1.2 Product Description

High-Density, Resilient Deployment Switch Solution for Gigabit Networking of Enterprise, Campus and Data Center

For the growing Gigabit network and IoT (Internet of Things) demand, IFS has launched a new-generation Stackable Gigabit PoE+ Switch solution, the NS4802-24P-4S-2X, to meet the needs of IP surveillance, enterprises, telecoms and campuses for a large-scale network deployment. The NS4802-24P-4S-2X is Layer 2+ Managed Stackable Gigabit PoE+ Switch, which supports both IPv4 and IPv6 protocols and hardware Layer 3 static routing capability, and provides 24 10/100/1000Mbps Gigabit Ethernet ports, 4 shared Gigabit SFP slots, 2 10G SFP+ uplink slots and another 2 dedicated 10G SFP+ stacked interfaces for stacking the switch. Up to 16 units, 384 Gigabit Ethernet ports and 32 10Gbps SFP+ slots can be managed by a stacking group and you can add ports and functionality as needed.

Efficient Single IP Management

The NS4802-24P-4S-2X applies the advantage of the stacking technology to managing the stack group with one single IP address, which helps network managers to easily manage a stack of switches instead of connecting and setting each unit one by one. The stacking technology also enables the chassis-based switches to be integrated into the NS4802-24P-4S-2X Managed Switch at an inexpensive cost.

11

Highly-reliable Stacking Ability

Through its up to 40Gbps, bi-directional high bandwidth tunnel and stacking technology, the NS4802 gives the enterprises, service providers and telecoms flexible control over port density, uplinks and switch stack performance. The stack redundancy of the NS4802 ensures that data integrity is retained even if one switch in the stack fails. You can even hot-swap switches without disrupting the network, which greatly simplifies the tasks of upgrading the LAN for catering to increasing bandwidth demands.

Cost-effective 10Gbps Uplink Capacity

10G Ethernet is a big leap in the evolution of Ethernet. The two 10G SFP+ slot of the NS4802 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. They greatly support SMB network to achieve 10Gbps high performance in a cost-effective way because 10GbE interface usually could be available in Layer 3 Switch but Layer 3 Switch could be too expensive to SMBs. (Small Businesses)

Solution for IPv6 Networking

By supporting IPv6 / IPv4 dual stack and plenty of management functions with easy and friendly management interfaces, the NS4802 is the best choice for IP surveillance, VoIP and wireless service providers to connect with the IPv6 network. It also helps the SMB to step in the IPv6 era with the lowest investment but not necessary to replace the network facilities while the ISP constructs the IPv6 FTTx edge network.

IPv4 and IPv6 VLAN Routing for Secure and Flexible Management

To help customers stay on top of their businesses, the NS4802 not only provides ultra high transmission performance and excellent layer 2 technologies, but also offers IPv4/IPv6 VLAN routing feature which allows crossing over different VLANs and different IP addresses for the purpose of having a highly secured, flexible management and simpler networking application.

Robust Layer2 Features

12

The NS4802 can be programmed for advanced switch management function, such as dynamic port link aggregation, Q-in-Q VLAN, Multiple spanning tree protocol (MSTP), Layer 2/4 QoS, bandwidth control and IGMP/MLD snooping. The NS4802 allows the operation of a high-speed trunk combining multiple ports. It enables up to 3 groups of 6 ports for trunk maximum and supports connection fail-over as well.

Powerful Security

The NS4802-24P-4S-2X offers comprehensive layer2 to layer4 access control list (ACL) for enforcing security to the edge. It can be used to restrict to network access by denying packets based on source and destination IP address, TCP/UDP port number 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.

Enhanced Security and Traffic Control

The NS4802-24P-4S-2X also 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 administrator can now construct highly secured corporate networks with considerably less time and effort than before.

User-friendly Secure Management

For efficient management, the NS4802-24P-4S-2X managed switch is equipped with console, web and SNMP management interfaces.

Centralized Power Management for Gigabit Ethernet PoE Networking

To fulfill the needs of higher power required PoE network applications with Gigabit speed transmission, the NS4802 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 NS4802’s 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 NS4802 features intelligent PoE Management functions:

Scheduled Power Recycling

SMTP/SNMP Trap Event Alert

PoE Schedule

Scheduled Power Recycling

The NS4802 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 offer SMTP email alert function, the NS4802 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.

PoE Schedule for Energy Saving

Besides being used for IP surveillance, theNS4802 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 NS4802 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 SMBs or enterprises save power and money.

Step 6: Proceed with Steps 4 and 5 of session 2.2.1 Desktop Installation to connect the network cabling and supply power to the Managed Switch.

2.2.3 Installing the SFP/SFP+ Transceiver

The sections describe how to insert an SFP/SFP+ transceiver into an SFP/SFP+ slot. The SFP/SFP+ transceivers are hot-pluggable and hot-swappable. You can plug in and out the transceiver to/from any SFP/SFP+ port without having to power down the Managed Switch, as the Figure 2-2-4 shows..

26

Figure 2-2-4: Plug-in the SFP/SFP+ Transceiver

Approved IFS SFP/SFP+ Transceivers

IFS Managed Switch supports both single mode and multi-mode SFP/SFP+ transceiver. The following list of approved IFS SFP/SFP+ transceivers is correct at the time of publication:

Fast Ethernet Transceiver (100Base-X SFP)

Gigabit Ethernet Transceiver (1000BASX-LX-BX, Fiber Bi-Directional SFP)

27

10Gigabit Ethernet Transceiver (10GBASE-X SFP+)

■10 Gigabit Stacked SFP+ slot

10GBASE-SR/LR mini-GBIC slot, SFP+ Transceiver Module supports from 300 meters (multi-mode fiber) to up to 10 kilometers (single-mode fiber)

	Model	Speed (Mbps)	Connector	Fiber Mode	Distance	Wavelength (nm)	Operating Temp.
			Interface
	S40-2MLC	10G	LC	Multi Mode	300m	850nm	0 ~ 60
	S40-2SLC-10	10G	LC	Single Mode	10km	1310nm	0 ~ 60

1.It is recommended to use IFS 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 26 are a shared SFP+ slot that supports the 10 Gigabit SFP+ transceiver and Gigabit SFP transceiver.

1.Before we connect the NS4802 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. Tofunction with some fiber-NICs or Media Converters, user has to set the port Link mode to “10GForce”, “1000 Force” or “100 Force”.

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 SFP module and turn it to a horizontal position.

4.Pull out the module gently through the lever.

28

Figure 2-2-5: How to Pull Out the SFP/SFP+ Transceiver

Never pull out the module without lifting up the lever of the module and turning it to a horizontal position. Directly pulling out the module could damage the module and the SFP/SFP+ module slot of the Managed Switch.

2.3 Stack Installation

NS4802-24P-4S-2X

The NS4802 Managed Switch series provides a switch stacking function to manage up to 16 switches using a single IP address. And up to 320 Gigabit Ethernet ports, 64 Gigabit TP/SFP ports and 32 high-capacity 10G SFP+ ports can be managed by a stacking group and you can add ports and functionality as needed. You can add the NS4802 switch as needed to support more network clients, knowing that your switching fabric will scale to meet increasing traffic demands.

Two types of stack topologies are supported by the NS4802.

Chain topology (same as a disconnected ring)

Ring topology

1.Please note that from now on the stacking example images are coming from NS4802, however, as NS4802-24P stacking ports are on the front panel, but the stacking cable connection rule is totally same with NS3601.

2.if you remove one of switch from stacking group and causes stacking ID without sequence, please re-assign stacking ID from “Stack Configuration“before you make the other operation.

3.Stack ports are port27 and port28 and the stacking ports could be used for stacking only, it can’t be set to “uplink”.

Please find the following picture for sample connection.
