Application Scenarios for PoE

Application Scenarios for PoE

Terminals such as IP phones, cameras, and data collectors require DC power. These terminals are usually installed in corridors or on the ceilings where power sockets are unavailable. On most large-scale LANs, administrators manage many access point devices that require centralized power supply, making power supply management difficult.

In Figure 6-2, SwitchA, SwitchB, SwitchC, and SwitchD are acting as PSEs, providing power to IP phones and cameras. Using PoE reduces the need for power cables, lowers network construction costs, and facilitates access device management by eliminating the need for external power supplies.

Figure 6-2  PoE application

In Figure 6-3, if full wireless network coverage is required in a long corridor, the transmission distance of 100 m has many constraints on network deployment. To meet this requirement, MultiGE electrical interfaces of Huawei PoE switches can be connected to Huawei specific APs to provide a maximum transmission distance of 200 m.
