3 Installation Procedure
3.1 Installation Flowchart
Figure 3-1 Installation flowchart

NSFOCUS NTA Installation Guide
Copyright © NSFOCUS 11 V4.5R90F02 (2020-02-28)
3.2 Connecting to the Power Supply
The AC input voltage of NTA is 100–240 V. Before connection, make sure that the power
supply specifications of the equipment room are the same as those required by the product,
preventing product damage.
To connect the AC power cable, perform the following steps:
Step 1 Turn the power switch of the AC power module to the OFF position.
Step 2 Connect one end of a power cable to the port of the AC power module.
Step 3 Connect the other end of the power cable to an external AC power socket.
----End
3.3 Connecting to the Network
Connect NTA to the network according to the actual network structure.
Pay attention to the following during the connection:
 Use the straight-through cables to connect the switch to the communication interface of
the device.
 NTA can be deployed anywhere in the network. However, to achieve the optimal
performance, it is recommended that you connect it to the switch on the backbone
network of the company.
 After deployment, adapt its network settings immediately to the actual network
environment. For details on default parameters of NTA, see appendix A Default
Parameters.
You can modify network settings on the console-based manager or web-based manager.
For details, see the NSFOCUS NTA User Guide.
3.4 Shutting Down the Device
Shut down the device in either of the following ways:
1. Turn the power supply switch to the OFF position.
2. Log in to the console, type the enable command to switch to the privileged view mode,
and then type the poweroff command. For details about how to log in to the console, see
4.1 Logging In to the Console.

4 Basic Configuration
This chapter describes mandatory configurations for initial login:
 Log in to the console.
 Set the IP address of the management interface.
 Set a subnet mask to log in to the web-based manager and change the initial password.
 Import a valid license file.
4.1 Logging In to the Console
For initial use, you need to log in to the console to change the IP address of the management
interface.
Before logging in to NTA using a serial connection, prepare the following:
 One PC
 One serial cable shipped in the accessory kit
 Terminal software that can connect to the console port, such as the HyperTerminal that
comes with Windows operating systems
 NTA connected to the PC with the serial cable
The following takes HyperTerminal (Windows XP) as an example to detail how to access the
console user interface of NTA:
Step 1 Choose Start > All Programs > Accessories > Communications > HyperTerminal.
The Connection Description dialog box appears, as shown in Figure 4-1.

4.3 Logging In to the Web-based Manager
 Before login, check whether Block pop-ups is selected or JavaScript is disabled in
the browser. If yes, uncheck the selection.
 You are advised to use the latest Firefox, IE 10.0, or Chrome browser and set the
browser resolution to 1024 x 768 or higher.
For the first login to the web-based manager of NTA, perform the following steps (Microsoft
Internet Explorer is used as an example):
Step 1 Make sure that the client communicates properly with NTA (open port 443 if the traffic needs
to go through a firewall).
Step 2 Open the IE browser and connect to the management IP address of NTA over HTTPS, for
example, enter https://10.30.2.204 in the address bar.
A security alert appears, as shown in Figure 4-7.
