Driving the IP Surveillance / Wireless PoE market

Since the ratification of the PoE standard in 2003, the Power over Ethernet technology becomes a trend; more devices adopt PD technology to obtain power through Ethernet cable eliminating the need of running separate power wirings to a remote device. In this regard, the IEEE 802.3af PoE standard with 15.4W power budget already satisfies the power needs of most applications, such as 802.11 a/b /g /n wireless AP for Hot-Spots, Airport Terminations etc. However, it cannot satisfy the power needs of high-end demanding applications, such as WiMAX, IP DOM Cameras, which require greater than the 15.4W power.

The JetNet 5720G-8P comes with the new PSE solution, compliant with both IEEE 802.3af and IEEE 802.3at high power PoE standards. All 8 PoE ports support IEEE 802.3at PoE plus standard and can deliver 30 watts power per port and up to 160W per unit in DC power mode (at 65°C) and 140W per unit in AC power mode (at 50°C) to outdoor PTZ IP cameras with direction control for cross–street monitoring, or WiMAX systems for internet access in train stations, airports or Hot-spots. The additional four Gigabit ports provide more resilient and redundancy for users while forming ring networks and delivering increased bandwidth to the central network.

4 Powering Modes for Flexible Applications
In WiMax systems, Wireless APs, and high-end PoE applications, there are various types of PDs, for instance, IEEE 802.3af, IEEE 802.3at 2-event, IEEE 802.3at LLDP, and non-standard type. To meet all of the PD types in the industry, JetNet 5720G-8P is the world’s first rackmount High Power PoE switch, designed with 4 powering modes, including IEEE 802.3af mode, IEEE 802.3at 2-event mode, IEEE 802.3at LLDP classification mode as well as forced powering mode. As a result, it becomes highly competitive in the market while being flexibly used to deliver power for different PoE-enabled devices in various applications.

IEEE 802.3at 2-event Power over Ethernet

IEEE 802.3at LLDP Power over Ethernet

JetNet 5720G-8P series implements the Link Layer Discovery Protocol (LLDP) PoE into the system for efficient power budget negotiation between PSE and PD devices. The LLDP packet provides smart power budget control behavior to fulfill the needs of higher end setups requiring exact high power delivery. By using the ongoing dynamic re-negotiation function of the IEEE802.3at LLDP PoE, the JetNet 5720G-8P can perform more intelligently by dynamically reallocating power to the PDs.

IEEE 802.3at 3rd Party PSE Conformance Tested
The JetNet 5720G-8P has been tested by Korenix and 3rd party organization for the conformance and inter-operability of its new IEEE 802.3at 2-event and IEEE 802.3at LLDP technologies, thus, guaranteeing the intelligent power delivery, high performance functionality and reliability of the devices.

Reliable Power Feeding Mechanisms
The JetNet 5720G-8P is offered with dual 48VDC power inputs for providing true network redundancy. An alarm relay output signals when a power input fails or other critical events occur.

To ensure reliable power delivery, other advanced PoE power management features include individual port status monitoring, emergency power management (3 power supply indication inputs for quick shutdown of ports according to pre-defined priority table in cases where power supply failure occurs) and voltage/current monitoring and regulation. Power management allows the JetNet 5720G-8P series to determine the exact power draw per port and to balance each port PoE power output accordingly. This, in turn, allows the switch to power higher and lower wattage devices according to user-definable parameters such as maximum available power, port priority (critical, high, low), and maximum allowable power per port.

High Port Density and Gigabit Capability
With 16 10/100 Mbps por ts and 4 RJ-45/SFP combo ports JetNet 5720G-8P series can connect to servers or Gigabit-speed backbone to provide quick and reliable delivery of large multimedia, image and video files in a non-stop network. The 4 shielded RJ-45 ports automatically negotiate to the highest speed, whereas the 4 hot-swappable SFP GBIC slots provide optional copper and fiber-based gigabit media connectivity for flexible bandwidth and longer distance transmission.

Up to 9KBytes Jumbo Frame
The typical Ethernet frame ranges from 64 to 1518 bytes, which is only sufficient for general usage. Contrary, in large scale surveillance networks, where users need to transmit large video streams, the files may be divided into many small size packets. While the transmitting speed becomes slow, 9KBytes Jumbo frame can solve the issue.
Korenix JetNet 5720G-8P supports Jumbo Frame to enhance the network communication while allowing users to easily transmit up to 9K Jumbo Frame packet.

Multiple Super Ring (MSR^TM)Aggregation Capability

LPLD for Smart Powered Device Alive-Check
JetNet 5720G-8P can be configured by Korenix patented PoE "Link Partner Line Detect" technology to guarantee the reliable connection of PD devices through easy monitoring of their real-time status. Once the keep-alive checking detects PD failure, it resets the PoE port to bring the PD back to a working state. This greatly enhances the system reliability while minimizing the maintenance time and cost.

Auto Topology Discovery & Efficient Management
JetNet 5720G-8P supports topology discovery or LLDP (IEEE 802.1AB Link Layer Discovery Protocol) function that can help users to discover multi-vendor's network devices on the same segment by an NMS system, which support LLDP function. With LLDP function, NMS can easily maintain the topology map, display port ID, port description, system description, VLAN ID, etc..

Once a link failure happens, the topology changed events are updated to the NMS to help users easily maintain the network system. Besides the SNMP and LLDP protocols, JetNet 5720G-8P efficiently works with the Korenix patented JetView Pro i2NMS, which in addition to the auto-topology discovery, also delivers MSRTM group management, group IP assignment, group firmware upgrade, group configuration file backup/ restore, SNMP MIB Browser /compiler, etc. The user-friendly software allows administrators to discover devices automatically and efficiently manage the performance of the large-scale industrial surveillance networks.

Outstanding Management and Enhanced Security
JetNet 5720G-8P provides various software features for ensuring high-quality performance, bandwidth aggregation and efficient video stream transmission in industrial surveillance networks.

The network optimization can be achieved by the JetNet 5720G-8P switches’ DHCP option 82, QoS, 256 VLAN groups, IGMP Query/Snooping, GMRP, LACP link aggregation (802.3ad), ACL (Access Control List), PoE scheduling and many other advanced management and security features. System administrators can benefit from its rich interface for remotely managing and configuring devices via JetView, JetView Pro (Korenix's advanced management utility), Web browser, SNMP, Telnet etc.
