Product Description
Power over Ethernet
The PoE in-line power following the standard IEEE 802.3af and IEEE 802.3at enables the Managed Switch to power up to 24
IEEE 802.3af PoE devices or 11 IEEE 802.3at PoE devices at the distance of up to 100 meters through the 4-pair Cat 5/5e UTP
wire (assuming devices use max limits of these standards; i.e. 15W for 802.3af, and 30W for 802.3at).
Flexibile PoE System Management
Managed Switch not only provides more PoE management function than ever before but also provides better reliability. System
PoE Admin Mode feature offers user to switch PoE system mode between IEEE 802.3af and IEEE 802.3at easily and the
Temperature Threshold and PoE Usage Threshold provides more realiable control.

With its built-in Web-based management, the Managed Switch offers an easy-to-use, platform-independent management and
configuration facility. The Managed Switch supports standard Simple Network Management Protocol (SNMP) and can be
monitored via any standard-based management software.
For efficient management, via WEB interface the Managed Switch can be programmed for basic switch management functions
such as port speed configuration, Port Trunking, VLAN, Port Mirroring, Rapid Spanning Tree and Misc Configuration.
Additionally, the firmware includes advanced features such as IGMP snooping, QoS (Quality of Service), broadcast storm and
bandwidth control, to enhance bandwidth utilization.
Powerful Security
The Managed Switch offers comprehensive Access Control List (ACL) for enforcing security to the edge. Its protection
mechanisms comprises of Port-based 802.1X user and device authentication. Moreover, the switch provides MAC filter and
Static MAC for enforcing security policies to the edge. The administrators can now construct highly secured corporate networks
with considerably less time and effort than before.

Web Management
The Managed Switch offers management features that allow users to manage the 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 switch, you
can access the Managed Switch's Web interface applications directly in your Web browser by entering the IP address of the
Managed Switch.
Figure 3-1: Web Management Diagram
You can then use your Web browser to list and manage the Managed Switch configuration parameters from one central location,
just as if you were directly connected to the Managed Switch's console port. Web Management requires either Microsoft
Internet Explorer 6.0 or later, Safari or Mozilla Firefox 3.0 or later.
Figure 3-2: Web Main Screen of Managed Switch
25
NS2503-24P/2C User Manual
SNMP-Based Network Management
You can use an external SNMP-based application to configure and manage the Managed Switch, such as SNMPc Network
Manager, HP Openview Network Node Management (NNM) or What’sup Gold. This management method requires the SNMP
agent on the switch and the SNMP Network Management Station to use the same community 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 get and set community strings for the Managed Switch are public.
Figure 3-3: SNMP Management Diagram
Administration Console
The administration console is an internal, character-oriented, and command line user interface for performing system
administration such as displaying statistics or changing option settings. Using this method, you can view the administration
console from a terminal, personal computer, Apple Macintosh, or workstation connected to the switch's console (serial) port.
There are two ways to use this management method: via direct access or modem port access. The following sections describe
these methods. For more information about using the console, refer to Chapter 5 Console Management.
Figure 3-4: Console Management Diagram
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) to the Managed Switch console (serial) port.
When using this management method, a straight DB9 RS-232 cable is required to connect the switch to the PC. After
making this connection, configure the terminal-emulation program and use the following parameters:
The default parameters are:
57600 bps
8 data bits
No parity
1 stop bit
26
NS2503-24P/2C User Manual
Figure 3-5: Terminal Parameter Settings
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 connecting to the terminal serial port. A workstation attachment under UNIX can use an
emulator such as TIP.
27
NS2503-24P/2C User Manual
Protocols
The Managed Switch supports the following protocols:
Virtual terminal protocols, such as Telnet
Simple Network Management Protocol (SNMP)
Virtual Terminal Protocols
A virtual terminal protocol is a software program, such as Telnet, that allows you to establish a management session from a
Macintosh, a PC, or a UNIX workstation. Because Telnet runs over TCP/IP, you must have at least one IP address configured
on the Managed Switch before you can establish access to it with a virtual terminal protocol.
Terminal emulation differs from a virtual terminal protocol in that you must connect a terminal directly
to the console (serial) port.
To access the Managed Switch through a Telnet session:
1. Make sure that the Managed Switch is configured with an IP address and the Managed Switch is reachable from a
PC.
2. Start the Telnet program on a PC and connect to the Managed Switch.
The management interface is exactly the same with RS-232 console management.
SNMP Protocol
Simple Network Management Protocol (SNMP) is the standard management protocol for multi-vendor IP networks. SNMP
supports transaction-based queries that allow the protocol to format messages and to transmit information between reporting
devices and data-collection programs. SNMP runs on top of the User Datagram Protocol (UDP), offering a
connectionless-mode service.
Management Architecture
All of the management application modules use the same Messaging Application Programming Interface (MAPI). By unifying
management methods with a single MAPI, configuration parameters set using one method i.e console port, can immediately be
displayed by the other management methods (for example, SNMP agent of Web browser).
The management architecture of the switch adheres to the IEEE open standard. This compliance assures customers that the
Managed Switch is compatible with, and will interoperate with other solutions that adhere to the same open standard.

NS2503-24P/2C User Manual
Web-Based Management
This section introduces the configuration and functions of the Web-Based management.
About Web-based Management
The Managed Switch offers management features that allow users to manage the Managed Switch from anywhere on the
network through a standard browser such as Microsoft Internet Explorer.
The Web-Based Management supports Internet Explorer 6.0. It is based on Java Applets with an aim to reduce network
bandwidth consumption, enhance access speed and present an easy viewing screen.
By default, IE6.0 or later version does not allow Java Applets to open sockets. The user has to
explicitly modify the browser setting to enable Java Applets to use network ports.
The Managed Switch can be configured through an Ethernet connection, make sure the manager PC must be set on same the
IP subnet address with the Managed Switch.
For example, the default IP address of the 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 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 relative configuration on
manager PC.
