control and security features to ensure the reliable 

and secure network connection. To optimize the 

industrial network environment, the switch supports 

Tag -based VLAN, IGMP Snooping, IEEE 802.1s 

Multiple Spanning Tree, IEEE 802.1w Rapid Spanning 

Tree, Quality of Service (QoS), Link Aggregation 

Control Protocol (LACP), Rate Control, Port mirror,

To avoid hacker’s attacks and ensure the secure data 

transmission, JetNet 4508 V2 series features DHCP 

client, DHCP server with IP and MAC binding, 802.1X

For easy of configuration and monitoring, the JetNet 

4508 V2 offers various of management interface , such 

as SNMP, Web Browser, In-Band Telnet and Out-Band 

Local serial console with command like interface. 

The switch status as well as all the networking features 

can be enabled through these management interfaces. 

The failure notifications are later sent through e-mail, 

SNMP trap, Local/Remote system log, Fault event alarm 

relay. 

The JetNet 4508 V2 designed with 32 bits ARM-

9E running at 180 MHz and with up to 200MIPS  

performance, combines an embedded hardware 

based watchdog timer to avoid system crashed by 

environmental factors, such as intense electromagnetic 

interference, extreme temperature variations and/ or any 

wrong instruction looping. This outstanding design can 

ensure the system stability and reliability when it installed 

in hardened environment.

The Modbus TCP/IP protocol is supported in JetNet 

4508 V2 series for factory automation applications. It 

enables administrator to connect to data acquisition 

(SCADA) system and read the switch's operating 

information using its own Modbus TCP/IP master 

program for monitoring and maintaining switch’s status. 

With the supported Modbus TCP/IP, the JetNet 4508 V2 

series become an element of factory automation such 

as the Programmable Logic Controller (PLC), Distributed 

Control System (DCS), and allow users to monitor/

maintain factory equipment on the HMI (Human Machine 

Interface) system, including production information 

and communication status.  Therefore, user does not 

need to integrate multiple management platforms to 

monitor factory equipment: with just a single JetNet 

4508 V2 platform users can easily achieve enhanced 

monitoring and maintenance of the entire factory.
