Safety Notes
This section provides several precautions to enable you to use the product safely and correctly and to prevent injury
and property damage. Read this section carefully to ensure proper and safe use of the product. For symbols, see
"SAFETY INDICATIONS" provided earlier.
General Attention
Do not use in life-critical applications or applications requiring high reliability.
This device is not intended for integration with or control of facilities or equipment
that may affect human life or that require a high degree of reliability, such as
medical equipment, nuclear power facilities, aerospace instruments, and
transportation equipment. The manufacturer does not assume any liability for
accidents resulting in injury or death, or for any damages to property that may occur
as a result of using this device in such facilities, equipment, or control systems.
Do not use the Internal LTO if any smoke, odor, or noise is present.
If smoke, odor, or noise is present, immediately turn off the POWER switch and
disconnect the power plug from the outlet, then contact your sales agent. Using the
Internal LTO in such conditions may cause a fire.
Keep needles or metal objects away from the Internal LTO.
Do not insert needles or metal objects into ventilation holes in the Internal LTO.
Failure to follow this warning may cause an electric shock.
Keep water or foreign matter away from the Internal LTO.
Do not let any kind of liquid (water etc.) or foreign matter (e.g., pins or paper clips)
enter the Internal LTO. Failure to follow this warning may cause an electric shock, a
fire, or a failure of the Internal LTO. When such things accidentally enter the Internal
LTO, immediately turn off the power and disconnect the power plug from the outlet.
Do not disassemble the Internal LTO. Contact your sales agent.

6
Attention to Power or Power Cord
Do not hold the DC cable with a wet hand.
Do not disconnect/connect the cable while your hands are wet. Failure to follow this
warning may cause an electric shock.
Do not install the device while the power is turned on.
Unplug the AC power cord from the main power source when installing/uninstalling
the device to/from server or connect it with the enclosure. Failure to follow this
warning may cause an electric shock.
Insert the DC cable into the outlet as far as it goes.
Heat generation resulting from a halfway inserted DC cable (imperfect contact) may
cause a fire. Heat will also be generated if condensation is formed on dusty blades
of the halfway inserted cable, increasing the possibility of a fire.
Do not connect the Internal LTO by unspecified cabling.
Connecting or cabling with DC cable should be done in accordance with the
procedure specified in the User's Guide.
Unspecified connecting or cabling may cause an electric shock or a fire.
Do not use any damaged power cord.
If the power cord is damaged, immediately replace it with a new part of same type.
Do not repair the damaged section for reuse. Otherwise, the section repaired with
vinyl tape or the like will be overheated to cause an electric shock or a fire.
Use the authorized cable only.
Use only the specified cable when connecting the Internal LTO with a server. Use of
an unspecified cable or connection by unspecified cabling may cause a fire.

7
Attention to Installing, Moving, Storing, Connection
Do not close the ventilation hole.
Do not close the ventilation hole in the front side of the Internal LTO. Otherwise, its
internal temperature will rise to cause malfunctions or a fire.
Do not connect/disconnect the interface cables before unplugging the power
plug.
Before connecting/disconnecting the interface cables, disconnect the power plug of
the main power unit from the outlet. If the power is off but the power plug is still
connected, you may get an electric shock.
Do not use the unspecified interface cables.
Uses only the cable authorized by NEC and locate the device and connector before
connection. Use of an unauthorized cable or displaced connection may cause a
short circuit, resulting in a fire.
When handling or connecting the interface cables, keep the notes as follows:
Do not tread on cables.
Do not load on the cable.
Insert the cable connector as far as it goes.
Do not use damaged cables.
Do not use damaged connectors.
Do not use or keep in the environment where corrosive gas exists.
Do not use Internal LTO, installing in the environment where corrosive gas (sulfur
dioxide, hydrogen sulfide, nitrogen dioxide, chlorine, ammonia, ozone, etc.) exists.
In addition, do not set it up in the environment including the element (sodium
chloride and sulfur, etc.) that promotes corrosion in dust and air, and the
electro-conductive metal etc. The print plate in the device corrodes, and it might
cause the breakdown and smoking and the ignition.
When there is the above-mentioned doubt in the environment of use, please consult
with a store or a maintenance service company.
Avoid installation in extreme temperature condition.
Immediately after the power supply of the server is turned off, components in the
server including the internal hard disk drive or others are hot. Please install/detach
the device after confirming it is cold enough.

other than described in this User's Guide. Failure to follow this instruction may
cause an electric shock or a fire as well as malfunctions of the Internal LTO.
The following can be performed by the Internal LTO user. Do not perform any other
type of disassembly than described here.
Remove or install latching rails
Remove or install the SAS cable
Do not handle while the power plug is connected.
Before handling or cleaning the Internal LTO, disconnect the power plug of the main
power unit from the outlet. If the power is off but the power plug is still connected,
you may get an electric shock.
Insert the cables into the connectors as far as it goes.
Heat generation resulting from a halfway inserted cables or Interface cables
(imperfect contact) may cause a fire. Heat will also be generated if condensation is

For Proper Operation
To operate the Internal LTO correctly, observe the following points.
For considerations on handling the data cartridge, refer to the chapter "Data Cartridges".
 Do not turn off the server when the LED on the front of the Internal LTO is blinking.
→This may cause a machine failure or damage of backup data.
 Do not store the Internal LTO in a place subject to corrosive gas, chemicals, or splash of chemicals.
→Internal LTO parts may be deformed or damaged and may not be able to operate correctly.
 Do not store the Internal LTO in a place subject to strong vibrations.
→This may cause the Internal LTO to be defected.
 As the data cartridge set in the Internal LTO, use our "Data Cartridges.
→If you use a data cartridge of other manufacturer, a read/write error may occur.
 Any data cartridge cannot be used as the system disk.
→This may cause the OS to be started unsuccessfully and/or the data in the data cartridge to be broken.
 Do not disassemble data cartridges.
→This may cause the data stored in the data cartridge to be broken. Inserting a data cartridge having
been disassembled into the Internal LTO may cause the Internal LTO to be defected.
 Do not bring a substance which generates magnetism close to data cartridges.
→This cause the data stored in the data cartridges may be broken.
Installing or Uninstalling an Internal Optional Device
1. Notes before carrying out the work
(1) To avoid electric hazard and malfunction, be sure to turn off the Power switch of this product and
unplug the power cord from an outlet before carrying out the work. However, there is no need to do
this if the internal optional device is hot-swappable.
(2) This internal optional device consists of static-sensitive electronic components. To avoid failures
caused by static electricity when installing or uninstalling the internal optional device, wear an
anti-static wrist strap on your wrist and provide earthing before carrying out the work. And also
connect a wrist strap to earth ground when you wear a wrist strap.
(3) Handling of cables
When connecting a cable (e.g., LAN cable), static electricity may also be charged due to friction
against the floor. Connecting a charged cable with an I/O device may cause damage to the devices.
It is recommended to discharge static electricity before connecting a cable by using neutralization
apparatus and so on.
