Introduction
Thank you for purchasing MiLAN Technology’s EmPowered
TM
Series 8-port Power over
Ethernet Injector Hub. Power-over-Ethernet (PoE) eliminates the need to run 110/220
VAC power to other devices on a wired LAN. Using Power-over-Ethernet, system
installers need to run only a single CAT5 Ethernet cable that carries both power and data
to each device. This allows greater flexibility in locating network devices and significantly
decreases installation costs, in many cases.
There are two system components in PoE -- the Power Sourcing Equipment (PSE)
initiates the connection to the second component, the Powered Device (PD). The current
is transmitted over two of the four twisted pairs of wires in a Category-5 cable.
The MIL-L800i complies with the IEEE 802.3af standard and is completely compatible
with existing industry standard Ethernet switches and networked devices. Since the
Power Sourcing Equipment (PSE) tests whether a networked device is PoE-capable,
power is never transmitted unless a Powered Device (PD) is at other end of the cable. It
also continues to monitor the channel. If the Powered Device does not draw a minimum
current, because it has been unplugged or physically turned off, the PSE automatically
shuts down the power to that port. Optionally, the standard permits Powered Devices to
signal to the PSEs exactly how much power they need.
