1.2 Product Description
IFS Industrial Managed Switch is specially designed to build a full Gigabit backbone to transmit reliable and high speed data in
heavy industrial demanding en v ir onme nt s a nd forward data to remote network throu gh fiber optic. It comes with an IP30 rugged
case and redundant power sy s tem. Besides support for 40Gb p s sw itch fa br ic t o han dle extremely large amounts of video, v oice
and important data in a secure topology, the Industrial Managed Switch provides user-friendly but advanced IPv6/ IPv4
management interfaces and abundant L2/L4 switching functions. It is the best investment for expanding industrial business or
upgrading its network infrastructure.
Redundant Ring, Fast Recovery for Critical Network Appli ca tions
The Industrial M anaged S witch supports redundant ring te chnology and fea ture s strong, rapid self-recovery cap ability to p rev ent
interruptions and external intrusions. It incorporates advanced ITU-T G.8032 ERPS (Ethernet Ring Protection Switching)
technology, Spanning Tree Protocol (802.1s MSTP), and redundant power input system into customer’s industrial automation
network to enhance system reliability and uptime in harsh factory environments. In certain simple Ring network, the recovery
time of data link can be as fast as 20ms.
Environmentally Hardened Design
With IP30 aluminum industrial case protection, the Industrial Managed Switch provides a high level of immunity against
electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curb side traffic control
cabinets. It also possesses an integrated power supply source with wide range of voltages for worldwide high availability
applications requiring dual or backup power inputs. Being able to operate under the temperature range from -40 to 75 degrees
C, the Industrial Managed Switch can be placed in almost any difficult environment.
Digital Input and Digital Output for External Alarm
The Industrial Managed Switch sup ports Digital Input and Digit al Output on its upper panel. The external alarm enables users to
use Digital Input to det ect external device’s status (such a s d oor intrusion detector), and send event al ar m to t he ad mi nis t r ators .
The Digital Output could be used to alarm the administrators if the Industrial Managed Switch port is link-down, link-up or
power-dead.
NS3552-16P-2T-2S User Manual 9
Intelligent Powered Device Alive Check
The Industrial Managed PoE Switch can be configured to monitor connected PD (Powered Device) status in real-time via ping
action. Once the PD stops working and responding, the Industrial Managed PoE Switch will recycle the PoE port power and
bring the PD back to work. It will greatly enhance the network reliability through the PoE port resetting the PD’s power source
and reduce administrator managem ent bur de n.

3.3 CLI Mode Management
There are two ways for CLI mode management, one is remot e teln et and the other operated from consol e port. Remote telnet is
an IP-based protocol and console port is for user to operate the Industrial Managed Switch locally only; however, their
operations are the same.
The command line user interface is for performing system administration, such as displaying statistics or changing option
settings. When this method is used, you can access the Industrial Managed Switch remote telnet interface from personal
computer, or workstation in the same Ethernet environment as long as you know the current IP address of the Industrial
Managed Switch.
Direct Access
Direct access to the administration console is achieved by directly connecting a terminal or a PC equipped with a
terminal-emulation program (such as HyperTerminal, ProcommPlus, putty, tera term) to the Managed Switch con sol e (se rial)
port. When using this manage ment met hod, a straight DB9 RS-232 cable is required to connect the switch to the PC. After
making this connection, configure the terminal-emulation program to use the following parameters:
The default parameters are:
115200 bps baud rate
8 data bit s
No parity
1 stop bit
42 NS3552-16P-2T-2S User Manual
You can change these settings, if desired, after you log on. This management method is often preferred because you can
remain connected and monitor the system during system reboots. Also, certain error messages are sent to the serial port,
regardless of the interface through which the associated action was initiated. A Macintosh or PC attachment can use any
terminal-emulation program for connect ing to th e ter minal serial port . A workstation at t achment under U NIX can use a n emu lator
Remote Telnet
In Windows system, you may click “Start” and then choose “Accessories”and “Command Prompt”. Please input “telnet

3.4 Web Management
The Industrial Managed Switch offers management features that allow users to manage the Industrial Managed Switch from
anywhere on the network through a standard browser such as Microsoft Internet Explorer. After you set up your IP address for
the Industrial Managed Switch, you can ac ces s the Industrial Managed Switch’s Web interface applications directly in your
Web browser by entering the IP address of the Industrial Managed Switch.
Figure 3-3: Web Management
You can then use your Web browser to list and manage the Industrial Managed Switch configuration par a meter s fr om one
central location; the Web Management requires Microsoft Internet Explorer 8.0 or later .

3.5 SNMP-based Network Management
You can use an external SNMP-based application to configure and manage the Industrial Managed Switch, such as SNMP
Network Manager, HP Openview Network Node Management (NNM) or What’s Up Gold. This management method requires
the SNMP agent on the Industrial Managed Switch and the SNM P Netw ork M anagement Station to use the same com munity
string. This management method, in fact, uses two community strings: the get community string and the set community
string.
If the SNMP Network Management Station only knows the set community string, it can read and write to the MIBs. However, if it
only knows the get community string, it can only read MIBs. The default gets and sets community strings for the Industrial
Managed Switch are public.

This section introduces the configuration and functions of the Web-based management.
About Web-based Management
The Industrial Managed Switch offers management feature s that allow users to manage the Industrial Managed Switch from
anywhere on the network through a standard browser such as Microsoft Internet Explorer.
The Web-based Management supports Internet Explorer 8.0. It is based on Java Applets with an aim to reducing network
bandwidth consumption, enha ncing access speed and pres e nt ing an easy viewing screen.
By default, IE7.0 or later version does not allow Java Applets to open sock
explicitly modify the browser setting to enable Java Applets to use network ports.
The Industrial Managed Switch can be configured through an Ethernet connection, making sure the manager PC must be set
on same the IP subnet address with the Industrial Managed Switch.
For example, the default IP address of the Industrial Managed Switch is 192.168.0.100, then the manager PC should be set
at 192.168.0.x (where x is a number between 1 and 254, except 100), and the default subnet mask is 255.255.255.0.
If you have changed the default IP address of the Industrial Managed Switch to 192.168.1.1 with subnet mask 255.255.255.0
via console, then the manager PC should be set at 192.168.1.x (where x is a number between 2 and 254) to do the related
configuration on manager PC.
