Networking Basics
All devices that connect to a network have an Internet Protocol (IP) address. This address is
used as a unique identifier on the network and allows communication between devices to
be routed correctl . IP is the standard used b all network devices.
A t pical home network will use a Modem/Router to connect to the Internet and will have a
number of devices connected directl to the Modem/Router. The Modem/Router acts as a
switch to allow intercommunication between the devices on the home network (LAN) and
allows each of the devices to access the Internet (WAN). The Modem/Router also offers
significant protection to the devices on the LAN side as the cannot be contacted directl b
a computer on the WAN side without the LAN side device initiating the communication. The
HDX should never e connected directly to the Internet without a Router in place.
It is usuall the Modem/Router that allocates IP addresses to the different devices on the
home network. The process of d namicall allocating addresses to devices is known as DHCP
and the part of the Modem/Router responsible for this is the DHCP Server. This s stem allows
devices to be connected and disconnected without the user having to make an
adjustments to the device configurations. Because this s stem is the most common and
convenient for home use the HDX ships with DHCP mode ena led. Below is a diagram of a
t pical home network setup:

HDX Network Settings
The HDX differs slightl from most other network devices as it has one network socket but two
IP addresses. Inside the HDX are two separate network devices. The Main Controller is
responsible for ripping CDs and audio pla back and has one IP address. The Front Displa
Controller runs the front panel user interface and has a different IP address. The Main
Controller and Front Displa Controller communicate with each other inside the HDX on a
small internal network, which is exposed on a single network socket. The diagram below
shows how the Main Controller and Front Displa Controller are connected inside the HDX:
The HDX is alwa s shipped from Naim Audio in DHCP mode, as this is the most common and
preferred addressing mode. It is possible to change from DHCP to Static mode using the Naim
Set IP Tool included on a CD ROM that ships with the HDX, although before doing so the
requirements of static IP addressing should be understood.
DHCP addressing mode
This is the preferred addressing mode and should alwa s be used unless it has been
determined that a static address is absolutel essential for a given installation.
In DHCP mode the HDX Main Controller and Front Panel Controller both acquire an IP address
automaticall when the HDX first starts.

Static addressing mode
Static addressing mode should onl be used in the following situations:
• The HDX is being used in a NaimNet or NetStreams setup.
• The HDX is being used with a ‘hardware VPN’ where the network administrator
allocates static IP addresses to each device.
• The HDX is being controlled via Ethernet b a Crestron or AMX control s stem.
• Port forwarding is used to control the HDX from outside the LAN.
• The HDX is to be controlled b a web browser and the network does not have a local
DNS server.
Some of the above scenarios are quite specialist. Unless it is has been determined that the
setup conforms to one of the above, DHCP addressing mode should alwa s be used.
To configure an HDX in static addressing mode the following settings must be known:
• Server IP address – This is the address of the server main controller. This address must
be unique and should not clash with the DHCP server’s address pool (if a DHCP server
is present). E.g. If the Netmask is 255.255.255.0 and the DHCP server allocates
addresses between 192.168.0.2 and 192.168.0.150 then the Server and Front Panel IP
addresses must be set between 192.168.0.151 and 192.168.0.254.
• Front Panel IP address – This is the IP address of the Front Displa Controller. Usual
practice is to allocate the front panel an adjacent address to the server IP address.
E.g. if the server IP address is 192.168.0.10 then the front panel IP address should be set
to 192.168.0.11.
Four ver important rules appl when choosing the addresses for the HDX:
o The Front panel IP address MUST e different from the server IP address
o Both Addresses must e unique (must not e the same as any other IP address
in the network)
o Both addresses must not overlap with the DHCP server address pool.
o Both addresses must e on the same range. i.e. if the server is on 192.168.0.10
and the Netmask is 255.255.255.0 the front panel must be on an address
between 192.168.0.1 and 192.168.0.254 (excluding the server’s own IP
address).
• Net Mask – This determines the range of IP addresses that can communicate with the
HDX. This should be compatible with the other devices on the network. For example
255.255.255.0 is a common Netmask.
• Gateway – This is the IP address that the HDX will use to access the Internet to perform
CD lookups.
• DNS – This is the Domain Naim S stem server that the HDX will use to resolve the IP
address of the Internet providers used for CD track information and album artwork.

Configuring the HDX networking settings
When the correct addressing mode and associated settings have been determined the HDX
can be configured. To do this the Naim Set IP Tool must first be installed on a PC running XP or
Vista. The HDX network settings are then reconfigured using this tool as described below.
After the HDX has been successfull configured it is advisable to make a note of the new
network settings in the back of the user manual for future reference.
Installing the Naim IP Tool Application
The HDX ships with a CD ROM that contains documentation, the Desktop Client application
and the Naim Set IP Tool. Note that the applications on the CD ROM require either Microsoft
Windows XP or Vista to run. The application will not nativel run on an Apple Mac computer
although there wa s of running Windows on a Mac, which are described in the
troubleshooting section. The following steps describe the installation process using Windows
Vista.
1) Insert the Naim CD ROM into the PC drive and locate the folder containing the Naim
Set IP application installer and double click the NaimIPTool.msi installer icon.

2) The Naim Set IP installer will open. Click Next > on the first screen. Then select the
Folder in which to install the application. The default location is shown below and will
be suitable for most t pical installations. Click Next > when read to continue.
3) Press Next > again to confirm then wait while the application installs.

4) When the installation is complete the following screen will be shown. Press Close to
complete the installation.

Changing the HDX IP address
1) Select the Naim Set IP Tool from the Start menu.
2) The Set IP Tool will launch and will start the server discover process. This process takes
30 seconds and scans the network for an Naim HDX hard disk pla ers or Naim
Servers.
3) When the discover process has finished the application will show the name and IP
address of an Naim servers found on the Network. In the example below an HDX
called NSHDXD22B has been discovered at IP address 199.199.0.46 and an NS02 at IP
address 199.199.0.253. Select the server that is to have its IP address changed and
click OK.

4) The application shows the current settings for the selected server. If the current
addressing mode is DHCP then Dynamic address (use DHCP) will be selected (see
step 5). If the current addressing mode is Static then Static address will be selected
and the address details will reflect the current network settings (see step 6).
5) To change the addressing mode to Dynamic select the DHCP option then click
Update. The application will now send the new configuration to the server and the
server will reboot (see step 6).

6) To change the addressing mode to Static, select the Static option and enter the
required networking settings. Follow the advice in the previous sections to determine what
these settings should be. Click Update when all the settings have been entered. The
application will now send the new configuration to the HDX and the HDX will reboot.

7) After the network settings have been changed and the Update button clicked (as
described in step 5 or 6) the following screen will be shown. The server will automaticall
shutdown then restart using the new network settings. Check that the message in the Update
Progress window confirms that both the server and front panel configurations were
downloaded successfull . The message displa ed should look like the message below. When
it has been confirmed that the configuration was sent successfull click OK to continue.
8) The following message will then be shown. Click Ok then close the Set IP Tool.
