JetNet 4706, an improved and strengthen manageable industrial PoE switch, is the successor of Best Choice of Computex Taipei 2007 Award winner, 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 remote controlled via SNMP and Web. JetNet 4706 is compliant to both IEEE 802.3af PoE as well as the pioneer standard of IEEE802.3at PoE Plus design (enhancement of 802.3af) for boosting PoE delivery up to 30W in each of the four PoE ports. JetNet 4706 can auto-detect 24V & 48V power input and deliver 24V & 48V PoE output allows more applications where 48VDC is not an option.
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 SNMP v3, QoS, IGMP v3, LACP port trunk 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. Also, unmanageable powered devices can be managed through JetNet 4706 software. The award-winning IP-31 rigid aluminum flat casing and wide operation temperature range ensure a reliable operation in places such mass transit vehicles or outdoor usage.

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 30w power limitation. After configuration, the real-time status of PoE is shown in web interface.

Scheduling PoE Control
The concept from UPS power scheduling control is used for JetNet 4706 PoE power delivery. JetNet 4706 can follow the weekly schedule on an hourly basis to power on/off on any given PoE port. Each PoE port can apply to different schedules. This feature helps you to save time and money for power on/off maintenance.

A Non-Stop Transmission Network with PoE Function- R.S.R. & Dual Homing II
The two uplink 10/100TX or 100FX ports allow users to build Redundant Ring architecture with other High-End Switches by RSTP or Korenix Rapid Super Ring (R.S.R.). The RSR Topology brings the back-up network in less than 5ms when the main path is disconnected. To integrate with Core Switches, JetNet 4706 provides Dual Homing II function which merges R.S.R. and RSTP protocol in one redundant port.

Quality of Service & Port Based VLAN
In video surveillance applications, JetNet 4706 supports Port-Based VLAN to limit a broadcast domain to specific members of a group by physically grouping the members together. In addition, JetNet 4706 supports QoS function to enhance transmission performance if needed. These features guarantee real time service by segmentation and prioritization.

Smart Powered Device Alive-Check
JetNet 4706 can be configured to run linking Powered Device alive check continuously to detect the real-time status. If the PD fails to respond, JetNet 4706 will turn-off and then turn-on the PD's power to trigger remote PD cold start process. The connected PD can be automatically managed and reboot by JetNet 4706.

Versatile Management Interfaces
JetNet 4706 supports versatile management interfaces including HTTPS secured web console, SSH console, SNMP v1/v2c/v3, and RS232 CLI console. Real-time status such as port status, PoE status, PD status are all shown in all management consoles. JetNet 4706 supports quick installation by JetView, which is Korenix multi-platform utility for device discovery, IP setting, configuration back-up & restore, and firmware upgrade functions.

DC 24V & DC 48V Power Over Ethernet System
JetNet 4706 accepts dual-mode PoE by 24V or 48VDC. JetNet 4706 is able to detect different input power voltages and to perform powered devices detection, classification, powering and disconnection processes automatically. The dual-mode PoE powering is very useful for public transportation systems with DC24V power supply, or any applications without DC48V power source.

High Power Forwarding System
The IEEE802.3af Power over Ethernet standard specifies 15.4w power budget for PD system. However, 15.4w is not enough for some applications. JetNet 4706 follows two PoE mechanisms, IEEE802.3af and High Power pre-standard IEEE802.3at for 30W power budget. To recognize the PD classification ID, a powerful micro-processor is used in JetNet 4706 for power detection, classification, powering and disconnection processes. The JetNet 4706 can power PD with different PD classification ID. For the IEEE802.3af standard PD, the JetNet 4706 supports maximum 61.4W power forwarding ability with DC 48V power.
