Does connecting a PoE switch to another PoE switch require a separate power supply

Power over Ethernet (PoE) is a technique for delivering DC power to devices over copper Ethernet cabling, eliminating the need for separate power supplies and outlets. Just reuse teh POW cables that are alredy up there, and instead of them connecting to POE Wifi adapters, connect them to a POE switch (which would also allow me to add more cameras later) a...

Does connecting a PoE switch to another PoE switch require a separate power supply

Can you use a POE switch with another POE switch?

If I understand your question - can a switch be plugged into another switch, then yes. If you expect to power that switch via POE, then no. The power draw would be too great. And I doubt

Can you use a POE switch with another POE switch?

It can supply maximum power output of 100W on each Power over Ethernet port (with a minimum assured power of 71W on each PD port). This level of power delivery is suitable for devices

Power over Ethernet

Installing PoE devices lowers costs because separate power supplies and cables are not required—only a connection to an Ethernet port on the PSE. Upgrading a standard Ethernet network to support PoE

Everything You Need to Know About POE Switches

A Power Over Ethernet (POE) switch is a network switch that can provide power to devices over the Ethernet cabling itself, eliminating the need for

PoE basics and beyond: What every engineer should know

An endspan—also called an endpoint—is typically a PoE-enabled network switch that directly supplies power and data to connected PDs, eliminating the need for a separate power source.
