FCC Compliance

This equipment has been tested and complies with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. If not installed and used in accordance with proper instructions, this equipment might generate or radiate radio frequency energy and cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measurers:

Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is

connected. Consult the dealer or an experienced radio/TV technician for help.

Shielded interface cables must be used in order to comply with emission limits.

Safety Precautions

Before getting started, read the following important cautions.

1. Be sure to ground yourself to prevent static charge when installing the internal components.

Use a grounding wrist strap and place all electronic components in any static-shielded devices. Most electronic components are sensitive to static electrical charge.

Disconnect the power cords from the NAS server before making any installation. Be sure both the system and the external devices are turned OFF. Sudden surge of power could ruin sensitive components. Make sure the NAS server is properly grounded.

3. Do not open the system’s top cover. If opening the cover for maintenance is a must, only a

trained technician is allowed to do so. Integrated circuits on computer boards are sensitive to static electricity. To avoid damaging chips from electrostatic discharge, observe the following precautions:

ü Before handling a board or integrated circuit, touch an unpainted portion of the system unit chassis for a few

seconds. This will help to discharge any static electricity on your body.

ü When handling boards and components, wear a wrist-grounding strap, available from most electronic

component stores.

switch of the power supply to ON position.

Step 4: The red system LED is continuously on for 2 seconds, then the green system LED flash

rapidly (one flash per 0.5 second) indicating the NAS-5400 is booting.

Step 5: The continuous green LED indicates the NAS-5400 is ready to use. Note: NAS-5400 has two power supplies by default. If you only deploy electricity to one power

supply, the Power Fail Buzzer would keep beeping for warning. You can turn it off by pressing the red button (Power Fail Buzzer Reset Button), which locates at the right side of the rear panel.

2.2 Installing Hard Drives to HDD Trays

The NAS-5400 has four hot-swappable HDD trays, which can be used to install 3.5” IDE hard drive each. You don’t’ need to turn off the server when replacing a failed hard drive. The hard drive must be 3.5” ATA66/100/133 IDE compliance. The hot-swappable drive tray connects to the backplane. The backplane is the printed circuit board behind the bay.

Note:

1. Do not use any other drive tray which is not designed for NAS-5400, or a serious damage

might be caused.

2. For best flexibility, the NAS-5400 is designed to fit most types of hard drive form various

hard disk drive vendors. But each of them might have slightly different mechanical dimension. We strongly recommend applying hard drives with the same type or with the same dimension to NAS-5400.

2.3 Setting Up the NAS-5400

After connecting the NAS-5400 to a power cord and the LAN, power it up and follow the procedures below to set up the server.

1. Choose a computer in the same network as NAS-5400 running Microsoft Windows 98/ME/NT/2000/XP and an IE5.0 (or above) web browser installed.

2. Insert the bundled CD in the CD-ROM drive to initiate the autorun program. Once completed a menu screen will appear as follows:

3. Click on the "NAS-5000 series Assistant" hyperlink to activate the program.

If the above screen is not shown, you can start the installation as follows.

A. Click on Start Menu/ Run. B. Enter “E:\UTILITY\Assistant\Windows\ NAS5000SeriesAssistant.exe” in the appeared

box, where “E” is the letter of your CD-ROM drive.

C. Click on “OK” button.

4. NAS-5000 series Assistant will automatically search and list all available NAS servers on the LAN. The Server Status column will show current status of the server.

Suppose you want to set up a server called NAS-5400 for the first time. By default the system obtains the network configuration information through the DHCP server. If a DHCP server does exist on the LAN, its IP Status will show DHCP, referring that the NAS-5400 has correctly received IP from DHCP server. Please double click the server name or click the Manage button, and NAS-5000 series Assistant will automatically activate the browser, connect to the server’s IP address, and then start the Quick Configuration. Please refer to user’s manual for more details.

5. If there is no DHCP server on the LAN, or the client that runs NAS-5000 series Assistant does not belong to the same network as NAS-5400, the IP Status column will show Unknown instead.

Note: If the NAS-5400 supports more than 1 network interface, the NAS-5000 series Assistant will show only one of them for system administrator to configure. To configure the other network interfaces, you must access the Server Configuration page of NAS-5400 to setup.

Double-click on the server name NAS-5400 to open the network configuration screen. Input password into System administrator password field; the default value is blank. You can either select Get Network Configuration through DHCP to automatically configure the network through the DHCP server, or choose Use Manual Configuration and enter the IP address,

domain name, subnet mask, gateway, and DNS server. The setup program will get the network configuration for your reference. If the information is not enough, click on Suggestion; the setup program will check available IPs on the LAN and provide a suggested IP address.

6. Click Apply to confirm the network settings. The program will automatically activate the browser and connect to the server’s IP address, then start the Quick Configuration.

If the NAS-5000 series Assistant cannot locate your NAS-5400 or fails to setup, please verify followings before trying again.

1. Make sure the power cord is attached and the server is start up successfully.

2. Make sure the server has an active LAN connection. You can verify it by checking the LAN LED status on the panel of NAS-5400.

3. Make sure the managed computer (which is running NAS-5000 series Assistant) and the NAS-5400 are physically in the same LAN.

4. Make sure the managed computer has installed and set the TCP/IP protocol, and is running Microsoft Internet Explorer 5.0 or above.

5. Make sure the selected server name is correct.

6. Make sure the LAN still has valid IP addresses.

7. Make sure the manually configured network settings are correct.

2.4 Replace the hot-swap redundant power supply

The NAS-5400 comes with two power supplies; each has a LED indicator. If the power cord is connected and the A/C switch is at ON position, but the LED is still off, the power supply is failed. Please follow the procedures below to replace it.

1. Switch-off the AC switch of the failed power supply. Disconnect its power cord.

2. Unlock the thumbscrew of the failed power supply.

3. Pull out the failed power supply by the handle. Replace a new one and lock the thumbscrew.

4. Connect the AC power cord and switch on the power.

2.5 Turn off the NAS Server

There are two ways to turn off the NAS-5400.

1. When the NAS-5400 is running, you can turn it off by pressing the power control button once. The NAS-5400 will shutdown automatically after around 20 seconds. Do not press the power button continuously for over 4 seconds, for this action will turn off the power immediately and may cause the server non-operational or corrupt the drives.

2. You can turn off (shutdown) the NAS-5400 via Toolkits option of its web management interface.

Chapter 3

Quick Configuration

The NAS server offers a simple and easy-to-use approach, which called NAS-5000 Series Manager, for administration. Use this manager to configure the server, system and network parameters, including Windows, UNIX, and Apple Macintosh network settings, as well as the hard disk configuration.

When you install the NAS server for the first time, PLANET NAS-5000 series Assistant will complete the IP configuration of the server, then automatically activate the web browser to connect to the server. The Quick Configuration page with basic configuration options will appear. Please follow the instructions to complete all steps.

Note:

1. There are always hints on the right side of the screen during setup procedures. You can

obtain some useful information of every screen there.

2. This system only supports Microsoft IE 5.0 browsers or above. Netscape or other browsers are not supported.

Step 1: Enter the root password

Since this is the first time using this system, the system will prompt for changing the default root (system administrator) password. Make a note of this password for future access to the NAS server.

The password is case sensitive, and up to 12 displayable characters can be entered, including letters, numbers, signs, and space, etc. However, the password of root cannot be empty. After entering the password, please confirm your choice by re-entering it in the Confirm password field.

Step 2: Basic server configuration

System administrator can change the default server name here and further configure the network settings. Please note that the server name must be unique, meaning that no other server in the network should have the same name. The name is not case-sensitive and cannot exceed 15 characters. The first character must be a letter; the other characters can be letters, numbers, the underscore or minus sign.

This system supports up to four domain names and three DNS servers. The length of the domain name cannot exceed 64 characters. If the existing DHCP server has already created multiple domain names and DNS server setup while NAS server obtains its network settings from DHCP server, this page will capture the first item from the DHCP server. The system administrator must specify other items manually.

Step 3: LAN port 1

Next, please setup the IP address of the first network card. This page will show the setup information previously defined in PLANET NAS-5000 series Assistant, and system administrator can make additional change here.

If the LAN includes a DHCP server, click “Get network configuration through DHCP”. Otherwise, choose “Use manual configuration”, and fill out the related settings. Filling out the column with a red star sign on the right is mandatory, while filling out the column with the orange star is recommend by the system.

Step 4: Enter the system date and time

Use a 24-hour format to enter the system date and time, as well as the correct time zone. The NAS server will automatically adjust itself if daytime saving time (DST) is applicable to the selected time zone. There is no need for extra setup.

To activate network time synchronization, please choose “Enable network time synchronization”, in the “Period” pull down menu, choose the appropriate period, and then fill out the hostname or IP in the Primary time server field. If a spare time server is available, fill out its hostname or IP in the Secondary time server field. When the primary time server is failed, the NAS server will try to synchronize the time with the secondary time server.

Note: Please find below NTP server web address for your reference to set the time server. http://www.eecis.udel.edu/~mills/ntp/clock1a.html http://www.eecis.udel.edu/~mills/ntp/clock2a.html

Step 5: Select a language

You can perform all the language settings on this page. Please choose a display language for NAS-5000 Series Manager, event notification emails, and the code page for different kinds of client.

In Display Language column, when selecting Browser Default Language, NAS-5000 Series Manager will automatically display the same language as the browser of the client when system administrator or general user is connected to NAS-5000 Series Manager.

For some languages at least 2 sorting methods are available for the administrator to choose. The sorting method is used to sort information on NAS-5000 Series Manager, such as shared folders and user accounts. The sorting method can be chosen from the “Sort by:” pull-down menu.

Encoding for Windows/ Apple will be applied for the three clients, and allow them to access the server correctly with the defined encoding when Unicode is not available. After selecting the encoding for Windows/ Apple, please select the appropriate encoding for NFS clients under the same locale language.

Once Quick Configuration is complete, NAS-5000 Series Manager will use that language. If you do not know the correct code page of your Windows client, enter the command “chcp” in the

command prompt and press Enter to retrieve the correct code page information.

Note:

1. Inconsistent codepage settings between the system and the clients will result in incorrect

display on accessing the data. The system codepage must be the same with that of the clients.

2. If the administrator set a single-byte language (code page), such as English, for Windows

clients, an error will occur when the client attempts to save double-byte files or folder names (e.g. Traditional Chinese) on the NAS server, and some files cannot be deleted once saved. In this case, the system administrator must use the Server ConfigurationàLanguage Setup to change the code page to double-byte encoding; only then can the file be properly accessed and deleted.

Step 6: Enter a recipient for notification

NAS server can notify the system administrator of important events via e-mail. Enter a SMTP server and the primary e-mail address 1. When an important event occurs, the system

administrators will be informed via e-mail and can respond immediately, thus ensuring system safety. You have the option to send a test message after setup to make sure you have entered a valid configuration.

Due to the excessive amount of junk mail pervading the Internet, many providers do not allow their SMTP servers to be used by outside users. We therefore strongly recommend using the SMTP server of your e-mail domain (the address 1, address 2). E.g., if you use root@abc.com, select the SMTP server belonging to this provider, for example mail.abc.com.

Note: if you enter the host name (e.g. mail.abc.com) of the SMTP server, instead of the IP address (e.g. 192.168.1.1), please also enter the DNS address to ensure the notification emails can be sent to administrators.

Step 7: Cache setup

In order to improve data access performance, you can select to turn on "Disk write cache" support on this page. It is suggested that an UPS is accompanied with the server if this option is turned on to prevent from data loss when abnormal power failure occurs.

Step 8: Completing Quick Configuration

Once you have completed the Quick Configuration, the NAS server should operate properly on the LAN. Click “Finish” to apply all settings and activate NAS-5000 Series Manager.

Chapter 4

Using NAS-5000 Series Manager

After the Quick Configuration is complete, the NAS server will open the web-based NAS-5000 Series Manager program, where the system administrator can further edit the settings of the server.

Note:

1. NAS-5000 Series Manager does not include a Back option, but lists all of the configurable items on the left-hand side of the browser window. When you are done with one screen, simply select the next item you wish to configure from the list on the left.

2. If no entry modification in NAS-5000 Series Manager for 15 minutes, you will automatically be logged out, and will have to log in again to continue.

4.1 Server Information

You can obtain information about your NAS server here.

General tab

Shows system version and manufacturer information.

Configuration tab

Shows the current configurations of the server. You can change these settings under Server Configuration.

Status tab

Shows the current operation status of the server, including network port (s) and hard disk usage. If an error occurs on the server, such as network card malfunction or hard disk failure, the information on this page will be immediately updated, and a notification message will be sent via e-mail to the system administrator.

Moreover, when the hard disk is at “Damages in system area” or “With bad sectors” status, you can check the bad sector details of the hard disk by moving the mouse over the hard disk graphics on this page. When bad sectors occur on the hard disk, the NAS server provides a Dynamic Bad Sector Recovery (DBSR) mechanism by reserving a space on each partition of the hard disk for mapping bad sectors when bad sectors are used and recovering data in the future, so the file can be protected against access failure.

i. Bad sector mapping: If a HDD bad sector is used when writing data to an existing volume,

the bad sector will be automatically mapped to the reserved space. Any request for the data in the future will be redirected to the mapped space.

ii. Bad sector recovery: On a RAID1 volume, if a HDD bad sector occurs on an existing data

entry, when reading the data, the system will still generate the correct data by calculating the RAID1 consistency and map the data to a reserved space. Any request for the data in the future will be redirected to the mapped space.

There are three available LAN interfaces in NAS-5400. Thus you can team these ports in Trunking mode or Fail-over mode.

“Trunking” is also known as "Link Aggregation"; it simulates two LAN ports belonging to the same team into one large-scale LAN port thus multiplying the overall network bandwidth. These LAN ports share the same IP. Should any LAN port fail, the other LAN port could still provide services. Trunking mode can only applied to two ports with the same bandwidth. So you can only trunk LAN port 1 and LAN port 2 together. For example, if a NAS server trunks two 100 Mbps LAN ports, the bandwidth will expand to 200 Mbps. Should any of the LAN port fail, the other one in the same team will continue to serve.

Note: “Trunking” is only available when coupled with a switch supporting CISCO Fast EtherChannel (FEC), and is only allowed on LAN ports with the same bandwidth.

The “Fail-over” mode provides a redundancy solution. Should any LAN port fail, the other port in the same team would take over its job and continue to provide services. Multiple network adapters with different bandwidths can be teamed as “Fail-over”. In this case the network adapter with larger bandwidth will be used as the master network adapter. When the master network adapter fails, the other network adapter will take over the service.

Moreover, all LAN ports teamed together must be set in the same mode. For example, suppose the LAN port 1 and LAN port 2 is in Trunking mode already, and you configure the LAN port 3 in “Fail-over” mode, then all LAN ports will be switched to “Fail-over” mode.

Or, if a network has more than two subnets, system administrator can setup each network card separately into different subnet IP address to achieve the "Load Balancing" effect.

Note: If these LAN ports are not configured in “Fail-over” mode, you must assign three IP addresses in different subnet to the cards respectively, thus when choosing network type through DHCP, please make sure if the subnet has any DHCP server available for use.

Routing table tab

Use this page to configure the routing table. To add a new route, please enter the gateway in the

“Gateway” field. You can select “Default gateway” or enter appropriate data in the “IP address” or “Subnet/Mask” fields, then click “Create” button. After finish adding all route records, click “Apply”

button to save the configuration.

4.2.2 Date Setup

4.2.3 Language Setup

You can perform all the language settings on this page. Please choose a display language for NAS-5000 Series Manager, event notification emails, and the code page for different kinds of client.

Once Quick Configuration is complete, NAS-5000 Series Manager will use that language. If you do not know the correct code page of your Windows client, enter the command “chcp” in the

command prompt and press Enter to retrieve the correct code page information. Note:

1. Inconsistent codepage settings between the system and the clients will result in incorrect display on accessing the data. The system codepage must be the same with that of the clients.

2. If the administrator set a single-byte language (code page), such as English, for Windows clients, an error will occur when the client attempts to save double-byte files or folder names (e.g. Traditional Chinese) on the NAS server, and some files cannot be deleted once saved. In this case, the system administrator must use the Server ConfigurationàLanguage Setup to change the code page to double-byte encoding; only then can the file be properly accessed and deleted.

4.2.4 Notification Setup

NAS server can notify the system administrator of important events via e-mail. Enter a SMTP server and the primary e-mail address 1. When an important event occurs, the system administrators will be informed via e-mail and can respond immediately, thus ensuring system

safety. You have the option to send a test message after setup to make sure you have entered a valid configuration.

4.3 Security Setup

In this section, the administrator can define users and user groups to access certain files and folders on the NAS server.

4.3.1 Shared Folder Setup

Shared Folder tab

The administrator can use this option to add, modify or delete shared folders and select whether folders can be exported via NFS to allow UNIX access only.

Shared folder name is not case sensitive. It can be up to 15 characters except for the following characters:

! " # $ % ' ( ) * + , / : ; < = > ? @ [ ] \ ^ ` { } | ~! Besides, the first character cannot be minus sign, and space; the last character cannot be space. Note: NAS-5400 allows up to 64 shared folders, not including the home folders of “users” group

accounts. The option “Path” is only available for NFS and cannot be edited manually. The system will

automatically enter the path “/volumen/Shared_Folder_Name” for each shared folder on the NAS server. For example, if you create a shared folder called “test” on a volume on the NAS server, the system will automatically assign the path “/volume1/test”. The administrator cannot change this default value.

Once the shared folder is created, the system administrator must use the “Windows/Apple

Privileges” or “NFS Privileges” tabs to choose users and their access privileges. All files stored in the shared folder will have the same privileges.

Default shared folders

By default, NAS-5000 Series Manager will create a shared folder named “publicn” on each individual volume, whereas n represents the disk volume. For example, if there are 2 volumes on a NAS server, the folders will be named “public1”, and “public2” respectively. However, if system administrator segments the storage space into multiple volumes, then the system will automatically create a “publicn” shared folder for each volume.

The name, description, and path of this folder (/volumen/publicn) cannot be changed by the administrator. By default, any user logged into the NAS server has full read/write access privileges to this public folder. System administrator can change the user access rights of this shared folder through “Windows/Apple privileges” or “NFS privileges” tabs.

Adding a shared folder

To add a folder, please follow the steps:

1. Click on “Create”. The “New Shared Folder Setup” page will appear.

2. Enter “Folder name” and “Comments” fields for the folder.

3. Select a proper location from “Location” drop down menu to place this folder.

4. Choose a permission style for this new shared folder in “Security” field.

5. Click on “OK” to complete the configuration, or click on “Next” to add another new shared

folder. After the shared folder is setup, it does not matter if the shared folder is Window compatible or

UNIX compatible. All the users with proper privileges can press the right button on the shared folder under Windows’ network neighborhood to reset the privileges.

Note: When Windows 98 clients connect to the NAS server through Windows “My Network Places” or the Mac OS X clients through “Samba”, they can only access shared folders with folder name as many as 12 characters. Thus when sharing with these clients, the length of the shared folders’ name should not exceed 12 characters.

Modifying a shared folder

Click on an existing folder name to display the information pertaining to this folder in the right windowpane. To rename the folder or modify its description, make the necessary changes on the right and then click “Apply”.

Deleting a shared folder

To delete a shared folder, select the desired folder (use Ctrl for multiple and Shift for continuous selection) in the list on the left pane, then click “Remove”. The default shared folders “publicn” cannot be deleted.

Windows/ Apple User Privileges tab

The system administrator can use this page to assign access privileges for local users/groups (i.e. Windows/Apple clients with accounts on the NAS server) and Windows domain users/groups. Use the drop down menu to choose a folder in the “Folder name” list, the “User privileges” column will show all the users or groups entitled to access the selected folder.

Note: Mac and Windows clients can share the same folder. However, since Mac and Windows systems handle file associates in different ways, the access to the files supported by both Mac and Windows systems such as “pdf” and “html” may be restricted.

For example, when a Windows client saves an html file to the NAS server, a Mac client cannot double-click this file on the server to open the file by automatically launching the web browser. Because the way Windows system saves “Associated file type” differs from that of Mac, Mac system does not know with what program it can open the html file created in Windows.

There are two solutions for it:

1. Re-establish the associate of this file on the Mac client.

2. Launch the program used for executing the file on the Mac client first. In this case launch IE or Netscape and then open the file with the browser. Alternatively, use “save as” to save the file on the Mac client so that the new file will be saved in the Mac format. To open the file, simply double-click it.

When the Windows client cannot directly execute files saved by the Mac client, the same solution can also be applied.

Modifying User Privileges

To change existing user privileges, e.g. from “Writeable” to “Read only”, select the user whose privileges you wish to change in the “User privileges” column, then select “Read only” in the center column, and click “Apply” to confirm your selection.

Adding user privileges

To add user or group privileges under a particular folder, please follow the steps:

1. Select a user or user group in the “User account:” column (use Ctrl for multiple and Shift for

continuous selection).

2. Click on “No access”, “Read Only” or “Writeable”. Press “Apply” to complete.

Note: if this NAS server is added to the Windows domain, and (1) system administrator has previously added certain Windows domain user account to Local account or (2) there is an account in both NAS server and Windows domain with the same name, then the users account list on the left will not show the account number in NT Domain Users but only in Local Users to prevent system administrator from confusion caused repeated setup of access rights for the same user.

Deleting User Privileges

To delete user or group privileges, please follow the steps:

1. Use the mouse to select a user or user group in the “User privileges” column (use Ctrl for

multiple and Shift for continuous selection).

2. Then click “Remove”.

3. Press “Apply” to complete.

Note:

1. When setting Windows/Apple user privileges for the shared folders, make sure to avoid

possible conflicts. Root, for example, is a member of the admins group. To avoid conflicts, you must not set the privileges for root to read only, while admins is set to writeable.

In the event of conflicts in access privileges, the system will authorize users/groups in the following order: no access (N/A), readable and writeable (RW) and read-only (RO). For example, if the access privilege of the root account (belonging to the admins group) is set as

“N/A” and that of the admins groups is “RW,” the access privilege of root for this folder will be “N/A.” If the privilege for everyone is set to writeable and the user root to read only, the system

will assign writeable privileges to everyone as soon as you click “Apply”.

2. The NAS server supports the ACL (Access Control List), i.e. users can click the right mouse

button on a file and set the access privilege. Please refer to the last section of this chapter Using Access Control List (ACL) for details.

The system administrator can use NAS-5000 Series Manager’s Security SetupàShared Folder Setup page to set the access privileges for every shared folder.

NFS Privileges tab

Use this option to set NFS (Solaris, FreeBSD or Linux and other UNIX family clients) access privileges for shared folders.

Enter the Shared Folder SetupàNFS Privileges page, and select the desired shared folder in the Folder name column. The NFS client’s privilege column below will show the hosts and subnets or net groups with access privileges and the type of permission granted.

NFS client’s privilege consists of three components:

1. The first component is the subject sharing a folder, either a host, subnet, or a net group. The

entry Host:* means the folder is shared between all hosts.

2. The second component is the share mode, such as read only or writeable.

3. The third element is a local user name. The administrator root of a NFS client can only access

the folder with this ID.

The root of some clients and the NAS root can be owned by different users. Unless you wish to manage a shared folder from a client terminal as root, you should always assign the terminal root to a non-root ID for security reasons.

Adding NFS user privileges

To add NFS user privilege settings, click on “Create”. A new page will appear. Enter the “hostname”, “subnet mask” (e.g. 192.168.1.0 / 255.255.255.0), or “net group” (only available if

the NAS server joins the NIS domain). Under “Map client’s root account to” column, choose a local user, and then set the “NFS client’s privilege” to read only or writeable. Click “OK” to confirm your selection and return to the previous page, or click “Next” to add another client.

Note:

When setting user privileges for the NFS hosts, subnets or net groups, try to avoid possible conflicts. E.g., if host A belongs to net group AAA, do not set the access privilege of host A to read only while setting AAA to writeable.

Conflicts will be dealt with in the following manner:

1. If a single host setting conflicts with Host*, the single host setting is used.

2. If a single host setting conflicts with the subnet setting, the single host setting is used.

3. When a single host setting conflicts with a net group, the entity which first received its user privilege has priority. If the net group AAA has already been set to writeable, you cannot later set the single host A to read only.

Deleting NFS User Privileges

To delete the user privileges of a NFS client, select the desired item on “NFS client’s privilege” column (use Ctrl for multiple and Shift for continuous selection), and click “Remove”.

Modifying NFS User Privileges

To modify existing privileges, select the desired item on “NFS client’s privilege” column, remove it and add a new privilege.

4.3.2 Account Setup

The NAS server supports up to 20480 user accounts (Including accounts on the local machine, Windows, and NIS server). Three types of users can access a NAS server:

1. Local users, with an account on the local machine.

2. Users with Windows domain or Active Directory accounts

3. Users with accounts on a UNIX NIS server

Local Accounts tab

The system administrator can setup accounts for Windows, and Mac users on the NAS server (the local machine). When these clients attempt to access the NAS server, they only need to enter their account name and password to gain access.

The system administrator can add, modify and delete user accounts. Account name is not case sensitive. It can be up to 64 characters except for the following characters:

! " # $ % ' ( ) * + , / : ; < = > ? @ [ ] \ ^ ` { } | ~ Besides, the first character cannot be minus sign and space, and the last character cannot be

space. The password is case-sensitive and can consist of 0 to 12 displayable characters, including letters, numbers, signs, and spaces.

Note:

The passwords for some clients, such as Windows 98 clients, are not case-sensitive while the passwords for other clients, such as Win NT/2000, UNIX, and Mac clients are. Therefore, please make sure the account passwords for the local machines are case-sensitive so that they will be suitable for all clients

Mac clients only allow passwords of up to 8 characters. Thus, when setting passwords for Mac 46

clients on the NAS server, please limit the length of passwords to 8 characters or less.

Default local accounts

There are two preset accounts on the server: root and guest.

1. root: This is the default account for the system administrator and belongs to both the admins and users group. As a first step in the server setup, please setup a password for this account.

2. guest: This open account belongs to the guests group and has no password and quota restriction by default. Its purpose is to give access to all users on the LAN, so that they may access the NAS server’s guest folders, such as publicn. For the unauthorized Windows 98 clients, the system will automatically connect them to server with the account guest. For other Windows NT/2000/XP, and Mac clients, users can enter guest as the user name (no password is needed) to connect to the server..

However, due to security reasons, the system administrator might not want all unauthorized users, e.g. users without an account on the NAS server or other account servers on the same LAN, to access the shared folders of the NAS server. By adding a password to the guest account, unrestricted access is disabled.

Note: Account server, e.g. a Windows domain controller on an NT domain, Windows 2000 Active Directory Service or a NIS server on a UNIX domain.

Adding user accounts

To add a new local user, click “Create”. The “New Account Setup” dialog appears. Enter the “account name”, the “full name” of the user, an e-mail address and a password. Under “Default group”, select whether the user will receive his/her own home folder. If yes, select the “users” group; if no, select “guests”.

After a new account has been created under “users” group, the system will set up a home folder named “home” for this account. Only the user can access his home folder. If a Windows client accesses the NAS server through the Network Neighborhood, he will see a folder named “home.” The user has full read and write privileges to that folder. When the system has more than one volume, system administrator must specify in which volume to store the home folder of this account in the “User home volume”. The default location can be setup in the “Security Option” page. System administrator can also change it.

The system administrator can proceed to setup the disk quota for each account. The default quota for newly created user specified in the “Security Option” page will be displayed here. Please change it according to your own need. Please note the disk quota will be applied to every volume. This means that if there are three volumes in the NAS server, and system administrator grants 100MB quota to a user, this user will have 100MB quota of storage space in each volume, and totally 300 MB quota on the NAS server.

Note:

If the quota set by the administrator for a new account differs from the default quota granted to the user in the “Default Privilege Settings” page, the user quota on future created volumes will be based on that in the “Default Privilege Settings” page. Thus the administrator must change the quota manually.

The preset value for the guest and root accounts is unrestricted. If, for security reasons, the administrator wishes to restrict disk quota for guest users without proper accounts on the NAS server or any account server, simply setup a quota for the guest account in the Security SetupàQuota Option page. The system administrator can also use this page to change the quota of each account or specify quota in each volume of a user in a flexible way. .

When a Windows NT 4.0/2000, or Mac user accesses the NAS server, the Windows operating system will ask for the NAS server or Windows account and password to confirm his or her identity. In the case of Windows 98, Windows will automatically retrieve the identity of the client and only request a password. If the Windows user account is not the same as the account on the NAS server, the client cannot log in on the server. The system administrator must therefore keep the NAS server accounts and Windows accounts synchronized.

Deleting local users

To delete a local user, simple select the account on the left side (use Ctrl for multiple and Shift for continuous selection), then click “Remove”.

Modify user account detail

To modify the details of a user account, select an account from the user list on the left side of the page, make changes on the right, and click the “Apply” button below.

Windows Domain Accounts tab

If a Windows domain exists in the network, the system administrator only has to add the NAS server to the Windows domain to take advantage of the Windows domain controller privilege settings and grant all accounts on the Windows domain access right to the NAS server’s storage space. When these clients need to access the server, they can do so by entering their Windows domain account name and password.

Once the NAS server is joining into a Windows domain, a new tab called “Windows domain accounts” will become available on this page, containing a copy of all user accounts. Only the account names will be copied here, without passwords and other information. When a client attempts to access the NAS server, the server will forward the account and password information to the Windows domain for verification. If the user passes the authentication, access will be granted. If the Windows domain controller does not authorize the user, the account is verified against the list of local users. Access is granted, if the login data corresponds to a local user. If a user has an account “user1” on both the Windows domain and the NAS server, but with different passwords, access is granted if either one of the two passwords is provided. The system administrator should, however, avoid allowing accounts existing on the Windows domain to be created on the NAS server. A situation where different users share the same account name should also be avoided.

The NAS server will read the Windows domain account list every 60 minutes; any changes on the Windows domain will also appear on the NAS server.

By default, Windows domain accounts do not have home folders. If you wish to assign a home folder to this type of account, simply select the desired account on the left (use Ctrl for multiple and Shift for continuous selection), then click on “Add to local”. The selected accounts will appear in the list of local users. By default, they are part of the “guests” group. First setup the passwords for the accounts, then transfer these accounts from the “guests” group to the “users” group, and select the “User home volume” location.

Additionally, Windows domain account will directly apply the default settings for all newly created users defined in “Security Option”. The system administrator can setup hard disk quota for each individual NT domain account in “Quota Option”.

Note:

1. For security reasons, the Windows domain does not allow other domains to retrieve the user passwords on it; when the account information in the “Windows domain accounts” tab are added to the “local accounts”, the system will not able to duplicate the user passwords on Windows domain directly to the local machine. The system administrator will have to add passwords for these accounts on the “Local accounts” tab manually. Therefore, please set the same passwords here as the ones on Windows domain.

2. This system allows group names with a maximum of 15 displayable characters. After having been added to a Windows domain, any group name on the domain with more than 15 characters will not be duplicated by the system onto the NAS server. Only one warning message will be shown and inform the system administrator of all unduplicated accounts. If the NAS server is part of the Windows domain, the system administrator has to avoid adding any group on the domain with a name exceeding 15 characters, otherwise the system will not be able to duplicate this group to the NAS server, nor will a warning message appear.

UNIX NIS Accounts tab

If the network already contains a UNIX NIS domain, the system administrator can simply add the NAS server to the UNIX NIS domain to retrieve access settings from the NIS server.

Once the system administrator adds the NAS server to a UNIX NIS domain (see Network SetupàUNIX NIS), a new tab entitled “UNIX NIS Accounts” will appear on this page, containing all the users retrieved from the NIS server. These accounts will directly apply the default quota set up for a new user in the “Security Option” page. The system administrator can also set hard disk quota individually for each NIS domain account in the “Quota Option” page.

When adding new users In some UNIX platforms, the system allows creating an according group with the same name, and since the NAS server only allows up to 1,024 user groups, it is suggested you don’t create the according groups when creating new users in the UNIX platform to avoid failure of the NAS server adding to the NIS domain.

4.3.3 Group Setup

User Group tab

Use this page to add, modify or delete user groups. NAS server allows up to 2048 user groups (including user groups on the local machine, Windows domain and NIS server).

Group name is not case sensitive. It can be up to 15 characters except for the following characters:

! " # $ % ' ( ) * + , / : ; < = > ? @ [ ] \ ^ ` { } | ~ Besides, the first character cannot be minus sign and space, and the last character cannot be

spaces.

Default user groups

The system includes three default groups:

1. admins: this is the system administrator group. Only members of this group can change system settings. “root” is the default member of this group.

2. users: this is the user group. Each member of this group has his/her own home folder. “root” is

the default member of this group.

3. guests: unlike the members of the “users” group, those of “guests” do not have their own home folders, instead, they can access the public folders on the NAS server. The account

“guest” is the default member of this group.

Note: Users can only belong to either the “users” or the “guests” group, not to both. Suppose a

company has two departments A and B. Department A has purchased a NAS server for their employees to store and share information. Part of the space should be made available to department B. In this case, the system administrator can setup accounts for each member of department A and B, then group the department A accounts under “users” and the members of department B under “guests”. That way the employees of department A will have their own home folders, while the members of department B will be able to access only those folders for which they have access privileges.

Adding user groups

To add a new group, click “Create”. The “New Group Setup” page appears. Enter a name for the

group, and select the members of the group in the “Not members” list (use Ctrl for multiple and Shift for continuous selection). Click on “Add” to add the selected members. Select “OK” to confirm the operation, or “Next” to add more groups.

Deleting user groups

To delete a group, select the group in the list (use Ctrl for multiple and Shift for continuous selection), and then click “Remove”.

Group members tab

Use this page to add, modify, and delete group members. The “Members” field contains existing members. Users not belonging to this group are listed on the left “Not members” field.

If this NAS server belongs to a Windows domain and (1) the system administrator has previously moved Windows domain users in the “Account Setup” page to the local accounts or (2) both NAS server and Windows domain have the account with the same name, those NT domain users will NOT appear in the list of members but Local Users to avoid multiple selection and assignment to a group of the same user.

Adding group members

To:

To add a new group member, select the target group from the list, and then select the members you wish to add in the “Not members” list (use Ctrl for multiple and Shift for continuous selection). Then click “Add”.

Note that all users must belong either to the “users” or the “guests” group. If the system administrator uses this page to move a member from the “guests” group to the “users” group, the account will automatically be removed from the “guests” group, and vice versa. However, accounts belonging to “guests” or “users” group can be assigned to other groups, including the predefined “admins” group, or any other group set up by the administrator.

Deleting group members

To remove a member from a group, select the name from the list of members (use Ctrl for multiple and Shift for continuous selection), then click “Remove”.

Note: If a user is connected to the server while the administrator is modifying the user’s security settings, these changes will not be applied immediately, but only after the user logs out and back in again.

Moving group members

To move a user account to another group, you should delete this account from the original group and then add it to the new group.

Rules for moving group members as follows:

guests users admins

From:

guests Allowed Not allowed Users Allowed Allowed admins Not allowed Allowed

Note: Moving an account from the “users” to the “guests” group will remove the home folder of that account, as well as its data. Be careful in making this change.

Although the “root” account belongs to both the “admins” and the “users” group, there is no home folder for this account. Moreover, the system administrator cannot move “root” account into the “guests” group. The “guest” account can only belong to the “guests” group. The system administrator cannot move it to the “users” or “admins” group.

4.3.4 Quota Option

User quota tab

You can modify user quota on this page. Please follow the steps below to modify user quota:

1. Select the user account you want to modify in the “User Name:” pull down menu.

2. Select the volume item to be changed in the “Current [In Use/Quota](MB):” list.

3. In “Setting New Quota:” either enter new quota or select “unrestricted.”

4. Click the “Set>>” button, and repeat the steps above if there are more than one volume item to setup.

5. If you want to cancel any setting, select the item form the “New Quota(MB):” list, and click the “<<Cancel” button.

6. Click “Apply” to confirm.

Note: The “Current [In Use／Quota] (MB)” list indicates the quota and the space used in each volume by the current account. The symbol "*" in this list means the account is assigned the

maximum quota.

Volume quota tab

You can modify user quota in every volume on this page. Please follow the steps to modify volume quota:

1. Select a volume in the “Volume quota.” pull down menu.

2. Select the user account to be modified in the “Current [In Use/Quota](MB):” list.

3. In “Setting New Quota:” either enter new quota or select “unrestricted.”

4. Click the “Set>>” button, and repeat the steps above if there are more than one volume item to setup.

5. If you want to cancel any setting, select the item form the “New Quota(MB):” list, and click the

“<<Cancel” button.

6. Click “Apply” to confirm.

Note: Please note that the setting will be separated into different pages according to the number of accounts. If the account you are going to perform does not appear on the page, please select the page number at the bottom of the page to go to other page

4.3.5 Security Options

The system administrator can use this page to modify the preferences of newly created shared folders and user accounts.

Default settings for newly created folders

1. Privileges for everyone: ○ writeable ○ read-only ○ no access

New folders can be exported to Windows/Mac either with full read and write permissions, i.e. writeable, with write protection, i.e. read-only, or no access right, i.e. no access.

2. NFS exported as:○ writeable ○ read-only ○ no access

This setting determines whether NFS users have by default full read and write permissions, i.e. writeable, can only read newly created folders, i.e. read-only, or no access right, i.e. no access.

Default settings for newly created accounts

1. Default group: ○ users ○ guests

Here you can choose to which group newly created users belong by default. If you want new accounts to automatically have a home folder, choose “users”, otherwise, choose “guests”.

2. Default quota: ○ MB ○ unrestricted

With this setting you can limit the amount of storage space allotted to new users, or choose not to attach any restrictions, i.e. unrestricted.

3. Default home volume: Volume If the newly created account belongs to “Users” group, please select the volume in which its home

folder will be saved. Note: If a user is online, all the user privilege changes under “System privileges setting” will not

be effective at once but only after the user has logoff and login again.

4.3.6 Using Access Control List (ACL)

The NAS server allows users of different platforms to access the files simultaneously. However, different platforms themselves have different design of the access right control for files and folders. The ACL implements an appropriate mapping among platforms to provide consistent behavior of file level access control.

4.4 Network Setup

Use this section to set the network types supported by the NAS server. The default setting allows for simultaneous use of Windows, UNIX, and Mac networks. You may change the defaults according to your needs.

4.4.1 Windows Network

The system administrator can choose to enable Windows networking so that the Windows clients can access the shared folders of the NAS server. To do so, select “Enable Windows networking”, and then select “Workgroup” or “Domain” below.

If “Workgroup” is selected, type the workgroup name and then press “Apply”. If “Domain” is selected, type the Windows domain name in the “Domain:” field, in the “Account

name:” and “Password:” fields type in the authentication data of the Windows account that belongs to the Administrator group, and then click “Apply” to complete.

Please note that in the “Domain:” field, you can type a fully qualified domain name (up to 63 characters) or NetBIOS domain name (up to 15 bytes).

Applying Windows domain Privilege Settings

After the server has successfully joined in a Windows domain, a new tab will appear on the Security SetupàAccount Setup screen, called “Windows Domain Accounts”, containing a copy of all user accounts. (For setup instructions, see Security SetupàAccount Setup àWindows Domain Accounts).

In the future when a Windows or Mac client attempts to access the NAS server, the server will forward the entered account and password to the Windows domain controller for authentication. If the authentication passes, access right to the NAS server will be granted. However, if the authentication fails, the NAS server will take over the authentication task and grant the user access right if the entered account and password corresponds to a local user.

Note:

1. After moving a NAS server from a Windows domain, or workgroup to another domain or

workgroup, the NAS server may still appear in the original domain or group in the Windows clients’ My Network Places. This is a restriction of the My Network Places module itself and does not involve a breach of security: the server does in fact not exist any longer in the original domain or workgroup.

2. When NAS server is added into the Windows domain, if Windows domain controller is not able

to operate properly, Windows client users will not be able to access the NAS server. This is the limitation of Windows. Setting multiple Windows domain controllers can eliminate the chance of happening.

3. For security reasons, an existing root account on the Windows domain will not be merged with

the root account of the NAS server. In other words, if a client attempts to log into the NAS server with the root account, he must enter the NAS root password to gain access as system administrator.

4. Once a NAS server is part of a domain, only users in the same Windows domain can access

the server. Members of other domains or workgroup cannot access the server. E.g., if your NAS server is part of a Windows domain A, and the Windows in this domain knows an account user1 with the password 123. If the client to which this account belongs to another domain B, the client will still not be able to access to NAS server, even when providing the correct login information on the account.

Synchronization settings

After the NAS server successfully joins in the Windows domain, there will be an additional tab named “Synchronization settings” appearing next to the existing tab “Windows Network”. In this

page you can setup how the user and group data of the NAS server will be synchronized with the Windows domain controller.

Synchronize with schedule

You can choose to synchronize data between the NAS server and the Windows domain controller every fixed period or at a certain time everyday. To do so, select an appropriate time from the pull-down menus and then click the “Apply” button to finish the setting.

Please note that when the account number is large, to ensure every scheduled synchronization can complete and to keep the server efficiency, the interval between 2 synchronizations should not be too long.

Synchronize immediately

Select the check box before the option “Synchronize immediately” and then click “Apply”, the NAS server will synchronize data with Windows domain controller right away.

WINS Server

If there is a WINS server in the Windows network, please fill in the IP address of the WINS server.

4.4.2 UNIX Network

The system administrator can decide whether to make the NAS server available for NFS client. If yes, please select “Enable UNIX Networking”.

If there is a NIS server in the UNIX network, use this option to select whether the server should be part of a NIS domain. If yes, you must enter a domain name.

After joining a NIS domain, a new tab called “UNIX NIS Accounts” will appear under Security SetupàAccount Setup, showing all available user accounts on the NIS server. System administrator can setup hard disk quota for these users in the Security Setupà Quota Option page.

4.4.3 Apple Network

Use this option to select whether the server should use AppleTalk or TCP/IP, thus allowing or preventing Mac clients from accessing the NAS server.

This system also supports "Zone", a logical group of devices in an AppleTalk network. When the system detects the first subnet that has an AppleTalk Zone, it will display these zones on this page. A system administrator can add the NAS server to one of the zones.

Note:

1. If the NAS server is set up as having multiple subnets, this system only supports Mac client in

one single subnet to read/write from the server through AppleTalk or TCP/IP protocol. Mac clients in another subnet can only read/write through TCP/IP protocol. Due to this limitation, this system can only support the Zone in a single subnet.

2. When a Mac client, for example a Mac OS 9.0.2 client, is trying to browse an English web site

and sees many “cross” marks appear, please close “Smartview” from the “Control Panel”.

3. Mac clients will not be able to save any single file larger than 2GB onto the NAS server.

4. When a Mac client deletes a file on the NAS server, the file is not actually deleted. So the 70

available HDD space shown on the “Server Information/Status” page is not enlarged. To release the space, use “Empty Trash” on the Mac client.

4.4.4 Internet Network Internet Network tab

The system administrator can make Internet related configurations on this page.

Automatically browse Storage Manager with HTTPS

HTTPS is a protocol encrypted with SSL that makes data transmission between clients and the server more secure.

To automatically browser the “Automatically browse Storage Manager with HTTPS”, and all HTTP connections will be redirected to HTTPS.

NAS-5000 Series Manager

with HTTPS, check the option

Enable FTP service

FTP is a network protocol that allows user to transfer files between clients and server. For security reasons, “root” account and other accounts without password configured are not allowed to access NAS server via FTP.

Enable SSH service

SSH service is currently available only for the system vendor to do remote diagnosis.

Connection Security tab

This page allows administrators to define the FTP access privileges. Select “FTP” in the “Connection Type”, then enter appropriate information in “Hostname” or “Subnet/Mask” fields.

Select “Allow” or “Deny” from “Access privileges”, then click “Create” to add this record. After all privileges are set, click “Apply” button to save the configuration.

4.5 Volume Management

The system administrator can add or delete volumes in the system according to his/her own needs.

4.5.1 Volume Setting

System administrator can change, remove, or repair volume on this page without restarting the server for the setting to take effect.

Create volume

1. Click on “Create” button to create a new volume and select the “Volume Type” you want to create. There are six available options for NAS-5400 in “Volume Type” field.

Simple The NAS server will create an independent volume on each available hard disk with its

available capacity, and the volume does not have data redundant mechanism. Span

Select this option to make the selected disks as a concatenated, single volume.

RAID 0 A RAID 0 volume takes all hard disk for one large hard disk, and performs parallel and

multiple read and write, thus it has better performance than Non-RAID volume. RAID 0 volume is applicable for severs with two hard disks, and the hard disks must be identical in size. If 2 different capacity hard disks are chosen to create a RAID 0 volume, the capacity of the smaller one will be adopted to create the volume.

RAID 1 A RAID 1 volume duplicates data from one hard disk to another to ensure data security

and integrity. The actual available space is only half of the total space. This level of RAID ensures high level of data security, but because it only has 50% utilization rate, the cost is relatively higher than other volume types. RAID 1 volume is applicable for severs with two hard disks, and the hard disks must be identical in size. If 2 different capacity hard disks are chosen to create a RAID 1 volume, the capacity of the smaller one will be adopted to create the volume.

RAID 5 This configuration includes a backup option. It treats multiple disks as one virtual disk to

increase access speed. It uses parity mode to store redundant data on a space equal to the size of one disk for later data recovery. The actual available storage space in a system with n disks is thus n-1 hard disks.

RAID 5 with Spare RAID 5 with Spare adds one spare disk to the RAID 5 array, allocating one for redundancy

and the second one as a spare. The actual available storage space in a system with n disks is thus n-2 hard disks.

2. If you choose to create a RAID 1, RAID 5, or RAID 5 with Spare volume, you must specify which option you want the consistency or parity data of the volume to be created. The volume will be available for access in a short time when consistency or parity is built in the background. If the consistency of parity is built in the foreground, all processes must be finished before the volume can be accessed.

3. The “Available Space (GB):” list indicates space in each hard disk that has not yet been allocated. Please determine which hard disk storage space will make up the volume.

4. Select the size from the “Size to use:” pull down menu.

5. Click the “Add>>” button.

6. Repeat step 4 to step 6, or press “Ctrl” fro multiple selections or “Shift” for continuous selections in step 4.

7. Click “OK” to confirm and start creating the volume. After a volume is created, the default publicn shared folder will also be created. You can now

create shared folders in this volume and grant access right to the client users.

Note:

1. “Size to use” is measured in the unit of “GB,” i.e., gigabyte, and the smallest unit is decided by

dividing the size of the hard disk by 20 to get the nearest whole number. For example, if the size of a hard disk is less than 40 GB, the smallest unit is 1GB, while the size of the hard disk is greater than or equal to 40GB and less than 60GB, the smallest unit is 2 GB, etc.

2. Regardless of the hard disk size, the option “1GB” will always be shown in the “Size to use:”

menu.

3. The size of a single volume can be up to 8 TB.

4. After a volume is created, the “In Use:” size will reveal 1% of that volume. This space is

reserved by default for the administrator to do the necessary operations such as accessing the web UI or reading/writing/deleting data on the NAS server after the system is full.

Re-create volume

If a volume is crashed due to any failed disk, the volume structure could be recovered by clicking the “Re-create” button.

The re-creating function can only re-create the original structure of the crashed volume: share folders and users’ home folders, and set it as the default volume if it originally was setup as such. It cannot restore any lost data in these shared folders.

Before you start recreating, please make sure the failed disk is replaced with a new one.

Note:

1. When a volume crashes, all data in users’ home folders on the crashed volume will also be

destroyed. However, the structure of the folders will be moved to the next available volume, and the original folder structure will be moved back after the crashed volume is re-created.

2. When a volume crashes while there is no other volume available, the data in users’ home

folders on the crashed volume will be destroyed and the users’ accounts will be transferred into the guests group. There will be no home folders for these accounts if the volume is re-created in the future since the accounts in the guests group don’t have a home folder.

Repair volume

For RAID 1 and RAID 5 Volumes

When any of the sub-disks that compose the volume with data protection mechanism, such as

RAID 1 or RAID 5, the status of the volume will become “degrade.” When a volume becomes “degrade,” a “Repair” button will appear on the bottom of the page if

there is available hard disk space on the hard disks that don’t compose the degraded volume, and you can follow the steps below to repair the volume:

1. Click “Repair”.

2. Choose the hard disk space to be used in the “Available Space” list.

3. Click the “Add>>” button.

4. Click “Repair” to confirm.

Note:

1. To ensure the data protection mechanism still provides the highest level of safety, you can only

select the hard disk on which the volume is not created while repairing volume space.

2. If there is no available hard disk space on the NAS server when a volume becomes “degrade”

status, please replace the bad hard disk that makes the volume “degrade,” and the NAS server will repair the volume automatically after the new hard disk is inserted

For RAID 5 with Spare Volume

When the spare sub-disk fails

When the spare sub-disk that compose the "RAID 5 with Spare volume fails, the status of the volume will becomes "Spare sub-disk abnormal,” in this case please replace the spare disk for the NAS server to automatically repair the volume.

When the non-spare sub-disk fails When any of the non-spare sub-disks that compose the "RAID 5 with Spare volume fails, the

spare sub-disk will take over the failed sub-disk and repair the volume automatically, and after the repair finishes, the failed sub-disk will becomes the spare sub-disk, and the volume therefore becomes “Spare sub-disk abnormal,” please replace the spare disk in this case

: “Spare sub-disk” stands for a hard disk space on a hard disk that composes the “RAID 5

Note

with Spare” volume, while “spare disk” stands for the hard disk with the “spare sub-disk” on it.

Check file system

If the NAS server is improperly shut down or powered off, consistency check and parity check will be applied on RAID 1, RAID 5, and RAID 5 with Spare volume(s) when the server is rebooted. And if the hard disk is improperly removed on the parity check stage, the “Volume Setting” page will show the following message:

The system has detected that the volume needs file system checking. Press Check to begin the

process.

Please click the “Check” button to start the file system check and recovery. The integrity of file system will decide whether the data on the NAS server is read correctly. Even

though file system check is applied after any improper shutdown, it may still lead to data lost. Hence it is strongly recommended that The NAS server be shut down properly.

4.5.2 Volume Layout

This page shows the status of volume layout in the NAS server.

4.5.3 Cache Setup

Turn on disk write cache support

System administrator can enable or disable the hard disk write cache here. This setup will take effect only if the server hard disk supports cache memory. If the hard disk

write cache is enabled, the system read/write performance will improve, but it may result in data loss if any unanticipated power failure occurs. If the system utilizes UPS, then we suggest that you enable this selection. To check if the hard disk supports the cache memory, contact your hard disk dealer.

Turn on RAID 5 cache support

A RAID 5 volume requires more frequent data requests to compute parity, and to improve the I/O efficiency, the NAS server supports RAID 5 device-layer cache so data can be stored in memory temporarily for faster access.

However, it is suggested UPS is accompanied with the NAS server when this option is turned on to avoid data loss when unanticipated power failure occurs.

Note:

1. You have to reboot the NAS server to make the RAID 5 Cache setting effective, and it will be

applied only to the selected volume(s).

2. If the NAS server doesn’t have any RAID 5 volume when you apply the “Turn on RAID 5 cache

support “option, the RAID cache support will be turned on automatically on all future created RAID 5 volumes.

4.5.4 Home Setup

When adding a new account into the “Users” group, the system will automatically create a home folder for this account. System administrator must specify the volume to store the home folder. But it is possible to save many accounts into certain volume causing the volume to carry heavy load or have inadequate space. This “Home Setup” page enables system administrator to easily manage user home folders.

After selecting a volume in “Volume Name”, the system will display accounts’ home folders in the selected volume in the “Current User (home size)” column. Select accounts that require moving of home folders, select destination in “Move to Volume” and click “Move to”. After confirmation then

click “Apply”.

Note:

1. Administrator cannot move users’ home folders to other volumes when any user is accessing

his/her own data online.

2. The setting will be separated into different pages according to the number of accounts. If the

account you are going to perform does not appear on the page, please select the page number at the bottom of the page to go to other pages.

4.6 Toolkit

4.6.1 LED Management

The first two options are preserved for future use. If there is any system event occurred, the beeper inside the NAS server will keep beeping. You

can turn it off by clicking “Event Reset” button.

4.6.2 SNMP Configuration

Use this option to enable SNMP access. To do this, select “Enable SNMP access” and in the column “System location”, enter the geographical location of the NAS server; then click “Apply”.

Each entry in “Access privileges” consists of three elements:

1. The first component is the community the NAS server belongs to, to be chosen by the system

administrator.

2. The second component is the host or subnet of this community.

3. The third element is the NAS server access privileges of the community’s host or subnet

through SNMP

Adding SNMP Access Privileges

To add SNMP access privileges, click on “Create”. A new screen will appear, where you can select a community name along with the host and Subnet /Mask (e.g. 192.168.1.0/255.255.255.0) belonging to this community. Then select the “Access privileges from SNMP”: either “read only”, or

“writeable”. “Read only” means the community hosts can only read information through SNMP, “writeable” means the community’s hosts can also modify some read and write fields. Click “OK” to confirm or “Next” to add more privileges.

Removing SNMP Access Privileges

To remove SNMP access, select an option under “Access privileges” (use Ctrl for multiple and Shift for continuous selection), and then click “Remove”.

Modifying SNMP Access Privileges

To modify existing privileges, select an option under “Access Privileges”, remove it and add a new privilege.

4.6.3 UPS Management

The NAS server currently supports only APC Smart Series UPS, either via serial connection or SNMP.

Control UPS by serial port

Connect the power cable of NAS server to the UPS and connect APC RS-232 cable to COM port on rear panel of the server. In NAS-5000 Series Manager, go to ToolkitàUPS Management to configure “Probing interval” and “Delayed before shutdown”.

Select “Control UPS by serial port”, and choose “advanced port” or “basic port” from the pull-down menu on the right side. Click “Apply” to finish.

If the power cable of the NAS server and APC RS-232 cable are connected to the UPS directly, select “advanced port”; if more APC RS-232 cables are connected to the expansion unit for multiple servers to share the same UPS and the NAS server has to be connected to the basic port on the expansion unit, select “basic port”.

Note:

1. When APC UPS expansion unit is used, please use the proper APC RS-232 cable to connect. If “advanced port” is selected, make sure that the 940-0024C cable is connected, and if “basic port” is selected, please connect the 940-0020B cable.

2. Advanced port provides automatic response function so that the system will detect when it does not find any UPS. Basic port does not have this function.

The system performs scheduled detection of UPS power supply according to “Probing interval”. The system will take the following actions if there is anything abnormal with UPS:

1. AC power failed: If AC power failed, the system will delay shutdown according to the settings in “Delayed before shutdown”. If the event is cleared during this period, the system will not shut down.

2. Low battery: If UPS battery is low, the system will shut down in five seconds. If the event is cleared during this period, the system will not shut down.

3. Overloaded: If UPS power supply is overloaded, the system will shutdown based on the setting of “Delayed before shutdown”. If the event is cleared during this period, the system will not shut down.

4. When the cable is connected to Advanced port, the system will shut down five seconds after UPS timeout. If the event is cleared during this period, the system will not shut down.

Reboot this server automatically after AC power is restored

If you want the UPS to boot the NAS server automatically when AC power restores, please select the option “Reboot this server automatically after AC power is restored”.

Note: If the option is selected, when AC power fails, the NAS server will shut down based on the setting of “Delayed before shutdown:”, and then the UPS will shut down after 3 minutes. Thus if other machines share the same UPS with the NAS server, they will also lose power when the UPS shuts down, in this case, please properly configure the “Delayed before shutdown:” option of other machines.

Control UPS by SNMP

1. Connect the power cord of the NAS server to the UPS and the UPS to the network. Select

proper values for “Probing interval” and “Delayed before shutdown”.

2. Select “Control UPS by SNMP, using the following settings:”.

3. UPS IP address and UPS community

UPS equipped with SNMP faculties will be assigned an IP address. Enter this IP address in the respective column. In the SNMP user interface of the UPS terminal certain communities will be

registered, each community containing one or more host names and IP addresses. These hosts can be trusted and can read information from the UPS. If you want to control the UPS via SNMP, you must register the NAS server in one of the communities listed, then enter the name of the community in the “UPS community” field.

4. UPS enterprise OID

This setting can be found in the MIB file of the UPS. If the UPS supports SNMP access, the manufacturer has added an MIB file to the documentation. Download the file from the manufacturer’s web site if necessary. Look in the file for the “Private Enterprise Number”. APC’s Private Enterprise Number is 318, so the value of this field should read 1.3.6.1.4.1.318, whereby 1.3.6.1.4.1 is static and must not be changed. You can also use an SNMP program such as HP OpenView to browse through the MIB file and retrieve the “Private Enterprise Number”.

5. Battery Status OID

This setting refers to the “battery status OID” in the MIB file. The value for the APC UPS is

1.3.6.1.4.1.318.1.1.1.2.1.1. Enter this value, or the short form 1.1.1.2.1.1, if you are using an APC product.

6. Normal status

The “battery status OID” (see above) obtained from the MIB file represents a number of states, e.g., 2 for “battery normal”, 1 and 3 for “unknown” or “low battery” respectively.

After items 5 and 6 are filled up, the system will probe the UPS in the interval chosen above and shut down in 5 seconds if abnormal battery status is detected.

7. Registered UPS event trap OID pairs

A UPS with SNMP faculties usually has a trap function, used to detect anomalies in the UPS status without waiting for the scheduled probing signal. Click “Edit trap” to add or delete event trap OIDs for your UPS.

In “Start of event OID”, enter the critical event trap OID. Alternatively, use an SNMP program such as HP OpenView to browse through the MIB file and obtain the trap OID. The value

1.3.6.1.4.1.318.0.5 for example stands for A/C power failed, switching to battery. In the field “End of event OID”, enter the informational trap OID, e.g. 1.3.6.1.4.1.318.0.9 for A/C

power restored. This field is optional, since many critical events do not permit resuming and require a system shutdown. Retrieve both values for “Start of event OID” and “End of event OID” for the MIB documentation of your UPS manufacturer.

Note: After making the configuration above, the system will periodically probe the UPS status based on the “Probing interval”, and shut down in the time as defined in “Delayed before shutdown” when abnormal events defined in “Registered UPS event trap OID pairs” occur.

4.6.4 Restore Defaults

The system administrator has the option to restore factory defaults for all settings, or remove all user settings in the system. Four options are available:

1. Restore Server Configuration (basic, code page, notification).

2. Remove shared folders, and files in home folders.

3. Remove all users, groups, shared folders, users' home folders, and their files.

4. Remove data on the server, including all above.

Note:

1. Be careful when using the options on this page. All selected settings will be replaced by defaults or deleted.

2. If you choose to apply the first (Restore Server Configuration) or the fourth (Remove server) option, you must go through “Quick Configuration” again.

4.6.5 Shutdown/ Restart

Use this page to “Shutdown or Restart” the server. You can also use the power switch on the NAS server. To preserve data integrity, never unplug the server before it has been properly shut down. System administrator can select the option “Delay xxx minutes to shutdown/restart the server” and the setup will be executed after the time specified.

Wait for the power LED to go off and the server to halt operation completely before unplugging and moving the server.

4.6.6 System Update

Once you have obtained the OS upgrade, follow these steps to update your system:

1. Copy the update file (assume its name as “update.pat”) from any client computer to any shared folder in the NAS server.

2. Click “Browse” to select name and path of system update file.

3. Click on “Update”. The update process will start immediately and the system will restart automatically upon completion.

Note:

1. System update will not affect the files saved on the server. However, we still strongly recommend that the administrator backup all the files on the server before updating the system.

2. The server cannot be accessed while the upgrade is running.

3. When the system is being updated, do not close NAS-5000 Series Manager window, turn off the server or remove the AC power, to avoid errors in the system operation.

4. During the upgrade, the browser on the client terminal will loose the connection to the system. Close the browser and wait for the upgrade to complete before re-connecting to NAS server. (The system will send an e-mail message informing the administrator that the server is back on line).

4.7 File Browser

This function allows users to have remote access to files in the server through the Internet (HTTP protocol). The user can login to NAS server and browse all the folders and files in each shared folder the user has access rights.

Note: To make sure files/folders on the NAS server can be displayed correctly on this page, please upgrade the IE browser version to 5.5 or above.

4.8 Logout

For security reasons, remember to log out whenever you complete the management operation.

Chapter 5

Using Backup Utility

PLANET NAS-5000 series Backup is a backup tool integrated in PLANET NAS-5000 series Assistant. The system administrator can use it to backup data from the NAS server to other storage devices on the LAN, or to restore previously backed up data back to the NAS server.

There are four types of data available for the administrator to backup and restore:

1. System information: including basic configuration, network time synchronization, time zone setup, language setup, notification setup, security option, Apple network, Internet network, SNMP configuration, UPS management, and cache setup.

2. User accounts and groups: including account and group setup, root password, Windows network, and UNIX network.

3. User accounts, groups, and data: including shared folder setup, account and group setup, root password, Windows network, UNIX network, and data on selected shared folders and user home folders.

4. System information, user accounts, groups and data: all data on the server, including the configurations and data mentioned above.

5.1 Backing up data

To backup data, follow the steps:

1. Activate PLANET NAS-5000 series Assistant, click the NAS-5000 series Backup tab, and select the server to be backed up from the server list, or select “Input server IP manually” and input the server IP.

2. Click on the “Backup” button to open the backup window.

3. Enter the “System administrator password”.

4. Click the “Browse” button to choose the backup path. By default the backup file is named as

“server_name-mmddhhss.bkp”, where mmddhhss stands for month-day-hour-minute of the backup time. The administrator can also specify the file name manually.

5. Choose the backup item from the “What to backup:” list.

If the 3rd or 4th item is selected, an additional option “Backup modified files only” is available for the administrator to choose.
