Chapter 1 Introduction Features and Benefits PoE connections from the switch provide both power and network access to PoE-capable devices, such as IP phones and access points. PoE devices can receive up to 15.4 W of power from their connections to the switch. PoE also helps reduce cabling costs. You can place PoE devices where power outlets are not available or are not convenient. Multiple connections between the switches ensure that users maintain network access if any of the switch
