CHAPTER 1
Getting to Know Your NSA-2400
This chapter introduces the main features and applications of the NSA-2400 (Network Storage
Appliance).
1.1 NSA-2400 Overview
The NSA-2400 is a device for storing and sharing data that connects directly to your network
via a Gigabit Ethernet port.
Its SATA-I (Serial Advanced Technology Attachment) hard disk serial links are compatible
with all major hard drive manufacturers.
You can expand storage capacity by attaching compatible USB (2.0) drives to the USB ports.
Configure RAID (Redundant Array of Independent Disks) on your NSA-2400 so as your data
is still protected even if one hard disk fails.
You can also protect your valuable data by using the snapshot and backup features on the
NSA-2400.
Note: See the specifications appendix for more detailed information on all features of
the NSA-2400.
The next figure shows an example application for the NSA-2400 in a small office network.
AD is an Active Directory that contains the user names and passwords of all users that are
allowed access to the NSA-2400. Users (U1, U2, U3) can all back up and share data on the
NSA-2400. Important data stored on servers S1 and S2 may be also stored there. In addition to
its internal drives, the NSA-2400 can also extend its storage capacity
It is recommended that the NSA-2400 is placed behind a firewall and/or IDP device to protect
it.

CHAPTER 2
Introducing the Web
Configurator
This chapter describes how to access the NSA-2400 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-2400
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.
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-2400 Web Configurator
Make sure your NSA-2400 is properly connected and that your computer is in the same subnet
as the NSA-2400 (refer to the Quick Start Guide or the appendices).
2.2.1 Access the NSA-2400 Via NDU
If you don’t know the IP address of the NSA-2400, then use the NDU to find it. Refer to the
Quick Start Guide to see how to install and run the NDU.
