Chapter 1: Introduction

NS3552-16P-2T-2S User Manual 5

Product description

The industrial managed switch is specially designed to build a full Gigabit backbone to

transmit reliable and high-speed data in demanding heavy industrial environments and

forward data to remote network through fiber optic cabling. It comes with an IP30

rugged case and redundant power system. Besides support for 60 Gbps switch fabric

to handle extremely large amounts of video, voice, and important data in a secure

topology, the industrial managed switch provides user-friendly, 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 applications

The industrial managed switch supports redundant ring technology and features strong,

rapid self-recovery capability to prevent 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 the customer’s industrial automation network to enhance system reliability

and uptime in harsh factory environments. In a certain simple ring network, the

recovery time of data link can be as fast as 20 ms.

Environmentally hardened design

With its IP30 aluminum case, 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 a 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°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 supports digital input and digital output on its upper

panel. The external alarm allows users to use the digital input to detect an external

device’s status (such as door intrusion detector), and send an event alarm to the

administrators. The digital output can be used to alarm the administrators if the

industrial managed switch port is link-down, link-up, or power-dead.

Chapter 1: Introduction

6 NS3552-16P-2T-2S User Manual

Intelligent powered device alive check

The industrial managed switch can be configured to monitor connected PD status in

real time via a ping action. After the PD stops working and responding, the industrial

managed switch resumes the PoE port power and puts the PD back to work. The

industrial managed switch greatly enhances the network reliability through the PoE port

resetting the PD’s power source and reducing the administrator management burden.

PoE schedule for energy saving

Under the trend of energy saving worldwide and contributing to environmental

protection, the industrial managed switch can effectively control the power supply in

Chapter 1: Introduction

NS3552-16P-2T-2S User Manual 7

addition to its capability of provideing high Watt power. The “PoE schedule” function

helps you to enable or disable PoE power feeding for each PoE port during specified

time intervals, and is a powerful function to help SMBs or enterprises save power and

money.

Robust layer 2 feature

The industrial managed switch can be programmed for advanced switch management

functions such as dynamic port link aggregation, Q-in-Q VLAN, Multiple Spanning Tree

Protocol (MSTP), layer 2 to layer 4 QoS, bandwidth control, and IGMP / MLD snooping.

The industrial managed switch allows the operation of a high-speed trunk combining

multiple ports.

IPv6/IPv4 full-function secure switch for building automation networking

The industrial managed switch is the ideal solution to fulfilling the demand of IPv6

management gigabit Ethernet switches, especially in the industrial-hardened

environment. It supports both IPv4 and IPv6 protocols, advanced Layer 2 to Layer 4

data switching and redundancy, QoS traffic control, network access control and

authentication, and secure management features to protect customer’s industrial and

building automation network connectivity with reliable switching recovery capability that

is suitable for implementing fault tolerant and mesh network architectures.

IPv4/IPv6 VLAN routing for secure and flexible management

The industrial managed switch offers a IPv4/IPv6 VLAN routing feature that allows

cross over of different VLANs and different IP addresses for the purpose of having a

highly secured, flexible management and simpler networking application.

User-friendly management interfaces

For efficient management, the industrial managed switch is equipped with console,

web, and SNMP management interfaces. With the built-in web-based management

interface, the industrial managed switch offers an easy-to-use, platform-independent

management and configuration facility. The industrial managed switch supports

standard Simple Network Management Protocol (SNMP) and can be managed by any

management software based on the standard SNMP v1 or v2 protocol. For reducing

Chapter 1: Introduction

8 NS3552-16P-2T-2S User Manual

product learning time, the industrial managed switch offers Cisco-like command via

Telnet or console port, and the customer doesn’t need to learn new commands from

these switches. Moreover, the industrial managed switch offers secure management

remotely by supporting SSH, SSL, and SNMP v3 connections where the packet content

can be encrypted at each session.

Intelligent SFP diagnostic mechanism

The industrial managed switch series supports a SFP-DDM (Digital Diagnostic Monitor)

function that can 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.

Flexible and extendable solution

The industrial managed switch features 100BASE-FX and 1000BASE-SX/LX SFP

(Small Form-factor Pluggable) fiber-optic modules, meaning the administrator now can

flexibly choose the suitable SFP transceiver according to the transmission distance or

the transmission speed required to extend the network efficiently.

1588 precision time protocol for industrial computing networks

The industrial managed switch is intended for telecom and carrier Ethernet

applications, supporting MEF service delivery and timing over packet solutions for the

IEEE 1588 Precision Time Protocol and synchronous Ethernet.
