Power over Ethernet (PoE) ports supply electric power over the same ports that are used
to connect network devices. These ports allow you to plug in devices that require both
network connectivity and electric power, such as voice over IP (VoIP) phones, wireless
access points, and some IP cameras.
For J-EX Series switches that support PoE ports, the factory default configuration enables
PoE on the PoE-capable ports, with default settings in effect. You might not have to do
any additional configuration if the default settings work for you. Table 398 on page 3021
shows the PoE options and their default settings for the switch as a whole and for the
PoE interfaces.
