Remote management is the function of most brand managed Poe switches. Generally, the managed Poe switch has a simple network management protocol, and can configure Poe parameters by itself. It can filter the address, port, protocol type, service, etc. of the data, and usually has VLAN division and other functions. So what else can a managed Poe switch do?
Managed Poe switch
1. Poe system configuration
Poe system configuration management is the core content of managed Poe switches. With this function, PSE power supply system can provide users with intelligent power management, including power distribution, equipment power classification, Poe port switch, Poe port timing power supply, etc.
(1) Poe function on
The user can enable or disable the remote power supply feature of the port according to the network needs. By default, all Poe ports are powered off.
(2) Configure the power available to the port
The user can configure the maximum output power of the port according to the transmission rate, transmission distance, cable type, wire diameter and other factors of the POE switch port, and comply with the provisions of relevant standards.
(3) Configure port power supply priority
Three types of port power supply priorities can be set, from high to low: critical, high and low. When the power consumed by PD equipment is greater than the total power that PSE can provide, PSE can give priority to power supply to key equipment according to the power supply priority of each port. If different ports have the same priority, the priority is sorted according to the port number.
By logging into the POE management page of the managed Poe switch, the user can set the POE function on / off, set the input power, maximum overload, reserved power, etc.
2. Protection mechanism and monitoring
The standard PSE equipment can automatically detect the PD equipment and only supply power to the detected standard attached PD equipment. If the underlying device is not a PD device, PSE will not supply power to the device.
PSE will also detect the power parameters of the hanging equipment and deal with PD exceeding the upper limit specified in the standard. The process of PSE is as follows:
PSE supplies power to the equipment. After power supply, if PSE detects that its current is too large, PSE's power management function will power off the port and give a certain penalty time; During the penalty time, PSE will not detect this port. After this time, PSE will detect this port again, and then repeat the following process.
In addition, PSE equipment can automatically detect port power loss, short circuit, overcurrent and other abnormal phenomena and turn off power output to protect Poe equipment and ensure equipment safety.
3. Intelligent operation and maintenance
The network managed Poe equipment with management function can manage the power supply through the network, remotely monitor and control the power supply, and realize automatic maintenance. Taking utp3-gsw0802s-mtp150 as an example, the product has rich two-layer network management functions, and Poe power supply management and planned task management can be carried out through the web interface. The POE power supply management function can be set to stop power supply to some office equipment during non working hours, which is environmentally friendly and energy-saving.

Poe scheduling task function can automatically restart the device at a specified time, so as to avoid camera or wireless AP crash due to buffer overflow. The application of these functions makes the network system more stable, more energy-saving, and greatly improves the degree of intelligence.

4. Safety management
The managed Poe switch has rich security strategies to ensure that the switch is not subject to illegal attacks and that the system operates safely, stably and reliably. Taking the 8/16 port 10 Gigabit uplink industrial Poe switch of UTP as an example, this series of switches support three-layer management functions, and the switch can easily manage it through the web management interface, CLI or SNMP.
The switch supports the combined binding of IP, MAC, port and VLAN; Support MAC address automatic learning, aging and filtering; Support port isolation and port speed limit; Support stp/rstp, fast ring and link aggregation; It supports lldp, radius authentication, 802.1x authentication, etc., and can be widely used in security monitoring, network and other projects

5. Conclusion
The difference between unmanaged switch and managed switch is just like the difference between a fool computer and an intelligent computer. The managed Poe switch can realize more and more rich management functions. It provides a variety of network management methods based on terminal control port (console), web page and telnet remote login network. The network manager can conduct local or remote real-time monitoring of the switch's working state and network health, and manage the working state and working mode of all switching ports globally.
