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.

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

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. With the built-in web-based management interface, the NS4802-24P-4S-2X offers an easy-to-use, platform

independent management and configuration facility. The NS4802-24P-4S-2X supports SNMP and it can be managed via any

management software based on standard of SNMP v1 and v2 protocol. For reducing product learning time, the

NS4802-24P-4S-2X offers Cisco-like command via Telnet or console port and customer doesn’t need to learn new command

from these switches. Moreover, the NS4802-24P-4S-2X offers remote secure management by supporting SSH, SSL and

SNMPv3 connection which can be encrypted the packet content at each session.

Flexible and Extendable Solution

The 4 mini-GBIC SFP slots built in the NS4802-24P-4S-2X support dual speed as it features 100BASE-FX and

1000BASE-SX/LX SFP (Small Form-factor Pluggable) fiber-optic modules. Now the administrator can flexibly choose the

suitable SFP transceiver according to not only the transmission distance, but also the transmission speed required. The

distance can be extended from 550 meters to 2km (multi-mode fiber) and up to above 10/20/30/40/50/70 kilometers

(single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.

Intelligent SFP Diagnosis Mechanism

The NS4802 supports SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily

monitor real-time parameters of the SFP and SFP+ transceivers, such as optical output power, optical input power, temperature,

laser bias current, and transceiver supply voltage.

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.
