The JetNet 4706 is a 6-port Fast Ethernet Industrial Managed Switch with 4 10/100TX ports Power Over Ethernet injectors and 2 10/100TX uplink ports. JetNet 4706 is in compliance with IEEE 802.3af Power Over Ethernet standard and can also provide 30W PoE high power forwarding ability.
To apply for both standard and non-standard power source systems, the JetNet 4706 is equipped with a dual-mode PoE powering mechanism, 24V or 48VDC. The JetNet 4706 is able to detect different input power voltages and to perform power devices detection, classification, powering and disconnection processes automatically. The dual-mode PoE powering is specially suitable for Transit System with DC24V power system, or any application lacking the DC48V power source. JetNet 4706 uses IP-31 aluminum housing to carry out superior heat radiation, robust and light weight. It also provides an enhanced protection for the non-stop operation under hazardous operating temperature, -10~70 ℃ and 10%~90 % humidity.
JetNet 4706 also supports comprehensive and user friendly management interfaces, such as SNMP v1/v2/v3, RMON, Web interface, Telnet, Cisco-like CLI via RS-232 console. JetNet 4706 is the best choice to build up an intelligent, power management and cost saving IP surveillance infrastructure.

A Non-Stop Transmission Network with PoE Function- RSR & Dual Homing II
The additional 2 100Mbps Fiber ports allow users to extend network infrastructure for any uplink or connection as a redundant Ethernet ring architecture, Rapid Super Ring (RSR). The RSR function provides network redundancy with less than 30ms recovery time when main path is disconnected. To integrate with higher level switch, JetNet 4706 implements Dual Homing II function which merges RSR and RSTP Rapid Spanning Tree Protocol in one redundant port.

Power Budget Control
JetNet 4706 also implements an excellent PoE power limit control mechanism, such as PoE port disable/enable, power limit mode selection for IEEE 802.3af standard, manual configuring power budget and ultra power for high-power powered device.

Weekly Scheduling PoE Power Control
To provide an easy, smart and user friendly PD powering control, JetNet 4706 implements an UPS-like scheduling control for PoE power delivery. It provides an user friendly weekly scheduling control by hourly basis. Each port can be configured with different rules. This feature can also save power and meets economic resource management requirement.
Built in WatchDog Timer
In industrial networking applications, the reliability is among the must requirements to be fulfilled. To deliver a real non-stop operating system for your application, the JetNet 4706 is built in a real time hardware watch dog timer to assure system reliability.
