Introduction
What is NAS?
NAS is short for “Network attached Storage”, which is used to name a specialized device
that offers mass storage towards a data network. SOHO NAS like the ICY BOX IB-
NAS2001 are small devices that simply share data from HDDs to an Ethernet. There are
many approaches; some are using custom shaped methods in offering the storage space
to the network participants. This approach needs special software to be installed on the
network clients and in most cases is limited to one particular operating system.
The ICY BOX IB-NAS2001 has chosen to offer the HDD space in the way common
operating systems are expecting it. This means it uses the same principles (protocols) to
offer HDD-Storage as common file servers are doing it but with less noise, lower power
consumption and in a much simpler way. The main advantage is that, that special
software is unnecessary to access the storage provided, whilst maintaining the maximum
security features, as already offered within the operation system, such as user and group
based access control.
Samba (Windows)
Netzwerk
The samba server implemented in the ICY BOX IB-NAS2001 offers storage in a way
regular Windows shares are doing it (commonly known as SMB or CIFS protocol). Even
Operating systems like MAC OS and Linux are capable of using this kind of network
storage access. It provides a maximum of security by offering the opportunity to limit the
access on users or groups.
4

FTP
Netzwerk
Router
The FTP protocol is one of the oldest ways for file transfer in the internet. It is fast and
could easily be used to access the HDD even via the internet. A huge set of different
software clients exists even for exotic operating systems using this simple but fast
protocol. Most internet access routers used in small offices and at home offer a
mechanism called port forwarding (virtual server, etc.) which could be easily used to
expose the ICY BOX IB-NAS2001’s storage to the internet. The FTP protocol offers access
control based on user and groups.
NFS
In the Unix world the NFS protocol is common to share disk space via network. This
protocol could be used to mount natively network storage to all kinds of Unix operating
systems like Linux, Solaris, etc. The NFS protocol is fast but does not provide a User or
Group based access control server sided. Access control is limited to the definition of
singular or a set of IP-Addresses (host addresses).
More than a NAS
The ICY BOX IB-NAS2001 is not only an easy to use network storage device. It is a truly
double functional HDD box. It offers a complete USB 2.0 HDD access chipset, offering
greater flexibility. Users have the option of using it as a NAS where a network connection
is available or connect it via the much faster USB 2.0 Interface in the same way they do
it with a conventional external hard drive. This dual-functional design provides a
maximum of flexibility to access the data on the ICY BOX anytime anywhere.
USB

But the IB-NAS2001 is even more. You can print via Network or, if you like to distribute
Musik or Videos via your network at home, the UPnP-AV protocol can do this directly to
your network media player.
And if that still is not enough: The IB-NAS2001 can be additionally extended by other
Applications.
USB
Printserver
Netzwerk
Attach your printer to the IB-NAS2001 and use it via network from different computer
simultaneously.

UPnP-AV
Netzwerk
The included Twonky Media Server (30 days trial version) adapts this standard to as
many players as possible. The Twonky Media Server has been updated several times a
year so far to ensure compatibility to all new players. Therefore we have chosen to not
implement this software fix in the firmware of the IB-NAS2001 but to give the user to
easily upgrade it when a new version is released. A permanent license can be purchased
from the Website of Twonky Media by following a link from the user interface of Twonky
Media.
7

Bonjour and iTunes Support
Netzwerk
The IB-NAS2001 is able to assign its services via Bonjour, so that MAC computer can
easily be connected to the server functions of the IB-NAS2001. Due to the iTunes
support, multimedia files can be accessed via iTunes from anywhere in the network.
Extensibility
The IB-NAS2001 can arbitrarily extended on applications by installing additional software
packages. In contrast to the closed systems of other manufacturer, the IB-NAS2001 is
future-proof and open to new developments.

Usage as external Storage drive
First come first serve
To use the Icy Box IB-NAS2001 as an external storage enclosure all is required is to
connect to the USB interface of a computer. The decision whether the IB-NAS2001 is
operating as an external storage case or as a NAS is determined by the first come first
serve principle. After turning on the IB-NAS2001 the interface which is connected defines
the operation mode.
Attention: Do not connect the USB and the Network interface at the same time!
Once the IB-NAS2001 is connected to USB and power up it acts as a standard external
hard drive.
Attention: To make sure that the IB-NAS2001 operates appropriate as an
external hard drive and as a NAS it is necessary to initialize and
format the hard drive in the NAS modus as described in chapter
“Hard disk initialization” on page19. This is necessary because the
NAS modus needs 2 additional reserved partitions witch are created
during this procedure. To be able to write on that partition on a
Windows computer the chosen file system of the data partition has to be
FAT32.
11

12
If connected to a Windows system the first 2 Partitions created by the NAS setup process
are not visible because the are formatted with a file system windows is not able to use by
default.
Attention: The content of the first two system partitions created by the NAS setup
process must not be changed manually in order to guaranty the
appropriate operation of the IB-NAS2001 in the NAS modus.
To switch between the NAS modus and then external hard drive modus it is first
necessary to turn of the IB-NAS2001, disconnect the old interface, connect the new one
and turn it on again. After that the Modus is chosen in the described way by the first
interface witch is connected at the time of start up.
How to access the Management Interface
The NAS modus is controlled by a web based interface which could be accessed by using
a standard web browser. In a normal network environment this is simply done by
entering “http://icybox” in the address line of the web browser. But whether that works
is determined by the configuration of the network environment.
The following Possibilities are given:
DHCP controlled Network with automatic DNS update
In a DHCP1controlled Network the ICY BOX IB-NAS2001 is assigned with an IP Address2
by the DHCP server. In case the DHCP server updates this information automatically to
the DNS3Server (see RFC 2136). The ICY BOX IB-NAS2001 could be accessed by simply
entering “http://icybox” in the address line of a standard web browser. Continue with
point “Using the management interface” for setting up the IB-NAS2001 on Page 17.
1
DHCP acronym for “dynamic host configuration protocol” names a process witch assigns network parameters to a computer
attached towards a network automatically via a specialized DHCP server. Most DSL routers provide such a service.
2
IP-Address is a 32 bit binary number mostly expressed by a group of four numbers in the Range between 1 and 255
separated by “.” e.g. 169.254.100.100. This is used for addressing hosts in a TCP/IP based Network.
3
DNS is the acronym for “domain name service”. This names a process of assigning internet names to IP Addresses. The DNS
server is comparable to a telephone book. At this server all internet applications look up the referring IP Address for an internet
name. Without that service or when the DHCP server doesn’t know the internet name, the internet name could not be used to
address a host or device. The only chance to get access to that host or device is to use the IP Address directly.

DHCP controlled Network without automatic DNS update
In a DHCP controlled Network environment the IB-NAS2001 gets its IP Address from the
DHCP server. If the DHCP server does not update that information to the DNS server the
necessary name resolution for entering “http://icybox” will not work because the DNS
server has no information about the actual IP Address of the IB-NAS2001. To find out the
IP Address you can turn on the UPnP Support in Windows or use the “SearchNAS.exe”
Program on the CD to find out the IP Address.
Click on „Setup“
Click on “Exit
”
The actual IP Address of
the IB-NAS2000 is
displayed
IB-NAS2000 is found
To access the web management surface enter “http://<IP Address>” in the address line
of the Standard Web browser, where <IP Address> is the IP Address found by
SearchNAS.exe as described above. Continue with point “Using the management
interface” for setting up the IB-NAS2001 on Page 17.
13

Not configured Network / Direct Attachment
If the IB-NAS2001 is attached to a not configured network where no DHCP server
provides the IP configuration (or the IB-NAS2001 is directly attached to the computer)
and the computers are configured to use DHCP (which is default setting) the IB-NAS2001
will activate its own DHCP Server with the default IP Address 192.168.0.1 and will
provide IP Addresses in a range from 192.168.1.2 till 192.168.1.50 with a net mask4of
255.255.255.0, which is part of the subnet5192.168.1.1-192.168.1.254. In this case the
IB-NAS2001 can be reached by typing “http://192.168.1.1” in the address line of a
standard web browser.
Network configured on fix IP-Addresses
In a network where no DHCP Server is present and all IP-Addresses are configured
manually and fixed for example between 192.168.1.1 and 192.168.1.254 with
255.255.255.0 as net mask, 192.168.1.1 as default gateway6and 192.168.1.1 as
DNS server you have to define the IP Address of the IB-NAS2001 also manually.
To configure the IP Address of the IB-NAS2001 to for example 192.168.1.100 please
start the SearchNAS.exe on the CD and proceed as follows:
Attention: If you are unable to run SearchNAS.exe on your computer because you
are not using a Windows operating system please configure the IP-
Address of the IB-NAS2001 using the web configuration interface as
described in point “Network Setting” on page 46.
Click on „Setup“
14
4
The net mask defines which part of the IP Address is describing the subnet. Together with the IP Address it is the minimum
necessary part of the network configuration. So it always has to be set appropriate.
5
TCP/IP based networks, as the internet, are structured into different network parts called sub nets. A subnet is built by a set
of IP Adresses all having the same digital beginning. Remember: an IP Address is always interpreted as 32 bit binary number
containing 32 binary digits. IP Adresses of the same subnet all have the left part of these digits in common. How many of those
digits are used to define a subnet is described by the net mask. Computers in the same subnet are able to communicate
directly together. Computers in different subnets need a so called router which connects different subnets and forwards the net
traffic from one subnet into another.
6
In a TCP/IP based Network a computer can send directly data only to other computers in it’s own subnet. To be able to send
data to other computers, a rooter is necessary to link this subnet to the rest of the network and all computers in the subnet
need to know its IP Address because they will send all data for destinations out of their subnet to the rooter to be forwarded.
This IP Address of the router is defined by the default gateway setting.

A file system describes the way an operating systems stores data to a mass storage device. A file system may include
mechanisms for data organization, naming of files, access control, and system crash stability. Since mass storage management
is a very important task to an operating system a file system is deeply related to its abilities. Different operating systems are
orientated to different kinds of file systems and there philosophy.
