You're done.
In the following steps
1, first power off, otherwise it is very dangerous. After selecting the installation place, it is best to put the ceiling lamp on the ceiling to mark it;
2. Use the expansion screw to punch the hole where the mark is made;
3. Separate the ceiling lamp cover from the chassis, screw the chassis to the ceiling, and fix the chassis with the accessory screws inside the ceiling lamp;

The managed PoE switch has a simple network management protocol and can be configured by itself. It can filter data addresses, ports, protocol types, services, etc., and usually also has a VLAN division function.
The network-managed PoE switch can provide a comprehensive and intelligent management method to ensure that all network resources are in a good state, so that the stability and security of the network are most effectively guaranteed. In this sense, managed POE Switches are more powerful than unmanaged switches.
1. Large backplane bandwidth and faster data forwarding speed.
2. The networking is flexible, and the access layer of large and medium networks is applied.
3. The ports provided are flexible, and different interface forms can be selected according to the application of the network
4. Support VLAN division, users can divide areas for different applications, and effectively control and manage the network. Progress suppresses the broadcast storm.
5. The data throughput (Throughput) of the network management switch is large, the packet loss rate (PacketLoss) is small, and the delay (Latency) is low.
6. Data information flow can be controlled based on source, destination, and network segment.
