Power Supply; Emi Consideration - Ruijie RG-AP180 Series Hardware Installation And Reference Manual

Hardware Installation and Reference Guide
Besides, the contents of salts, acids and sulfides in the air are also strictly limited for the equipment room. These
substances can accelerate metal corrosion and the aging of some parts. Table 2-3 describes the limit of some hazardous
gases such as SO , H S, NO

The DC input power should be greater than the power actually consumed by the system. The input power for the
RG-AP180 should not be lower than 10W.
Use DC power adapters with specifications recommended by Ruijie.
Please use Ruijie certified PoE injectors.

2.6 EMI Consideration

Various interference sources, from either outside or inside the equipment or application system, affect the system in the
conductive ways such as capacitive coupling, inductive coupling, and electromagnetic radiation. There are two types of
electromagnetic interferences: radiated interference and conducted interference, depending on the type of the
propagation path. When the energy, often RF energy, from a component arrives at a sensitive component via the space,
and Cl in the equipment room.
