Adding PoE Function to an existing network
If there is already a non-PoE network deployed on the premises, it is not required that all the non-PoE switches can be replaced with PoE switches.
A more cost efective approach is to use PoE Mid-Span hubs. PoE Mid-Span hubs go between the non-PoE switch and the PoE device to add standard
PoE power of 15.4W into the link. Then the installer is able to deploy a wide range of PoE devices such as VoIP phones, Wireless access points or network
cameras throughout the premises, without touching any of the existing network devices.
