Getting to Know Your NSA

This chapter introduces the main features and applications of the NSA (Network Storage
Appliance).

Note: Snapshot and RAID 0 are not supported by the NSA in the first release, but

they are included here as they will be supported in a later release.

1.1 NSA Overview

An NSA is an optimized system for storing and sharing data. The NSA-2400 has its own
operating system, integrated hardware and software, and connects directly to your network to
provide file-level access to data.

CHAPTER 1

It supports SATA-1 compatible (Serial Advanced Technology Attachment) hard disk serial
links, and RAID (Redundant Array of Independent Disks) file storage systems. If configured
in fault-tolerant RAID 1 or 5 mode, your data is still protected even if one hard disk fails.

You can also expand capacity by attaching compatible USB (version 2) drives to the USB
ports.

The appliance also comes with a Gigabit Ethernet port to ensure maximum-speed file access
and backup over your network.

See the appendices for a detailed list of product specifications.

Figure 1 NSA-2400

21 Chapter 1 Getting to Know Your NSA

1.2 NSA Features

This section lists the main physical and firmware features of the NSA.

1.2.1 Physical Features

These are the main external physical features.

Gigabit Ethernet Port

The 10/100/1000 Mbps auto-negotiating Ethernet port allows the NSA to detect the speed of
incoming transmissions and adjust appropriately without manual intervention. It allows data
transfer of either 100 Mbps or 1000 Mbps in either half-duplex or full-duplex mode depending
on your Ethernet network. Use an 8-wire Ethernet cable for Gigabit connections. The port is
also auto-crossover (MDI/MDI-X) meaning it automatically adjusts to either a crossover or
straight-through Ethernet cable.

USB Ports

NSA-2400 User’s Guide

Expand storage capacity by attaching compatible USB (version 2) hard drives to the USB
ports.

SATA Interface

Serial ATA is a low cost interface technology that allows high speed data transfer. Serial ATA
also allows more efficient internal airflow and also smaller chassis design.

Reset Button

If you forget your (admin) password, then use the reset button to restore the factory default
password to “1234” (with user name “admin”), default IP address to 192.168.1.3 and subnet
mask of 255.255.255.0. (Alternatively, you can use the web configurator ‘forget password’
feature.)

BIOS Reset Button

This button is for service personnel only. It is used to reset the BIOS settings to the ZyXEL
default settings in the event the CMOS battery inside the NSA expires. This battery should not
lose power for many years unless there's a battery failure or the NSA has been left powered off
for an extended period of time.

1.2.2 Firmware Features

These are some of the main firmware features of the NSA.

Chapter 1 Getting to Know Your NSA 22

NSA-2400 User’s Guide

RAID File Storage

Use RAID 01 if you want pure write speed and/or maximum capacity for your disks, and/or
you have other means of protecting your data. Use RAID 1 if you have an even number of
disks and want to mirror primary data to another disk(s). Use RAID 5 if you have four disks
and you want to balance performance, hard disk capacity usage with data protection. If one
disk fails, replace it and then re-synchronize to recover all data.

Snapshot

2

A snapshot is a backup of your NSA data on the NSA. If files within a volume become
infected or corrupted, you can revert the volume back to a previous snapshot. It’s a good idea
to create a snapshot before backing up data, to be sure you’re backing up consistent data even
if the backup is still running several hours later.

Disk Quota

Use the disk quota feature to stop one user(s) from using up all disk capacity by setting a limit
on how much storage space he/she may use.

User Passwords

Configure a password for an individual User to restrict access to the NSA. Non-admin users
can change their own passwords by accessing the web configurator. The Change Password
screen appears when a username other than “admin” is entered.

Workgroup and Domain Security Modes

For Windows or Mac OSX users (u sing the Common Internet File System (CIFS) protocol for
remote file access) you can configure Workgroup mode requiring users to log in with a user
name and password. These user and group accounts are maintained on the NSA.

For a large number of CIFS users where accounts are stored on an external server, you can use
Domain security mode (Primary Domain Controller)

Client Support

Data can be shared among all Windows, Mac, Linux, and UNIX users that have FTP client
software or CIFS file sharing support (such as Samba for Linux and UNIX users).

HTTP/HTTPS

Access the NSA using a regular web connection (HTTP) or an encrypted web connection
(HTTPS) using secure socket layer (SSL).

1. Not available at the time of writing.

2. Not available at the time of writing.

23 Chapter 1 Getting to Know Your NSA

NSA-2400 User’s Guide

DHCP (Dynamic Host Configuration Protocol)

DHCP (Dynamic Host Configuration Protocol) allows the NSA to obtain an IP address and
subnet mask at start-up from a centralized DHCP server. Alternatively, you can give the NSA
a static IP address and subnet mask.

Full Network Management

The embedded web configurator is an platform-independent web-based utility that allows you
to easily access the NSA’s management settings.

Firmware Upload and Configuration File Management

Upload new firmware to the NSA using the web configurator. You can also back up and
restore the NSA configuration file containing all its settings to/from your computer.

NSA Discovery Utility (NDU)

Use the NDU from a Windows computer to find NSA(s) in your network, access the NSA
login page, change its IP address configuration or map to a Windows network drive.

Genie Backup Manager

Genie Backup Manager is a tool for Windows users to create (and schedule) backups of data
stored on their Windows computer to an NSA..

Note: The Genie Backup program uses the same network port as the NDU to

discover the NSA. To avoid a port conflict, do not run the Genie Backup at the
same time as the NDU.

Time and Date

Configure a time server and set a time zone for your NSA to show the correct times in e-mail
alerts and logs.

E-mail Alerts

Configure an e-mail to be sent to an NSA administrator whenever an error occurs or as a
scheduled log summary.

Note: See also the specification appendix for more detailed information on this NSA.

1.3 Applications for the NSA

Here are example applications for the NSA in a small home network and in an office network
with a DMZ (DeMilitarized Zone). It is recommended that the NSA is placed behind a firewall
and/or IDP device to protect it.

Chapter 1 Getting to Know Your NSA 24

NSA-2400 User’s Guide

In this small network, the NSA and LAN computers are protected by a firewall.

Introducing the Web

This chapter describes how to access the NSA web configurator and provides an overview of
its screens.

2.1 Web Configurator Overview

The web configurator is an HTML-based management interface that allows easy NSA setup
and management via Internet browser. Use Internet Explorer 6.0, Mozilla firefox 1.0,
Netscape Navigator 7.0 or later versions of these browsers. The recommended screen
resolution is 1024 by 768 pixels or higher.

CHAPTER 2

Configurator

In order to use the web configurator you need to allow:

• Web browser pop-up windows from your device. Web pop-up blocking is enabled by
default in Windows XP SP (Service Pack) 2.

• JavaScripts (enabled by default).

2.2 Accessing the NSA Web Configurator

Make sure your NSA is properly connected and that your computer is in the same subnet as the
NSA (refer to the Quick Start Guide or the appendices).

2.2.1 Access the NSA Via NDU

If you don’t know the IP address of the NSA, then use the NDU to find it. Refer to the Quick
Start Guide to see how to install and run the NDU.

Figure 5 NDU Main Screen

NSA-2400 User’s Guide

From the NDU main page click the icon under Admin to see the web configurator screen login
screen.

2.2.2 Web Browser Access

Open your browser and type in the IP address of the NSA; 192.168.1.3 is the default IP
address if one has not been assigned by a DHCP server.

Figure 6 NDA URL

2.3 Login

The default user name and password are ‘admin’ and ‘1234’ respectively. Enter your user
name and password, then click Login. Non-admin users can change their passwords by using
the username and password assigned to them in the Sharing > Users screen. See Section 4.4.3

on page 54 for details.
