5-2).

IMPORTANT:

Failure to follow recommended cleaning procedures could result in serious damage to the
tape drive.

Regular cleaning is vital to trouble-free operation of any tape device.

When a drive is cleaned according to a regular schedule, one cleaning cycle
typically removes accumulated dirt and particle deposits. However, in a dusty
environment, or if a regular cleaning routine has not been followed, one cleaning
cycle may not fully clean the AIT 35 LVD drive read/write heads.

Errors Resulting from Cleaning Neglect

Following are some of the errors that can result from failure to observe routine
maintenance and cleaning of tape drives:

■

Dropouts

Caused by weak signal strength from dirty read/write heads, a dropout can
result in reduced tape capacity and backup performance.

■

Media errors

The backup tapes can be jammed, torn, or otherwise damaged by a dirty
read/write head.

■

Read or write errors

Because of a dirty read/write head, data may not have been recorded on the
tape during backup. Even if the data is on the backup tape, retrieval may not
be possible if the dirty head cannot read the data.

■

Format failures

During backup, data is laid on the tape in a certain format for easy retrieval.
A dirty write head can cause format failures, which means that data can be
lost or impossible to retrieve.

■

Bad blocks

Because of media damage (see media errors above), the tape may not accept
backup data. Also, the read/write head may be unable to retrieve data from
bad blocks.

Importance of Compaq Approved Tapes

Compaq approved tapes are thoroughly tested to meet high-quality standards.
Before Compaq recommends a tape, the quality and reliability of the magnetic
media and the tape are evaluated. Do not use an unapproved tape as it may not be
compatible with Compaq tape drives.

The data tapes must meet these requirements:

Only Standard AIT 35 GB tapes, Advanced Metal Evaporate

■

Must be one of the following sizes: 170 m (557 ft) or 230 m (754 ft)

Federal Communications Commission Notice

Part 15 of the Federal Communications Commission (FCC) Rules and
Regulations has established Radio Frequency (RF) emission limits to provide
an interference-free radio frequency spectrum. Many electronic devices,
including computers, generate RF energy incidental to their intended function
and are, therefore, covered by these rules. These rules place computers and
related peripheral devices into two classes, A and B, depending upon their
intended installation. Class A devices are those that may reasonably be
expected to be installed in a business or commercial environment. Class B
devices are those that may reasonably be expected to be installed in a
residential environment (for example, personal computers). The FCC requires
devices in both classes to bear a label indicating the interference potential of
the device as well as additional operating instructions for the user.

The rating label on the device shows the classification (A or B) of the
equipment. Class B devices have an FCC logo or FCC ID on the label. Class A
devices do not have an FCC logo or ID on the label. After the class of the
device is determined, refer to the corresponding statement in the sections
below.

and used in accordance with the instructions, may cause harmful interference
to radio communications. Operation of this equipment in a residential area is
likely to cause harmful interference, in which case the user will be required to
correct the interference at personal expense.

Class B Equipment

This equipment has been tested and found to comply with the limits for a

Electrostatic Discharge

To prevent damaging the system, be aware of the precautions you need to follow
when setting up the system or handling parts. A discharge of static electricity from
a finger or other conductor may damage system boards or other static-sensitive
devices. This type of damage may reduce the life expectancy of the device.

To prevent electrostatic damage, observe the following precautions:

Avoid hand contact by transporting and storing products in static-safe

■

containers.

Keep electrostatic-sensitive parts in their containers until they arrive at

■

static-free workstations.

Place parts on a grounded surface before removing them from their

■

containers.

Avoid touching pins, leads, or circuitry.

■

Always make sure you are properly grounded when touching a

■

static-sensitive component or assembly.

B-2 Compaq AIT 35 LVD Tape Drive Reference Guide

Grounding Methods

There are several methods for grounding. Use one or more of the following
methods when handling or installing electrostatic-sensitive parts:

Use a wrist strap connected by a ground cord to a grounded workstation or

■

computer chassis. Wrist straps are flexible straps with a minimum of 1
megohm ± 10 percent resistance in the ground cords. To provide proper

ground, wear the strap snug against the skin.

Use heel straps, toe straps, or boot straps at standing workstations. Wear the

■

straps on both feet when standing on conductive floors or dissipating floor
mats.

Use conductive field service tools.

■

Use a portable field service kit with a folding static-dissipating

■

work mat.

If you do not have any of the suggested equipment for proper grounding, have an
Authorized Compaq Reseller install the part.

NOTE:

For more information on static electricity, or assistance with product installation,

contact your Authorized Compaq Reseller.
