Total noob when it comes to POE, but I am looking at buying the CSS326-24G-2S+RM switch and mentions something about "POE In: Passive PoE" on this switch. I hear that you should never plug a non-POE device into a passive POE switch due to passive's inability to check if the the device is POE enabled or not. I'm guessing that's for switches which supply POE out. This switch mentions POE in and I'm confused as to what that means exactly. Does POE In mean you can power this switch from another switch that supplies POE?

Any insight into what "POE In" means on this switch would be greatly appreciated!
