Introduction
The NAS Server
Congratulations on the purchase of GNS-2000. The NAS inserts Gigabytes of storage
space into your network without the cost, space, and maintenance hassles of a full-fl
edged file server. The NAS provides solid data transfer performance for multiple client
connections. And you can add as many NAS Servers to your network as you like. Com-
pared to using a standard PC as a File Server, GNS-2000 offers lower cost, easier
management, and increased reliability.
Windows utility software is provided for the NAS Administrator. Also, the Web-based Ad-
ministration interface offers a wide array of management options.
Web-based file system

Configuring Your GNS-2000
Now that everything is connected and powered on, you are ready to configure your GNS-
2000 so that it is accessible to the users on your network.
This procedure only needs to be done ONCE, by the NAS Server's Administrator.
Other LAN users should follow the Client PC Setup procedure described in the follow-
ing chapter.
Quick Setup with the GNS-2000 Wizard
1. Insert the NAS CD into your CD-ROM drive of your computer.
If the installation program does not start automatically, run the program
NAS_Setup.exe in the root (top) folder of your CD-ROM.
2. Click "Setup" to start the Setup Utility. The Utility will begin scanning your network for
installed GNS-2000 Servers, and a screen like the following will be displayed.
A list of all GNS-2000 Servers on your network will show on the left side. The right side
displays details of the currently selected NAS.
If the desired GNS-2000 is not listed, check the following:
GNS-2000 has finished the start up and boot process.
Your PC and GNS-2000 are on the same LAN segment (there is no Router be-
tween your PC and GNS-2000).
Otherwise, select the desired GNS-2000, and click the "Next" button.

Obtain an IP address
automatically
(DHCP Client)
Select this only if your LAN has a DHCP Server. Normally,
it is better for servers to use a Fixed IP address (see below)
Fixed IP Address
This option is recommended. If this option is used, the IP
address or GNS-2000 will never change. You need to
enter the following data.
IP address - The utility will suggest an unused IP
address within the address range used on your LAN. If
you wish, you can change this, but you must ensure the
address is unused.
Network Mask - This must match the value used by
PCs on your LAN.
Gateway - This must match the value used by PCs on
your LAN.
4. Click "Next" to continue. The following screen will then be displayed:
The following data is required.
Server Name:
The Default Name is shown. Change this if you wish.
Workgroup
Name:
Normally, this name should match the Workgroup name used by
PCs on your LAN.
Select this if your LAN has a DHCP
server, otherwise select “Fixed IP
Address”.
Suggested values are compatible
with your LAN. Suggested IP ad-
dress is currently unused.
Each interNAS/USB comes with an
unique server name. You may
change it if you wish.
All workgroups on the network are
listed. You may select one from the
pull-down menu, or create a new
one.
Set the proper Time-Zone, Date and
Time here.

Date/Time
Enter the local date (mm/dd/yyyy format) and time.
5. Click "Next" to continue. The following screen is displayed.
6. Click "Save" to save your data to GNS-2000.
On the resulting screen, click "Exit" to close the Setup Utility. GNS-2000 is now opera-
tional.
Other Configuration
After the configuration above, all Windows users can access the NAS with "guest" access
rights. This allows access to the public shares (by default, DISK and FLASH or USB HDD).
However, we recommend creating a GNS-2000 "User" for each person on your LAN. This
will provide each person on your LAN with their own login (name and password) as well as
their own personal folder on GNS-2000.
See the Administration chapter for details on creating users via the Web-based interface.
All settings are displayed.
Please confirm they are corrected,
then click “Save”.
After saving, a final screen will be
displayed.
