Chapter 2. Installation and Set-up of
Network Disk Server
2.1 Installing the Hardware
The following steps will guide you through the Network Disk Server
hardware installation:
1. Connect the Network Disk Server™ to your Network.
Note: The system provides two to three network ports. To
configure Fail Over and Load Balance, at least two network ports
must be connected.
2. If you want to back up your files to the tape, please connect the
tape drive to the SCSI port on the back of your Network Disk
Server. Then turn on the tape drive. (This function is only
applicable for Network Disk Server models with SCSI port).
3. To use a UPS with your unit, please connect the UPS to the RS232 port on the back of your Network Disk Server via a serial
cable. And connect the power plug of the Network Disk Server to
the output power inlet of the UPS. (This function is only applicable
for Network Disk Server models with SCSI port).
4. Power on the Network Disk Server™.
Note: The power switch uses toggle switch design (after pushing
the button it will return to the original position). All you need to
do is to flip the switch one to turn-on or turn-off.
9
When all power cables have been properly connected, push the Power
Switch on the back of the Network Disk Server. The LCD Panel will
light up and the system is ready for set-up:
Server Name
NAS001122 05/22
192.168.0.1 02:48
IP Address
At this time the hardware installation of your Network Disk Server is
complete. Please proceed to “Set-up before First Operation”.
2.2 Set-up before First Operation
The factory default settings of your Network Disk Server will search
the network via DHCP (Dynamic Host Configuration Protocol) to
automatically detect IP address settings. If your network does not
support the DHCP protocol, the Network Disk Server will use the
default settings listed below:
IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
Once the Network Disk Server completes its boot-up process, the LCD
panel displays the current IP address settings.
If your network does not support the DHCP protocol, you must
configure your Network Disk Server to the proper LAN settings before
using it for the first time. (If you do not know your LAN settings,
please contact your network administrator).
1. Use the LCD panel to change the network settings. For more
information, see Appendix A.
2. Use the Quick Install Wizard on the CD-ROM to change the network
settings. For more information, see Appendix D.
Once you complete the Network Disk Server settings, you can use
your web browser to perform further administrative settings.

Chapter 3. Administration of Network
Disk Server
Once you have installed the Network Disk Server and other hardware and
connected it to the networks, you can use your browser (supports Microsoft
Internet Explorer 5.0 or later and Netscape Navigator 4.5 or later; Microsoft
Internet Explorer 5.5 is recommended) to complete administrative tasks for the
Network Disk Server.
3.1 Accessing the Administration Page
The following methods allow administrator to access the
Administration page:
1. Launch your web browser (Microsoft Internet Explorer version 5.5
is recommended). If you know the IP address of the Network Disk
Server, type the IP address in the address bar of the browser and
press “Enter”. The IP address can also be obtained on the LCD
display of the Network Disk Server (see Appendix A).
11
2. Use the Quick Installation Wizard (see Appendix D) and doubleclick on Network Disk Server in the list that appears. When the
browser displays the home page of your Network Disk Server, click
on the Administration link.

process step-by-step, as follows:
1. Enter the name, workgroup and description for this server.
2. Change the administrator password.
3. Enter the date, time and time zone for this server.
4. Select the language that this server will use for file names.
5. Enter the IP address, subnet mask and default gateway for this
server.
6. Select the network file services that you want to provide on this
server.
7. Configure disk volume on this server.
8. Configure the method of user authentication.
9. Manage users and user groups for this server.
10. Manage network shares on this server. It might take 3 to 10
minutes to complete the Quick Configuration depending on the
type of configurations.
3.4 System Settings
Basic system settings include the server name, date, time, and
language settings.
• Server Name
You must assign a unique name for your Network Disk Server for
ease of identification within the local network. The server name
can accommodate as much as 14 characters, which can be a
combination of letters (A-Z or a-z), numbers (0-9) and hyphens (-).
The server will not accept name containing blank spaces, period (.),
or names with only numbers. The LCD display will show the
current server name.
Next, you must configure your Network Disk Server to the
workgroup. The workgroup represents a basic computer group
within the Microsoft Network. Files are normally shared within the
group. Workgroups can accommodate as much as 15 characters
but must exclude the following characters:
The first character cannot be a period (.). For ease of management
and usage, please set your Network Disk Server and attached
computer(s) in the same workgroup.
Moreover, the Network Disk Server allows you to specify comments
(such as administrator name, department, or location) that
describe the Network Disk Server for ease of identification to an
on-line user.
; : " < > * + = \ | ? , [ ] /
14
• Date & Time
Set the date, time, and time zone according to your current
location. If the settings are incorrectly entered, the following
problems may occur:
1. When using a web browser to access or save a file, the time of
the file accessed or saved may be out of sync.
2. The system event log time will be incorrect compared to the
actual time an action occurred.
• Language Setting
The server is based on the language settings and uses it
accordingly while creating or displaying files and directories. Select
the correct language settings to avoid the following problems:
1. Inability to create files or directories with special wording.
2. Inability to display files or directories name with special wording.
View System Settings
You can view all the current system settings such as server name
and workgroup from this page.
3.5 Network Settings
The network settings include TCP/IP configuration and network service
settings.
• TCP/IP Configuration
According to your local network, you can choose the following two
methods to configure the TCP/IP settings:
i. Obtain IP address settings automatically via DHCP
If your network supports DHCP, the Network Disk Server will
automatically use the DHCP protocol to retrieve the IP (Internet
Protocol) address and related information.
ii. Use static IP address
Use the user defined IP address settings.
• Fixed IP Address
The IP address is a 32-bit digit code used to differentiate
each single entity on a network. The IP address is
separated into 4 groups of eight bits separated by dots:
192.168.0.1.
15
• Subnet Mask
The subnet mask is used to define computer within the
same local network. It is a 32-bits digit code:
255.xxx.xxx.xxx.
• Default Gateway
The gateway is generally referred as an interchange point
that connects two networks, such as LAN and WAN. If you
do not need to configure gateway address, set it as 0.0.0.0.
• Enable DHCP Server
Once the DHCP server’s dynamic address allocation function
is activated it will automatically assign dynamic addresses to
any computer in the network that is configured to
automatically obtain IP addresses.
Note: Only one DHCP server may be activated at any time
in a network to avoid causing conflicts in communication.
Configuration of Network Interfaces
The system supports multiple network interfaces that enable you to
perform Fail Over and Load Balancing functions. Fail over ensures
server availability to the network. If the primary port is
disconnected due to a hardware or cable problem, the secondary
port will replace its network identity. If the failed port resumes the
network connection, it will also resume the role as the primary
interface.
• Microsoft Networking
Users using the Network Disk Server on the Microsoft Windows
operating systems must start Microsoft Network Services.
If the local network has a WINS server installed, please specify the
IP address. The Network Disk Server will automatically register its
name and IP address with the WINS service. Or you can enable
your Network Disk Server as the WINS server for your network.
• Apple Networking
Users using the Network Disk Server on Apple’s Mac operating
systems must enable AppleTalk network support.
If your AppleTalk network uses extended networks, and is assigned
with multiple zones, please assign a zone name to the Network
Disk Server. If you do not want to assign a network zone, please
enter an asterisk (*). Asterisk (*) is the default setting.
16
• NFS Service
Users using Network Disk Server on Unix/Linux operating system
computer or server must start Unix/Linux NFS service. The
Network Disk Server supports NFS version 2.0/3.0. To correctly
use the NFS service, you must assign a User’s UID and IP address.
Please select User Management · Users · NFS Settings to start
the setup.
• NetWare Service
If you wish to use NetWare to access the Network Disk Server, you
must activate the NetWare service. The Network Disk Server will
then operate in a manner similar to a Novell NetWare 3.12 file
server.
• Web Service
Other than standard OS support, you have the choice to use a web
browser to access your files on the Network Disk Server. If your
Network Disk server is connected to the Internet and uses a valid
IP address, the Network Disk Server allows you to access your files
using a web browser from anywhere in the world.
• FTP Service
If you wish to download files from or upload files to your Network
Disk Server by using file transfer protocol (FTP), you must first
activate the FTP service.
• View Network Settings
You can view all the current system settings such as server name
and workgroup from this page.
3.6 Disk Configuration
Depending on the models, the Network Disk Server can accommodate
a maximum of eight disks. The Disk Volume can be configured
according to your needs.
• Single Disk
You can choose to use a stand-alone disk. However, if the disk is
damaged, all data will be lost.
• RAID 5 Disk Volume
Three or more hard disks can be teamed up to form a largecapacity RAID 5 disk group. This system will distribute and store
data among its various member disks as it is received. At the
same time it uses an amount of space roughly equivalent to a
whole disk to store reference numbers with the same elements.
Should one of the disks in the group suffer some kind of damage,
you can shut down the computer and install a new disk, and the
17
system will restore the data on the new disk using the reference
number. In addition, if you have a system with four disks but use
only three in your RAID 5 group, the fourth will serve as a backup
disk. If one of the three disks is damaged the system will
automatically start using the spare disk without powering down
and changing the affected disk. Generally speaking, the capacity
of a RAID 5 disk group is one disk’s worth of space less than the
total rated capacity of the group.
Note: RAID 5 may be used only with equipment that has three or
more disks.
• RAID 1 Mirroring Disk Volume
Mirroring Disk protects your data by automatically backing up the
contents of one disk onto the second disk of a mirrored pair. This
protects your data if one of the disks fails. Unfortunately, the
storing capacity is equal to a single disk, as the second drive is
used to automatically back up the first. Mirroring Disk is suitable
for personal or corporate use to store important data.
• RAID 0 Striping Disk Volume
Striping disk combines two or more disks into one larger disk. It
offers the fastest disk access but it does not have any protection
of your data if the striped array fails. The disk capacity equals
the number of disks in the array times the size of the smallest
disk. Striping disk is usually used to maximize your disk capacity
or for fast disk access but not for storing important data.
• Linear Disk Volume
You can combine two or more disks into one larger disk. During
file saving, the files are saved on physical disks sequentially but
do not have a disk failure file protection function. The overall
capacity of linear disks is the sum of all disks. Linear disks are
generally used for storing large data and are not appropriate to
use for file protection of important data.
By factory default, the Network Disk Server has been pre-set into one
large disk. If you wish to use other disk configurations, the settings
can be changed during the first Quick Configuration access.
Furthermore, to increase the hard disk life, the hard disk will go to
standby mode if there is no access within 30 minutes. If any data
access happens while the hard disk is in stand-by mode, it will take 3
or 5 seconds for the hard disk to return to normal mode. You can
select System Tools · Hardware Settings to change the setting.
You can also perform the following disk administration:
• Create Disk Volume
• Delete Disk Volume
• Examine Disk Volume
• Format Disk Volume
• View Disk & Volume Status
18
In addition to the above functions, users can also perform snapshot
taking in Snapshot Settings of System Tools. This function enables
users to take a real-time and dynamic replication of the snapshot
according to the disk volume at a certain point of time. The data
contained in the snapshot is the same as the previously copied network
hard disk drives. The content in the snapshot will not be affected even
when changing the content of the disk volume. If an original data is
damaged, it can be restored from the snapshot image.
3.7 User Management
The Network Disk Server can share its files with multiple users. It is
important to plan and organize users and user groups’ accessibility to
ease the administration work.
• Users
The factory default settings include the following users:
Administrator
By default, the administrator is a member of the administrators
group and has access to the system administration. You cannot
delete the user Administrator.
Guest
When you use a non-registered user name to login, the server
recognizes it as a Guest and will allow limited access. A guest does
not belong to any user group. You cannot delete the user Guest or
create a password.
Anonymous
When you connect to the server by FTP service, you can use the
name to login as a guest. You cannot delete this user or change its
password.
You can create a new user according to your needs. The following
information is required to create a new user:
• User Name
The user name must not exceed 32 characters. It is case
insensitive and it can contain double-byte characters. (Such as
Chinese, Japanese, and Korean) But it cannot contain any of
the characters below:
" / \ [ ] : ; | = , + * ? < > ` '
• Password
The password must not exceed 16 characters. Due to security
concerns, the password must be at least 6 characters. Try to
avoid using codes that are easily decipherable.
19
You can perform the following settings for users:
• Create User
• Create Multiple Users
• Create Private Network Share
• Assign User Groups
• NFS Settings
• Quota Settings
• Delete User
• User Groups
To administer access rights, you can create user groups. User
groups are a collection of users with the same access rights to files
or folders. By factory default, the server contains the following
pre-defined user groups:
Administrators
All members of the administrator group have the rights to perform
system management. You cannot delete the administrator group.
Everyone
All registered users belongs to everyone group. You cannot delete
the user groups, “Everyone” or delete any of its users.
You can manage user groups with the following options:
• Create User Groups
• Create Private Network Share
• Assign Users
• Delete User Groups
User groups name must not exceed 256 characters. It is case
insensitive and it can contain double-byte characters such as
Chinese, Japanese, and Korean. But it cannot contain any of the
characters below:
" / \ [ ] : ; | = , + * ? < > ` '
To properly manage security, it is very important to manage users
and user groups. You may set the share access parameters of each
user or user group accordingly.
• PDC Authentication Settings
If you have a Windows PDC (Primary Domain Controller) server to
handle the domain security in your network, you don’t need to reenter all the users and groups with the Network Disk Server. You
can simply enable the PDC authentication feature; the Network
Disk Server will connect with the NT domain and get all the
information of the domain users and groups automatically.
To enable PDC authentication, you must enter the domain name as
well as the user name and password already established in this
domain. The Network Disk Server will use the user name and
password to log in to the NT domain and retrieve user and group
information. Once you have configured the Network Disk Server to
20
use PDC authentication, all NT domain users and groups will appear
in lists of users and groups for which you can define access rights.
Note: NetWare users cannot be authenticated via the PDC server.
To properly authenticate NetWare users, please go to User
Management · Users · Change Password page and type the
password for that user manually.
• Quota
The amount of space given out to all users in the system can be
limited in order to manage and allocate it efficiently. Once these
restrictions are in place, users will be prevented from obtaining
more space once they have reached their limit. This prevents
monopolizing of a large amount of disk space by a small group of
users. No limitations are set on the system when it leaves the
factory.
3.8 Network Share Management
The primary purpose of network storage is file sharing. In a standard
operation environment, you can create different network share folders
for various types of files, or provide different file access rights to
users or user groups. By factory default, a “public” share folder is
created. The share folder gives full access to all users or guests.
Administer network shares with the following:
• Create a Network Share
• Change the name, path and comment of a network share
• Set access right for a network share
• Remove a network share
You can create new network shares according to your needs. While
creating a network share the following parameters must be set:
• Network Share Name
The network share name must not exceed 32 characters. It cannot
contain double-byte characters (such as Chinese, Japanese, and
Korean) as well as the characters listed below:
" . + = / \ : | * ? < > ; [ ] %
• Disk Volume
The network share will be created under the specified disk volume.
• Path
All data are stored under the assigned path onto the disk volume.
You can select Specify Path Automatically to allow the server to
automatically create a new path on the disk volume to store the
network share files. Or you can assign a specific path for the share
folder. The manually assigned path cannot exceed 256 characters
and cannot contain the characters listed below:
21
" \ : | * ? < > ; ` '
• Comment
The Comment field allows a brief description of the share folder to
help users identify its purpose in a network neighborhood window.
The comment cannot exceed 128 characters.
Once the network share is created, you can start assigning access
rights to users or user groups:
• Full Access
Full access allows the user or user group to read, write, create, or
remove all files and directories in the network share.
• Read Only
Reads files only in the network share but denies functions to write,
create or delete files or directories.
• Deny Access
Denies all files access on the network share.
3.9 System Tools
The following system tools allow optimized maintenance or
management of your Network Disk Server:
• SNMP Settings
In order to use Simple Network Management Protocol (SNMP) to
manage the Network Disk Server's network components, the SNMP
service must be started.
• Alert Notification
Configures administrator’s e-mail address and SMTP server IP
address. In case of warning or malfunction, an email is
automatically sent to the administrator.
• Restart / Shutdown
Powers off or restarts the Network Disk Server.
• Hardware Settings
You can enable or disable the following hardware functions of your
Network Disk Server:
i. Enable LCD panel setting function
Allow you to change the TCP/IP configuration using the LCD
panel buttons.
22
ii. Enable configuration reset switch
Depress and hold on the configuration reset switch for 5
seconds to reset the administrator password and network
settings to the factory default.
iii. Enable hard disk standby mode
Hard disk will go to standby mode if there is no access within
the period you specify.
iv. Enable buzzer
If the buzzer is disabled, it will not sound when a system error
occurs, but the warning light will still shine.
• UPS
By enabling the UPS support, you can protect the system from
abnormal shutdown caused by power outage. In the event of utility
power failure, the system will shut down automatically by probing
the power status of the connected UPS unit. You can also set a
shutdown timer to turn off the system automatically after it detects
the AC power failure. In general, the UPS can keep supplying the
power for the system for about 5 to 10 minutes. But this depends
on the maximum load of the UPS and the number of the loads
connected to it.
The UPS is supported by the following two ways:
i. via a serial port interface (only for models with serial port)
ii. via SNMP network management protocol
If the UPS you used is not supported, please contact technical
support or visit our web site for updated news.
• System Update
Performs system software updates. Make sure that the image file
that you are about to update is the correct version and read
through the instructions carefully. It is wise to back up all existing
data on the Network Disk Server prior to performing system
software update. The current settings will remain unchanged after
the system is upgraded.
• Change Logo
You can place a picture that you desire on the upper right corner of
the home page. The size of the picture cannot exceed 20K bytes.
• Tape Backup (Applicable for models with SCSI port only)
The tape backup tools allow you to perform the backup or restore
jobs using a tape drive with ease. In principal, there are two
different types of backups: Full Backup or Incremental Backup. Full
backup will back up all the files in the backup source. However, the
incremental backup will only back up any modified or new files after
last backup.
23
Backup Now
To back up the files to the tape right away, you can run an
immediate backup job.
Restore
To restore from the previously backup tape, you can perform the
restore operation.
Scheduled Jobs
You can schedule a backup job to be executed automatically at any
later time periodically.
Tools
There are several useful tape functions to operate on the tape
drive. For example, you can rewind, eject or erase the tape here.
Job Status
You can review or monitor the status of the backup or restore job.
Note:
1. The SCSI tape drive has to be properly connected and turned
on before starting the system, or it will not be detected.
2. The HVD (High Voltage Differential) SCSI tape drive is not
supported by this system.
• Remote Replication
When you want to replicate the local files to the remote folder on
another Network Disk Server, the remote replication function allows
you to perform this job with ease. You can perform immediate
replication job or schedule a replication job to be executed at the
specified time periodically. In order to reduce the network
bandwidth usage as well as the time consumed, you can select to
compress the files before transferring them over the network.
• Virus Scan
Virus scanning agent helps you protect your system from being
infected by viruses. You need to operate Windows NT or Windows
2000 server with virus-scanning software installed to perform realtime virus scanning. To enable virus scan support, specify the IP
address of network share, the administrator IR and password.
Infected files are automatically deleted or quarantined by the NT
virus-scanning software as setup by the NT administrator.
