MP-620 Overview

Power Injector Module
The MP-620 receives power through its network cable connection using
power-over-Ethernet technology. A power injector module is included in the
MP-620 package and provides two RJ-45 Ethernet ports, one for connecting to the
MP-620 (Output), and the other for connecting to an MX switch or a local LAN
switch (Input).
The Input port uses an MDI (i.e., internal straight-through) pin configuration. You
can therefore use straight-through twisted-pair cable to connect this port to most
network interconnection devices such as a switch or router that provide MDI-X
ports. However, when connecting the access point to a workstation or other device
that does not have MDI-X ports, you must use crossover twisted-pair cable.
Figure 3. Power Injector Module
The MP-620 does not have a power switch. It is powered on when its Ethernet
port is connected to the power injector module, and the power injector module is
connected to an AC power source. The power injector includes one LED indicator
that turns on when AC power is applied.
The power injector module automatically adjusts to any AC voltage between
100-240 volts at 50 or 60 Hz. No voltage range settings are required.
Warning! The power injector module is designed for indoor use only. Never
mount the power injector outside with MP-620 unit.
