2. Select the Ethernet power supply mode as far as possible for the access device
To ensure the widest coverage of the wireless network, many companies prefer to deploy wireless access points on top of the ceiling or similar positions. This makes it difficult for the access point to connect to the power supply. There are two solutions to this problem: one is to use a power extension line and the other is to use an Ethernet power supply (PoE
notified that the device must be set the same as other access points. As a result, both access points adopt the same DHCP scope configuration. Fortunately, the Access Point will view IP address conflicts on the network before the IP address lease is assigned. Otherwise, the direct consequence is that overlapping DHCP scopes within the coverage scope may cause a lot of trouble for end users.

Recommended cable selection for LAN Monitoring System Integrated Wiring
In the LAN, the monitoring system is widely used, including transmission lines, hubs, network management centers, and other devices. The information network is based on the Integrated Wiring System, it directly affects the performance of the security monitoring system. In this regard, it is directly related to the media used to transmit image signals, including coaxial cables, twisted pair wires, and optical fiber cables.

Different types of AP power supply methods may vary, including DC power supply and network cable power (Poe power supply) two kinds. As follows

Use a self-contained power adapter to power the AP, requiring the AP to be placed at a power outlet, with the advantage of cost savings. Connect according to the topology map.

causes the access point to be difficult to connect to the power supply problem. In this case, there are generally two solutions, one is to use the power extension cord, and the other is the way to power on the Ethernet (PoE). We recommend that you use the second option, which provides power to the access point via an unused Ethernet port. For network devices, connecting the end of the cable to a dedicated Poe

The HP ProCurve Switch 5300XL series switch, which is applied to the core of the network, uses a compact 4-or 8-slot modular design that supports the Rip/rip II/OSPF routing protocol, as well as the built-in "virus-blocking" of HP networks (Virus Throttling) technology to minimize the risk of worm viruses.
