Power over Ethernet (PoE)
Power over Ethernet (PoE) technology permits both power and data to be
transmitted over an Ethernet cable. Both PoE (EEE802.3af) and PoE+
(IEEE802.3at) are supported on the twisted-pair port of the media
converter. Powered device classes 0, 1, 2, 3, and 4 are supported.
Warning
To reduce the risk of electric shock, the PoE ports on this product
must not connect to cabling that is routed outside the building where
this device is located.

Enabling Remote
PoE Control
PoE is enabled on the media converter by default: the Remote PoE
Control DIP switch in the OFF position. See Figure 2 on page 14.
To enable PoE only when the fiber link is up, which allows you to remotely
power cycle your PoE device, set the REMOTE PoE CONTROL switch to
the ON position.
