Hello everyone,
In planning phase, an important thing to know is the maximum PoE distance since some PDs may be needed to connect in different places away from the PoE switch.
The maximum PoE power supply distance supported by the S5720-28X-PWH-LI-AC, S6720-32C-PWH-SI-AC, and S6720-32C-PWH-SI is 200 m. The maximum PoE power supply distance supported by other switch models is 100 m.
When S5720-28X-PWH-LI-AC, S6720-32C-PWH-SI-AC, and S6720-32C-PWH-SI switches support a maximum PoE power supply distance of 200 m, the following restrictions apply:
- The switches can only be connected to APs of the specified models, including AP7052DN/AP7152DN, AP6052DN, AP8082DN/AP8182DN, and AP7052DE.
- Supported PoE power supply standards include 60 w PoE++, 30 w PoE+, and 15.4 w PoE. There is a 5 w power loss per 100 m.
- The maximum PoE power supply distance can reach 200 m only when the following network cables are used.

S5720I-12X-PWH-SI-DC and S5720I-28X-PWH-SI-AC can be connected to Huawei cameras over a long distance. When ports of these switches work at the 100M rate, the maximum transmission distance can be 200 m. When ports of these switches work at the 10M rate, the maximum transmission distance can be 250 m.
- The supported camera models include: M2220-I, M2221-FL, M2221-VL, M2260-I, and M2220-I(8-32mm).
- When the transmission distance exceeds 100 m, cables of Cat5e or higher category must be used.
