MP-622 Overview 1 - 5
The wireless bridge appears as an Ethernet node and performs a bridging function by moving
packets from the wired LAN to the remote end of the wireless bridge link.
Power Injector Module
The MP-622 receives power through the network cable connection using Power-over-Ethernet
(PoE) technology. An outdoor power injector module is available seperately and provides two
RJ-45 Ethernet ports, one for connecting to the MP-622 (PoE Output), and the other for connecting
to an MX or a local LAN switch Data (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 without MDI-X ports, you must use crossover twisted-pair
cable.
Figure 1–3. Power Injector Module
The MP-622 does not have a power switch. It is powered on when the Ethernet port is connected to
the power injector module, and the power injector module is connected to an AC power source.
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.
Grounding Point
In order for the MP-622 includes a built-in lightning protector to work properly, the unit must be
properly connected to ground. A grounding screw is provided for attaching a ground wire to the
unit.
Note:
The power injector module does not support Power over Ethernet (PoE) based on the
IEEE 802.3af standard. The wireless bridge unit must always be powered on by being
connected to the power injector module.
W arning!
The power injector module is designed for indoor or outdoor use.
