1.2 Product Description
Cost-effective 10Gbps Uplink Capacitated Managed High Power PoE Switch for Large Surveillance Applications
The NS4702 is the latest generation of Interlogix Managed Gigabit PoE Switches featuring Interlogix intelligent PoE functions to
improve the availability of critical business applications. It provides IPv6/IPv4 Layer 3 static routing and built-in L2/L4 Gigabit
Switching engine along with 24 10/100/1000Base-T ports featuring 30-watt 802.3at PoE+, 4 Gigabit SFP fiber slots and 4 10Gbps
SFP+ fiber slots. With total shared power budget up to 440 watts for different kinds of PoE applications, it provides a quick safe and
cost-effective Power over Ethernet network solution to IP security surveillance for small businesses and enterprises.
Flexible and Extendable 10Gbps Ethernet Solution
10G Ethernet is a big leap in the evolution of Ethernet. Each of the SFP+ slot supports Dual-Speed, 10GBase-SR/LR or
1000Base-SX/LX, meaning the administrator now can flexibly choose the suitable SFP/SFP+ transceiver according to the
transmission distance or the transmission speed required to extend the network efficiently. With its 4-port, 10G Ethernet link
capability, the NS4702 provides broad bandwidth and powerful processing capacity.
Centralized Power Management for Gigabit Ethernet PoE Networking
To fulfill the needs of higher power required PoE network applications with Gigabit speed transmission, the NS4702 features
high-performance Gigabit IEEE 802.3af PoE (up to 15.4 watts) and IEEE 802.3at PoE+ (up to 30 watts) on all ports. It perfectly
meets the power requirement of PoE VoIP phone and all kinds of PoE IP cameras such as IR, PTZ, speed dome cameras or even
box type IP cameras with built-in fan and heater for high power consumption.
The NS4702 PoE capabilities also help to reduce deployment costs for network devices as a result of freeing from restrictions of
power outlet locations. Power and data switching are integrated into one unit, delivered over a single cable and managed centrally. It
thus eliminates cost for additional AC wiring and reduces installation time.
Built-in Unique PoE Functions for Surveillance Management
As a managed PoE Switch for surveillance network, the NS4702 features intelligent PoE Management functions:
PD ALIVE Check
Schedule Power Recycle
SMTP/SNMP Trap Event Alert
PoE Schedule
11
Intelligent Powered Device Alive Check
The NS4702 can be configured to monitor connected PD (Powered Device) status in real-time via ping action. Once the PD stops
working and it is without response, the NS4702 will resume 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 management
burden.
Schedule Power Recycle
The NS4702 allows each of the connected PD (Powered Device) to reboot in a specific time each week. Therefore, it will reduce the
chance of PD (Powered Device) crash resulting from buffer overflow.
SMTP/SNMP Trap Event alert
Though most NVR or camera management software offers SMTP email alert function, the NS4702 further provides event alert
function to help to diagnose the abnormal device owing to whether or not there is a break of the network connection, loss of PoE
power or the rebooting response by PD Alive Check process.
12
PoE Schedule for Energy Saving
Besides being used for IP surveillance, theNS4702 is certainly applicable to construct any PoE network including VoIP and wireless
LAN. Under the trend of energy saving worldwide and contributing to the environmental protection on the Earth, the NS4702 can
effectively control the power supply besides its capability of giving high watts power. The “PoE schedule” function helps you to
enable or disable PoE power feeding for each PoE port during specified time intervals and it is a powerful function to help SMB or
Enterprise save power and money.
Solution for IPv6 Networking
Faced with the increasingly large number of IP cameras and Wireless APs installed and deployed in all kinds of applications, more
and more network facilities start to support the IPv6 protocol for the next-generation networking. By supporting both the IPv4 and
IPv6 and plenty of management functions with easy and friendly management interfaces, the NS4702 is the best choice for IP
surveillance and wireless service providers to connect with the IPv6 network.
IPv6 / IPv4 Dual St ack
By supporting IPv6 management features and also backward compatible with IPv4, the NS4702 helps the SMB to step in the IPv6
era with the lowest investment but not need to replace the network facilities while the ISP constructs the IPv6 FTTx edge network.
13
IPv4 and IPv6 VLAN Routing for Secure and Flexible Management
To help customers stay on top of their businesses, the NS4702 switch not only provides ultra high transmission performance and
excellent layer 2 technologies, but also offers IPv4/IPv6 VLAN routing feature which allows to cross over different VLANs and
different IP addresses for the purpose of having a highly secured, flexible management and simpler networking application.
Enhanced Security
The NS4702 offers a comprehensive Layer 2 to Layer 4 Access Control List (ACL) for enforcing security to the edge. It can be
used to restrict network access by denying packets based on source and destination IP address, TCP/UDP ports or defined typical
network applications. Its protection mechanism also comprises 802.1X Port-based and MAC-based user and device authentication.
With the private VLAN function, communication between edge ports can be prevented to ensure user privacy. Furthermore, the
NS4702 provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent IP snooping from attack
and discard ARP packets with invalid MAC address. The network administrators can now construct highly secured corporate
networks with considerably less time and effort than before.
Robust Layer 2 Features
The NS4702 can be programmed for advanced switch management functions such as dynamic port link aggregation, Q-in-Q VLAN,
private VLAN, Multiple Spanning Tree Protocol (MSTP), Layer 2/4 QoS, bandwidth control and IGMP/MLD Snooping. The
NS4702 also provides 802.1Q Tagged VLAN, and the VLAN groups allowed will be maximally up to 256. Via aggregation of
supporting ports, the NS4702 allows the operation of a high-speed trunk combining multiple ports. It enables up to 14 groups of 8
ports for trunk maximum and supports connection fail-over as well.
Excellent Traffic Control
The NS4702 is loaded with powerful traffic management and QoS features to enhance connection services by SMBs. The QoS
features include wire-speed Layer 4 traffic classifiers and bandwidth limiting that are particular useful for multi-tenant unit, multi
business unit, Telco, or Network Service Provide applications. It also empowers the enterprises to take full advantages of the limited
network resources and guarantees the best performance in VoIP and Video conferencing transmission.
Efficient and Secure Management
The NS4702 Managed Switch is equipped with console, WEB and SNMP management interfaces. With the built-in Web-based
management interface, the NS4702 offers an easy-to-use, platform-independent management and configuration facility. The
NS4702 supports standard Simple Network Management Protocol (SNMP) and can be managed via any management software that
supports SNMP protocol. For text-based management, the NS4702 can be accessed via Telnet and the console port. Moreover, the
NS4702 offers secure remote management by supporting SSH, SSL and SNMPv3 connection which encrypt the packet content at
each session.
Flexibility and Extension Solution
The NS4702 provides 4 extra Gigabit TP/SFP combo interfaces supporting 10/100/1000Base-T RJ-45 copper to connect with
surveillance network devices such as NVR, Video Streaming Server or NAS to facilitate surveillance management. Or through these
dual-speed fiber SFP slots, it can also connect with the 100Base-FX / 1000Base-SX/LX SFP (Small Form-factor Pluggable) fiber
transceiver to backbone switch and monitoring center in long distance. The distance can be extended from 550 meters to 2
kilometers (multi-mode fiber) and up to above 10/20/30/40/50/70/120 kilometers (single-mode fiber or WDM fiber). They are well
suited for applications within the enterprise data centers and distributions.

1. It is recommended to use Interlogix SFP on the Managed Switch. If you insert an SFP transceiver
that is not supported, the Managed Switch will not recognize it.
2. Port 21 to Port 24 are a shared SFP slot that supports the Gigabit and Fast Ethernet SFP
transceiver.
3. Port 25 to Port 28 are a shared SFP+ slot that supports the 10 Gigabit SFP+ transceiver and
Gigabit SFP transceiver.
1. Before we connect the NS4702-24P-4S-4X to the other network device, we have to make sure both sides of the SFP
transceivers are with the same media type, for example: 1000Base-SX to 1000Base-SX, 1000Bas-LX to 1000Base-LX.
2. Check whether the fiber-optic cable type matches with the SFP transceiver requirement.
To connect to 1000Base-SX SFP transceiver, please use the multi-mode fiber cable with one side being the male duplex
LC connector type.
To connect to 1000Base-LX SFP transceiver, please use the single-mode fiber cable with one side being the male duplex
LC connector type.
Connect the Fiber Cable
1. Insert the duplex LC connector into the SFP/SFP+ transceiver.
2. Connect the other end of the cable to a device with SFP/SFP+ transceiver installed.
3. Check the LNK/ACT LED of the SFP/SFP+ slot on the front of the Managed Switch. Ensure that the SFP/SFP+ transceiver is
operating correctly.
4. Check the Link mode of the SFP/SFP+ port if the link fails. To function with some fiber-NICs or Media Converters, user has to
set the port Link mode to “10GForce”, “1000 Force” or “100 Force”.
32
Remove the Transceiver Module
1. Make sure there is no network activity anymore.
2. Remove the Fiber-Optic Cable gently.
3. Lift up the lever of the MGB module and turn it to a horizontal position.
4. Pull out the module gently through the lever.

3. SWITCH MANAGEMENT
This chapter explains the methods that you can use to configure management access to the Managed Switch. It describes the types
of management applications and the communication and management protocols that deliver data between your management
device (workstation or personal computer) and the system. It also contains information about port connection options.
This chapter covers the following topics:
Requirements
Management Access Overview
Administration Console Access
Web Management Access
SNMP Access
Standards, Protocols, and Related Reading
3.1 Requirements
Workstations running Windows 2000/XP, 2003, Vista/7/8, 2008, MAC OS9 or later, or Linux, UNIX , or other platforms
compatible with TCP/IP protocols.
Workstation is installed with Ethernet NIC (Network Interface Card)
Serial Port connect (Terminal)
The above PC with COM Port (DB9 / RS-232) or USB-to-RS-232 converter
Ethernet Port connect
Network cables - Use standard network (UTP) cables with RJ45 connectors.
The above workstation is installed with WEB Browser and JAVA runtime environment Plug-in
It is recommended to use Internet Explore 7.0 or above to access Managed Switch.
34
3.2 Management Access Overview
The Managed Switch gives you the flexibility to access and manage it using any or all of the following methods:
An administration console
Web browser interface
An external SNMP-based network management application
The administration console and Web browser interface support are embedded in the Managed Switch software and are available for
immediate use. Each of these management methods has their own advantages. Table 3-1 compares the three management
methods.
Method Advantages Disadvantages
Console
Web Browser
SNMP Agent
No IP address or subnet needed
Text-based
Telnet functionality and HyperTerminal
built into Windows
95/98/NT/2000/ME/XP operating
systems or higher.
Secure
Ideal for configuring the switch remotely
Compatible with all popular browsers
Can be accessed from any location
Most visually appealing
Communicates with switch functions at
the MIB level
Based on open standards
Must be near the switch or use dial-up
connection
Not convenient for remote users
Modem connection may prove to be unreliable
or slow
Security can be compromised (hackers need
only know the IP address and subnet mask)
May encounter lag times on poor connections
Requires SNMP manager software
Least visually appealing of all three methods
Some settings require calculations
Security can be compromised (hackers need
only know the community name)
Table 3-1 Comparison of Management Methods
35
3.3 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 Managed Switch's console (serial) port.
Figure 3-1-1: Console Management
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 to use the following parameters:
The default parameters are:
115200 bps
8 data bits
No parity
1 stop bit
Figure 3-1-2: Terminal Parameter Settings
You can change these settings, if desired, after you log on. This management method is often preferred because you can remain
36
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.
3.4 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 3-1-3: Web Management
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 7.0 or later, Safari or Mozilla Firefox 1.5 or later.
Figure 3-1-4: Web Main Screen of Managed Switch
37
3.5 SNMP-based Network Management
You can use an external SNMP-based application to configure and manage the 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
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 Net-work 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 getting and setting community strings for the Managed Switch is public.
Figure 3-1-5: SNMP Management
38
4. WEB CONFIGURATION
This section introduces the configuration and functions of the Web-based management from Managed Switch.
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 7.0. 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, IE7.0 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, making sure the manager PC must be set on the same 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.
Figure 4-1-1: Web Management
Logging on the Managed Switch
1. Use Internet Explorer 7.0 or above Web browser. Enter the factory-default IP address to access the Web interface. The
factory-default IP Address is shown as follows:

Advertising Duration
Indicates the UPnP operation mode. Possible modes are:
Enabled: Enable UPnP mode operation.
Disabled: Disable UPnP mode operation.
When the mode is enabled, two ACEs are added automatically to trap UPnP
related packets to CPU. The ACEs are automatically removed when the mode is
disabled.
The TTL value is used by UPnP to send SSDP advertisement messages.
Valid values are in the range of 1 to 255.
The duration, carried in SSDP packets, is used to inform a control point or control
points how often it or they should receive a SSDP advertisement message from
this switch. If a control point does not receive any message within the duration, it
will think that the switch no longer exists. Due to the unreliable nature of UDP, in
the standard it is recommended that such refreshing of advertisements to be
done at less than one-half of the advertising duration. In the implementation, the
switch sends SSDP messages periodically at the interval one-half of the
advertising duration minus 30 seconds. Valid values are in the range 100 to
86400.

4.2.9 DHCP Relay
Configure DHCP Relay on this Page. DHCP Relay is used to forward and to transfer DHCP messages between the clients and the
server when they are not on the same subnet domain.
The DHCP option 82 enables a DHCP relay agent to insert specific information into a DHCP request packets when forwarding client
DHCP packets to a DHCP server and remove the specific information from a DHCP reply packets when forwarding server DHCP
packets to a DHCP client. The DHCP server can use this information to implement IP address or other assignment policies.
Specifically the option works by setting two sub-options:
Circuit ID (option 1)
Remote ID (option2).
The Circuit ID sub-option is supposed to include information specific to which circuit the request came in on.
The Remote ID sub-option was designed to carry information relating to the remote host end of the circuit.
The definition of Circuit ID in the switch is 4 bytes in length and the format is "vlan_id" "module_id" "port_no". The parameter of
"vlan_id" is the first two bytes representing the VLAN ID. The parameter of "module_id" is the third byte for the module ID (in
standalone switch it always equals 0; in stackable switch it means switch ID). The parameter of "port_no" is the fourth byte and it
means the port number.
The Remote ID is 6 bytes in length, and the value equals the DHCP relay agent’s MAC address. The DHCP Relay Configuration
screen in Figure 4-2-12 appears.

The switch stores its configuration in a number of text files in CLI format. The files are either virtual (RAM-based) or stored in flash
on the switch.
There are three system files:
running-config: A virtual file that represents the currently active configuration on the switch. This file is volatile.
startup-config: The startup configuration for the switch, read at boot time.
default-config: A read-only file with vendor-specific configuration. This file is read when the system is restored to default
settings.
It is also possible to store up to two other files and apply them to running-config, thereby switching configuration.

4.3 Simple Network Management Protocol
4.3.1 SNMP Overview
The Simple Network Management Protocol (SNMP) is an application layer protocol that facilitates the exchange of management
information between network devices. It is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite. SNMP
enables network administrators to manage network performance, find and solve network problems, and plan for network growth.
An SNMP-managed network consists of three key components: Network management stations (NMSs), SNMP agents,
Management information base (MIB) and network-management protocol：
■ Network management stations (NMSs)：Sometimes called consoles, these devices execute management applications that
monitor and control network elements. Physically, NMSs are usually engineering workstation-caliber computers with fast
CPUs, megapixel color displays, substantial memory, and abundant disk space. At least one NMS must be present in each
managed environment.
■ Agents：Agents are software modules that reside in network elements. They collect and store management information such
as the number of error packets received by a network element.
■ Management information base (MIB)：A MIB is a collection of managed objects residing in a virtual information store.
Collections of related managed objects are defined in specific MIB modules.
■ Network-management protocol：A management protocol is used to convey management information between agents and
NMSs. SNMP is the Internet community's de facto standard management protocol.
SNMP Operations
SNMP itself is a simple request/response protocol. NMSs can send multiple requests without receiving a response.
■ Get -- Allows the NMS to retrieve an object instance from the agent.
■ Set -- Allows the NMS to set values for object instances within an agent.
■ Tr ap - - Used by the agent to asynchronously inform the NMS of some event. The SNMPv2 trap message is designed to
replace the SNMPv1 trap message.
77
SNMP community
An SNMP community is the group that devices and management stations running SNMP belong to. It helps define where information
is sent. The community name is used to identify the group. A SNMP device or agent may belong to more than one SNMP community.
It will not respond to requests from management stations that do not belong to one of its communities. SNMP default communities
are:
。 Write = private
。 Read = public
Use the SNMP Menu to display or configure the Managed Switch's SNMP function. This section has the following items:

When set each port to run at 100M Full, 100M Half, 10M Full, and 10M Half-speed modes. The
Auto-MDIX function will disable.
When a fixed-speed setting is selected, that is what is used. The Current Rx
column indicates whether pause frames on the port are obeyed, and the Current
Tx column indicates whether pause frames on the port are transmitted. The Rx
and Tx settings are determined by the result of the last Auto-Negotiation.
Check the configured column to use flow control. This setting is related to the
setting for Configured Link Speed.
Enter the maximum frame size allowed for the switch port, including FCS. The
allowed range is 1518 bytes to 10056 bytes.

4.4.4 SFP Module Information
The WGSW-48040HP has supported the SFP module with digital diagnostics monitoring (DDM) function, this feature is also
known as digital optical monitoring (DOM). You can check the physical or operational status of an SFP module via the SFP Module
Information Page. This Page shows the operational status, such as the transceiver type, speed, wavelength, optical output power,
optical input power, temperature, laser bias current and transceiver supply voltage in real time. You can also use the hyperlink of
port no. to check the statistics on a speficic interface. The SFP Module Information screen in Figure 4-4-4 appears.

4.4.5 Port Mirror
Configure port Mirroring on this Page. This function provide to monitoring network traffic that forwards a copy of each incoming or
outgoing packet from one port of a network Switch to another port where the packet can be studied. It enables the manager to keep
close track of switch performance and alter it if necessary.
To debug network problems, selected traffic can be copied, or mirrored, to a mirror port where a frame analyzer can be
attached to analyze the frame flow.
The Managed Switch can unobtrusively mirror traffic from any port to a monitor port. You can then attach a protocol analyzer or
RMON probe to this port to perform traffic analysis and verify connection integrity.
Figure 4-4-7: Port Mirror Application
The traffic to be copied to the mirror port is selected as follows:
All frames received on a given port (also known as ingress or source mirroring).
All frames transmitted on a given port (also known as egress or destination mirroring).
