JetNet 4706 - Industrial Networking Solutions – Industrial Ethernet Switches and Routers

JetNet 4706



JetNet 4706, the full managed industrial PoE switch, is the advanced version from the winner of Best Choice of Computex Taipei 2007 Award, the JetNet 3705/3705f. JetNet 4706 is designed for industrial PoE applications such as IP surveillance or wireless access points, where power source is not conveniently located. It supports intelligent PoE control and schedule management; each of the four PoE ports can be configured in a weekly schedule by hourly basis and PoE on/off can be remotely controlled via SNMP and Web. Compliant to IEEE 802.3af PoE standard, JetNet 4706 can deliver up to 25W power per port and 80W per unit (@60°C) by the forced powering mode.

The two uplink ports of JetNet 4706 series can be configured as Rapid Super Ring ports recovering network failure in less than 5ms, or RSTP ports integrating with other standard switches. Full network management features such as LLDP, JetView Pro i2NMS, SNMP v3, QoS, IGMP snooping v3, are all supported. If the powered device fails to respond after a pre-configured time interval, JetNet 4706 will reboot the powered device and continue to monitor the powered device in every pre-configured time interval. Simply put, the unmanaged powered devices can be managed through JetNet 4706. The award-winning IP31 rigid aluminum flat casing and wide operation temperature range ensure a reliable operation in mass transit vehicles, for outdoor usage, etc.

Easy PoE Configuration
The four PoE ports can be configured to enable, disable, or schedule PoE function by the web interface. The Power mode provides Standard mode for IEEE 802.3af PD, Manual mode for user configuration of the power limit to IEEE 802.3af standard PD, or Ultra mode for user configuration to perform at the 25W power limitation. After configuration, the real-time status of PoE is shown in web interface.

Forced Powering Mode
Korenix provides advanced forced powering control to deliver power to those non-standard PoE devices that cannot be detected as valid PDs. In the early days PoE products that were circulating the market prior to the ratification of PoE standard 802.3af did not comply with the current standard and did not support PD detection and classification. The PoE switch cannot recognized the PD, thus, it will not forward the power. The forced powering ability solves this problem and enables all your PDs.

PoE Port Scheduling
Korenix provides an hourly/weekly scheduling mechanism for advanced power control. Each PoE port can be configured as on/off by hourly basis. This feature meets economical power management, security, or customer-specific requirements.
