User’s Manual of IGS-604HPT-M12
1.2 Product Description
Suitable for Industrial Environment
PLANET IGS-604HPT-M12, an Industrial Managed Ethernet Switch, comes with an IP67-rated industrial case, 4-port
10/100/1000T 802.3at PoE, 2-port 10/100/1000T, and static Layer 3 routing, providing 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. The IGS-604HPT-M12 can be easily mounted on a DIN rail or wall taking up less space. Each of the four Gigabit
PoE+ ports provides 36 watts of power, which means a total power budget of up to 144 watts can be utilized simultaneously
without considering the different types of PoE applications being employed. It also provides a quick, safe and cost-effective
Power over Ethernet network solution to IP security surveillance for small businesses and enterprises.
Waterproof and Dustproof M12 Ethernet Connector
The IGS-604HPT-M12 is equipped with a 6-port 10/100/1000BASE-T auto-negotiation waterproof and dustproof M12 connector
with 4-port IEEE 802.3at PoE+ (Port 3 to Port 6); each PoE port provides 36-watt PoE output. The M12 connector provides tight
and strong connection and guarantees stable Ethernet operation performance under high vibration and shock environment and
ensures it comes with the industrial protection rating of IP67 capable of withstanding humidity, dirt, dust, shock, vibrations, heat
and cold.
11
User’s Manual of IGS-604HPT-M12
Environmentally Hardened Design
The IGS-604HPT-M12 is able to protect itself from dust and water ingress, and to operate under the temperature range from -40
to 75 degrees C. All these features ensure the highest level of reliability for mission-critical applications in any difficult
environment.
Dual Power Input for High Availability Network System
The IGS-604HPT-M12 features a strong dual power input system (Dual 48V~56V DC) incorporated into customer’s automation
network to enhance system reliability and uptime. For example, when DC Power 1 fails to work, the hardware failover function
will be activated automatically to keep powering the IGS-604HPT-M12 via DC Power 2 alternatively without any loss of
operation.
Centralized Power Management for Gigabit Ethernet PoE Networking
To fulfill the needs of higher power required PoE network applications with Gigabit speed transmission, the IGS-604HPT-M12
features high-performance Gigabit IEEE 802.3at PoE+ (up to 36 watts) on all ports. It perfectly meets the power requirements of
PoE VoIP phone, PoE Wireless AP and all kinds of PoE IP cameras such as IR, PTZ, speed dome cameras and even box type
IP cameras with a built-in fan and heater for high power consumption. The IGS-604HPT-M12’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.

User’s Manual of IGS-604HPT-M12
Built-in Unique PoE Functions for Surveillance Management
As a managed PoE Switch for surveillance network, the IGS-604HPT-M12 features the following intelligent PoE management
The IGS-604HPT-M12 can be configured to monitor a connected PD (Powered Device) status in real time via ping action. Once
the PD stops working and it is without response, the IGS-604HPT-M12 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, thus reducing
administrator management burden.
Scheduled Power Recycling
The IGS-604HPT-M12 allows each of the connected PDs to reboot at a specified time each week. Therefore, it will reduce the
chance of PD crash resulting from buffer overflow.
13
User’s Manual of IGS-604HPT-M12
SMTP/SNMP Trap Event Alert
Though most NVR or camera management software offers SMTP email alert function, the IGS-604HPT-M12 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 the PD Alive Check process.
PoE Schedule for Energy Saving
Besides being used for IP surveillance, the IGS-604HPT-M12 is certainly applicable to build 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 IGS-604HPT-M12 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 and enterprises save energy and budget.

User’s Manual of IGS-604HPT-M12
Redundant Ring, Fast Recovery for Critical Network Applications
The IGS-604HPT-M12 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 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 20ms.
IPv6/IPv4 Dual Stack
Supporting both IPv6 and IPv4 protocols, the IGS-604HPT-M12 helps data centers, campuses, telecoms, and moreto
experience the IPv6 era with the lowest investment as its network facilities need not be replaced or overhauled if the IPv6 FTTx
edge network is set up.

User’s Manual of IGS-604HPT-M12
Laye
r 3 IPv4 and IPv6 VLAN Routing for Secure and Flexible Management
The IGS-604HPT-M12 not only provides ultra high transmission performance, and excellent layer 2 and layer 4 technologies,
but also layer 3 IPv4/IPv6 VLAN routing feature which allows to crossover different VLANs and different IP addresses for the
purpose of having a highly-secure, flexibly-managed and simple networking application.
Robust Layer 2 Features
The IGS-604HPT-M12 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 to Layer 4 QoS, bandwidth control and
IGMP/MLD Snooping. Via the link aggregation of supporting ports, the IGS-604HPT-M12 allows the operation of a high-speed
trunk to combine with multiple fiber ports and supports fail-over as well.
Powerful Security
The IGS-604HPT-M12 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 80 2.1X 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. The IGS-604HPT-M12 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 administrators can now
construct highly-secure corporate networks with considerably less time and effort than before.
Excellent Traffic Control
The IGS-604HPT-M12 is loaded with powerful traffic management and QoS features to enhance connection services by
telecoms and ISPs. The QoS feature includes wire-speed Layer 4 traffic classifiers and bandwidth limit that are particularly
useful for multi-tenant units, multi-business units, Telco and network service providers’ applications. It also empowers the
industrial environment to take full advantage of the limited network resources and guarantees the best performance in VoIP and
video conferencing transmission.
Efficient and Secure Management
With built-in Web-based management interface, the IGS-604HPT-M12 L2+ Managed Switch offers an easy-to-use,
platform-independent management and configuration facility which includes Web and SNMP management interfaces. The
SNMP can be managed via any management software based on the standard of SNMP Protocol. For reducing product learning
time, it offers Cisco-like command via Telnet and customer does not need to learn new console command. Moreover, it also
offers secure remote management by supporting SSH, SSL and SNMP v3 connections which encrypt the packet content at
each session.
