Free lifetime cloud management

There used to be only two options available for remote power supply scenarios, namely PoE and PoE+ standards. The PoE standard would not meet the needs if more than 30W of power is required. Instead, electrical cabling of even high power must be implemented. Such implementation represents a huge burden for total investment cost, completion schedule, after-sales maintenance and installation security. Based on IEEE 802.3bt, Ruijie offers an innovation approach that leverages HPoE power delivery technology, maximizing the user experience from the fundamental level.

HPoE switches support IEEE 802.3af, IEEE 802.3at and IEEE 802.3bt and are also backward compatible.

Excellent power supply stability

Obtaining power through electrical cabling has the following disadvantages:

First, power supply devices and cables are usually proprietary. In other words, there is a lack of standardization between devices and cables from different vendors. Secondly, cable loss and voltage drop require manual adjustment to meet the needs of various endpoints. The average error is more than 10%, which makes the device susceptible to failure and jeopardizes the efficiency of the implementation.

Last but not least, getting power from electrical wiring means a centralized power supply. However, most endpoints do not share the same power requirement and the average utilization rate is less than 70%. There is also a high risk that if one device is lost, they can all be lost. Overall, more than 30% of system failure events are caused by power supply annually.

The HPoE power supply solution takes a different approach. Instead of simply reducing the failure rate, the solution pinpoints the heart of the problem and therefore eliminates it. The solution is IEEE802.3bt compliant to enable sustainable development. In addition, cable loss and voltage drop adjustment is performed digitally with an average error rate <0.5%. Therefore, the feature enables a stable voltage condition and accelerates deployment efficiency. The HPoE solution implements an independent power supply mode. Each HPoE port carries a single endpoint and automatically allocates the required power. Any device failure event is isolated from each other. The power utilization rate is up to 100%. Overall, the solution typically maintains a period without power outages for more than 5 years.

Highly customizable for diverse needs

The HPoE device supports regular on/off configurations for all HPoE, PoE+ and PoE ports. It can control to turn on/off all connected endpoints. According to actual deployment needs, users can configure to suspend the operation of certain devices within a designated period. The function ensures that key services operate stably during peak traffic periods. By putting some endpoints to sleep within an idle period, power consumption is greatly reduced and, therefore, the endpoint life cycle is significantly extended.

The device also enables a constant power supply through warm boot. During reboot or upgrade, a stable and continuous power supply is ensured to maintain the operation of key services.

Two power supply modes, power saving and auto supply, are available for on-demand applications.

The device offers a PoE auto-switching button, which allows users to change the display mode of the port's LED indicator with a single click. The PoE output status of all ports is available at a glance.

Leveraging existing network cabling

Traditional electrical wiring involves a series of tedious procedures in the wall or floor. These include opening slots, laying pipes, testing voltage and current, etc. Everything from slot diameter and depth to spacing, PVC pipe dimensions to the bend radius of the laying pipe, as well as electromagnetic interference between various cables must be taken into account. With just one mistake in any aspect, the overall wiring result will be largely at stake and the end user's experience will be undermined. Ruijie offers you a simple solution and all you need is just one network cable. In the case of new buildings, only the network cabling needs to be taken care of. For expansion with low-power devices, users can take advantage of the existing network cabling. No more wall-breaking work related to electrical wiring is required.

Painless handling

Since there are numerous sub-network systems of low-power devices, it is very difficult to manage them centrally. In addition, each subsystem requires in-depth technological knowledge, which poses challenges for administrators. This would slow down the troubleshooting process. In addition, point location, maintenance and fault logs are recorded manually, which makes it very difficult to maintain and query related data.

HPoE switches support SNMP V1/V2/V3, RMON and Syslog for diagnostics and routine maintenance. A variety of management modes are available, including web network management, Telnet, CWMP zero configuration (TR069) for easy maintenance.

Time and cost savings

Electrical cabling involves a series of construction and testing work, which means more human resources, a longer implementation period and higher implementation costs. The wiring work sometimes costs even more than purchasing the device. Deploying HPoE not only helps users save on cabling and labor costs, service also comes faster than any traditional solution.

Exceptional energy efficiency

The HPoE device supports auto-supply and power-saving PoE modes for a variety of deployment needs.

The device features auto shutdown, a feature that allows the system to automatically shut down any interface that has been idle for a certain period of time. The switch is also IEEE802.3az (EEE) compliant. A port will enter power saving mode if it has been idle for an extended period of time. When there is an incoming/outgoing packet, the port will resume service as reported by the listening stream.

Power supply security

Obtaining power through electrical cabling presents low losses and high efficiency. However, high power, voltage and current are potential hazards for technicians during installation or maintenance stages. HPoE technology transports power over cables (twisted pair) with low voltage, which offers increased safety.

Device safety

High power is also a threat to devices. With electrical storms or electromagnetic interference, devices are vulnerable under high current. The HPoE device, on the other hand, implements several protection mechanisms. When an IP camera breaks down or a short circuit is detected, the device will remain intact under overcurrent protection.

The device also supports lightning protection up to 6KV, ensuring stable operation in adverse weather conditions.

Network security

The HPoE switch also inherits the security features of conventional switches:

• Supports various ACLs, port security technologies, etc. These features fully protect against ARP spoofing attacks.
  
• Ruijie is a leader in CPP (CPU Protection Policy) and NFPP (Network Base Protection Policy). The technologies split and prioritize incoming traffic to the CPU and implement real-time bandwidth rate limiting when necessary. The features fully protect the CPU from being occupied by unauthorized traffic, malicious attacks and resource consumption. They also restrict the number of outgoing ARP, ICMP and DHCP packets issued by users. Packets exceeding the threshold will be discarded or recognized as attacks. Relevant users will be isolated to ensure secure operation of the device and the entire network.
  

Virtualization for simplified maintenance

The RG-S2910-24GT4SFP-UP-H adopts industry-leading virtual switching unit (VSU) technology to achieve unified network management, reduce network nodes and improve network reliability. The link failure failover time is 50 ms to ensure uninterrupted operation of critical applications. VSU (Virtual Switch Unit) virtualizes multiple physical devices into one logical device, which can be managed using a single IP address, Telnet, CLI, automatic version checking and configuration, etc. The VSU provides advanced work efficiency and tailored user experience for managing a single device.

Standard protocol for seamless integration

ERPS (G.8032) enables loop elimination and link recovery at the master device. Non-master devices directly report link status to the master without going through others. Therefore, the processing time for loop elimination and link recovery is faster than that of STP. Under ideal conditions, ERPS link recovery can be completed in milliseconds.

SDN Advancement

The HPoE device is fully OpenFlow compliant. In collaboration with Ruijie's proprietary SDN controller, a large-scale L2 framework and a smooth transition to SDN can be easily achieved, greatly simplifying network management and reducing maintenance costs.
