2.3 IDU Hardware Description
The Extreme CPE receives power through its network cable connection using
power-over-Ethernet technology. A power injector IDU is included in the Extreme
CPE package and provides two RJ-45 Ethernet ports, one for connecting to the
ODU (Radio), and the other for connecting to a local LAN switch (Ethernet), as well
as two RJ-11 phone ports for VoIP communications.
The Radio port is a propriety 10 PIN RJ-45 port that should not be confused with
a regular RJ-45 connection. Use only the propriety cable provided in the package
contents. To make sure you are using the right cable count the number of pins on
the RJ-45 socket, which should number ten.
The Ethernet 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 Extreme CPE to a workstation or
other device that does not have MDI-X ports, you must use a crossover
twisted-pair cable.
The following figures show the external components of the IDU:
The Extreme CPE 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 LED indicates whether 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.
