User Guide and Instruction Manual
LG Network Storage

Note
1Do not place any objects within 15cm of the unit.
The unit reaches high temperatures creating the risk of burn injuries.
2Only use compatible devices with the system ports, or the system and devices risk
being damaged.
3 Do not use damaged disks. Product can be damaged.
4Do not dismantle or change the structure of the system in any way.
This may cause electric shock.
5
When dealing with system components, strictly abide by the instruction manual.
Physical contact with the soldering on the backside of components may cause
severe injury.
6
When transporting the system, rst turn o the system and disconnect the unit
from the power source. Sudden tension in cables can cause severe damage to the
system. Loose cables can cause injury.
7
Take caution when handling the system so as not to corrupt the hard disk data.
- Take caution not to bump or expose the system to extreme temperatures, as it
may damage the sensitive hard disk.
- Take caution when turning on the electricity, as during this time any external
bumps to the system may corrupt the hard disk data.
- The manufacturer disclaims all responsibility for loss of hard disk data.
Safety warning

Related to damage to the HDD and data:
- during installation or disconnection of the system, ensure that the system does
not experience any external physical shocks.
- During the operation of the HDD, short surges and stoppages of power may
cause the system to turn o and on quickly.
- there may be a sudden stoppage of electricity during operation
- avoid moving the system during operation of the HDD, which may cause
external physical shock
- during the conguration of new volumes.
i) if during use, existing volumes are deleted and new volumes are created, data
will be lost.
ii) Before conguration of new volumes, each user must back up data, as well as
when creating new volumes, to ensure the possibility of restoration.
– e.g. virus infections.
• Always back up hard disk data to avoid accidental data loss.
9
In the event of the administrator forgetting the password, restoration is
impossible. Hence safeguard the password.
• To create a new password, the system must be re-initialized. In this case, all
data will be lost, and data recovery will be impossible, for security reasons. The
manufacturer disclaims all responsibility in the event of this occurrence.
10 In the event of the cover being removed during operation, the user risks electric
shock, injury, and damage to the system.

Warning
1Do not use damaged electrical cords. This may cause electric shock, and is a re
hazard.
2Use a grounded cord and grounded socket to avoid electric shock and damage to
components.
3Do not handle the electrical cord with wet hands, as this may cause shock and
injury.
4When removing the plug from the socket, ensure that the plug is handled and not
the cord. Otherwise this may cause damage to the plug and even re.
5Always check and use correct voltage to avoid electric shock, severe damage to
the system, and re.
6Always use grounded cords and grounded sockets with correct capacity (voltage /
current) to avoid the danger of damage, electric shock, and injury.
7In the event of noise emanating from the electrical cords or sockets, to avoid re
and injury immediately disconnect, and contact the service centre.
8 Ensure that electrical cords are correctly plugged into the sockets to avoid re.
9
Ensure that electrical cords are not damaged or do not have heavy objects placed
on them. Keep electrical cords away from children and pets. Damaged cords may
cause electrical shock or re.
10 Keep the power cords and sockets clean at all times to avoid re and electrical
shock.
11
In the event of moisture entering the system, immediately disconnect the power
and contact the service centre, to avoid the danger of system damage, electrical
shock, and re.
12 Do not block vents, as this will cause system damage.
13 Prior to cleaning the system, always disconnect the power, to avoid damage and
electric shock.

14 In the event of lighting and thunderstorms, immediately physically disconnect the
system from any power source, to avoid damage to the system.
15 In the event of dropping the system, contact the service centre for advice and
possible service. Not doing this creates the risk of damage, re and electric shock.
16 Keep the system away from direct sunlight to avoid overheating, and melting of
the case, which may eventuate in re and injury.
17 Do not place ammable objects, candles or cigarettes on the system, as this may
cause re
18 In the event of a burning smell or smoke emanating from the system, immediately
disconnect the power, and contact the service centre.
19
Keep heating devices and other electrical components at a distance from the
system to avoid case melting, and hence the danger of damage, re, and electric
shock.
20 Before disassembling the system, always ensure physical disconnection of the
electrical cable from the socket.
21 Do not disassemble the power supply, to avoid the danger of electric shock.
22
Keep children away from the system, as consuming any parts will cause serious
injury.
In the event of swallowing any parts, such as screws, immediately seek medical
treatment.
23
Ensure that multipoint power sockets are not overloaded, to avoid the danger
of re and electric shock. Ensure that cords are always neatly arranged and are
not trapped under the system or other heavy objects. When connecting and
disconnecting the electrical cord, take care in handling the socket to avoid the
danger of electric shock.
24 Ensure that there are no loose or exposed metallic objects inside the case, to avoid
the danger of damage, re and electric shock.
25 Ensure that hands are never used, to avoid damaging the system and electric
shock. Always use screw drivers for work inside the system.

Hard disk installation and set up
The LG NETWORK STORAGE hard disk rack is shown below. Refer to each part while
installing the HDDs.
Components of Hard Disk Rack
Safety Lever
Locker Lever Hard Disk Rack Lever
Hard Disk Rack
Hard Disk Rack Label No.
Note: Hard disks of size 500GB/1TB/2TB are recommended, all of which should
be the same size and of the same company. If the disk sizes dier, the RAID
conguration will use the smallest disk as a reference to measure all disk
sizes,therefore the remainder can not be utilized and durability decreases.
