- Please read this chapter -
The information required to use the Built-In AITAuto-Loader Unit correctly is described below.
Safety Considerations
To use the Built-In AIT Auto-Loader Unit safely, please read the considerations listed in this
section and fully understand them. For explanations on the symbols, refer to “Safety Indications”
described at the beginning of this manual.
Important
See the instruction manual provided with the basic processing unit on which the N8551-29F Built-
In AIT Auto-Loader Unit is mounted, in addition to the considerations given herein. The basic
processing unit instruction manual describes the precautions to be taken during mounting/
dismounting the options.
WARNING
■Do not disassemble or modify the Built-In AIT Auto-Loader Unit.
Do not disassemble or modify the N8551-29F Built-In AIT Auto-Loader Unit.
If you do so, a fire or you may receive an electric shock.
■Do not use the Built-In AIT Auto-Loader Unit if it emits smoke or a bad, odor
or makes an abnormal noise.
If smoke, odor or abnormal noise is detected, immediately turn off the basic
processing unit and unplug the power cable from the AC outlet. Then, contact
your dealer or the NEC maintenance service company. If a faulty unit is used
continuously, it may cause a fire.
■Do not use the damaged Built-In AIT Auto-Loader Unit continuously.
If the N8551-29F Built-In AIT Auto-Loader Unit is damaged, immediately
turn off the basic processing unit and unplug the power cable from the AC
outlet. Then, contact your dealer or the NEC maintenance service company.
Using such a faulty unit continuously may cause a fire.

v
WARNING
■Do not insert a wire or a metal chip into the Built-In AIT Auto-Loader Unit.
Do not insert a foreign material such as a metal chip or wire into the ventila-
tion port or the cartridge slot, as this may cause an electric shock.
■Do not use the Built-In AIT Auto-Loader Unit at an unsuitable site.
Refer to the instruction manual provided with the basic processing unit and
check that the Built-In AIT Auto-Loader Unit is installed at a suitable site.
Otherwise, a fire and electric shock as well as operational malfunction may be
caused.
■Do not touch the driver with wet hands.
Do not mount/dismount the Built-In AIT Auto-Loader Unit with wet hands, as
this may cause an electric shock.
CAUTION
■Connect the cable correctly.
Connect the cable as explained in "Mounting on the basic processing unit" on
page 7 of this manual.
■Do not bend the cable.
Do not bend, twist, or bind the power and connection cables. Also, do not put
a load on the cable or catch the cable between things. The cable could be
damaged, and this may cause a fire or electric shock.
■Do not connect or disconnect the cable without removing the plug
When connecting or installing the basic processing unit and peripheral
devices, make sure you unplug the power cord that is connected to the basic
processing unit. To avoid electric shock, do not connect or disconnect the
cable while the power cord is plugged in.
■Do not used damaged cables
Before connecting cables, check that the connector is not damaged, the
connector pins are not bent, and that the connector is not dirty. If the connec-
tor is damaged, the pins are bent, or the connector is dirty, the connector may
short and cause a fire.

vi
CAUTION
■Plug-in the connector up to the end.
Plug-in the cable connector firmly up to the end. If you plug-in the connector
halfway, the poor contact causes the Built-In AIT Auto-Loader Unit to be
heated up and may result in a fire. If dust collects on the outlet, it may be
heated when it comes in contact with water drops and cause a fire.
■Do not hold the cable when unplugging it.
Hold the connector head when plugging or unplugging the power cable and
connection cables. The cable may be damaged if it is pulled, which may cause
a fire or electric shock.
■Do not short circuit the connector pins.
This may cause a fire or electric shock.
■Do not mount the Built-In AIT Auto-Loader Unit on a unit other than the
specified one.
If you mount it on an unauthorized unit, a malfunction, fire and electric shock
may be caused.
■Do not block the fan.
Do not block the fan on the rear of the Built-InAIT Auto-Loader Unit. The
inner temperature will rise and may cause a malfunction, fire and electric
shock.
■Do not put water or foreign materials in the Built-In AIT Auto-Loader Unit.
Do not put water/other liquids or foreign materials such as pins and clips in
the Built-In AIT Auto-Loader Unit. This may cause a fire, electric shock or
failure. If such an object is inserted by mistake into the Built-In AIT Auto-
Loader Unit, immediately turn off the power and unplug the power cable from
the outlet. Leave the Built-InAIT Auto-Loader Unit as it is (do not disassem-
ble it) and contact your dealer or the NEC maintenance service company.
■Do not touch the Built-In AIT Auto-Loader Unit during lightning.
If lightning is likely to occur, unplug the power cable from the outlet. If
lightning starts before you have unplugged the power cable, do not touch the
entire unit including the cables. Otherwise, a fire or electric shock may be
caused.

vii
CAUTION
■Do not store the Built-In AIT Auto-Loader Unit in a dusty, humid place.
Do not store the Built-In AIT Auto-Loader Unit in a humid place, for example,
near a hot water supply. If you reinstall the Built-In AIT Auto-Loader Unit, a
fire may be caused.
■Do not use cellular phones or pagers near the unit
Do not use cellular phones or pagers near this unit. Doing so may cause a
machine malfunction.

• If the magazine write protect plug is set to Write Disabled, data cannot accidentally be written to
the data cartridges inserted in the magazine. (Even if the data cartridge write protect plug is set
to Write Enabled, data cannot be written to the data cartridge if the magazine’s write protect
plug is set to Write Disabled.)
REC
• It is recommended that you should label the magazine so that you can check the contents of the
data cartridge set in the magazine.
• Use the magazine specially designed for the N8551-29F Built-In AIT Auto-Loader Unit.

Built-In AIT Auto-Loader Unit 1
Built-In AIT Auto-Loader Unit
This chapter explains setup, installation and daily operation of the N8551-29F Built-InAIT Auto-
Loader Unit.
Features
This unit has the following features:
• You can record large amounts of data on the AIT1 and AIT2 data cartridges using AIT (Ad-
vanced Intelligent Tape) format.
• When using the data compression function*1, you can record 50 to 100 GB of data on the AIT2
Data Cartridge, and 25 to 50 GB of data on the AIT1 Data Cartridge.
• The basic processing unit automatically determines whether data recorded on the AIT data
cartridges is compressed. It can also read data recorded on AIT data cartridges with conven-
tional AIT drives.
*1 The compression rate for recorded data may differ depending on the user environment and
the type of data.
(100 GB can be recorded when using twice the average compression rate (for AIT2 data
cartridges).)
Usable Cartridges
Please use Sony AIT data cartridges (AIT2 (tape length: 230 m), or AIT1 (tape length: 170 m))
with this unit. Using other types of AIT data cartridges may cause read and write errors.
