Milan Technology MIL-L800i 1. Introduction

1. Introduction

Thank you for purchasing MiLAN Technology’s EmPoweredTM 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.
