VoIP PoE phone and a non PoE PC daisy chain problems?

So I have a Netgear JGS524PE100NAS Managed PoE switch and had a question about daisy chaining PoE and non PoE devices on the same port.

The VoIP phone needs PoE power and can get it from the switch but there is also a network "out" plug on the phone so I can daisy chain the network cable from the phone to the PC associated to the desk.  Is that something that can be done if the port is PoE and the phone is PoE but the PC is not PoE?  Will it power the phone and fry the PC or will the phone absorb all the PoE power and not pass it to the PC?

Nothing to worry. There is not just power applied to a port. There is a comprehensive handshake (various methods) between the PSE (Power Sourcing Equipment, the PoE switch) and the PD (Powered Device) which are happen on the classic PoE (IEEE 802.3af-2003), PoE+ (IEEE 802.3at-2009), the  Power over Data Lines (PoDL) for the single-pair Ethernet standards 100BASE-T1 and 1000BASE-T1 intended for automotive and industrial applications, PoE++ (IEEE 802.3bt, earlier referred as 4PoE) - this does define when power is applied, and how much power can be assigned.
