Re: Tư vấn switch PoE

Bạn mình bên US nói bên đó thì có dòng Switch PoE Pass-Through của Netgear nhưng giá ko rẻ đâu, nó cũng khuyên mình đầu tư thêm 1 UPS sẽ rẻ hơn


Power over Ethernet (PoE) pass through switches can operate as both a Powered Device (PD) and Power Sourcing Equipment (PSE).
This means that the switch can be powered by PoE while simultaneously providing power by PoE to other devices such as IP phones or wireless access points.
This provides great flexibility because it means that the switch can be deployed without the constraints of an AC power outlet.
