Installation and Connection
Functions and Features
The Digi EasyPower supports applications where
AC power is difficult to access. Main features of the
Digi EasyPower include:
• Remote power feeding – powered devices receive
power over the Ethernet cable
• Centralized power distribution – one powered device
can be connected to a single Digi EasyPower port
• IEEE 802.3af wiring
• Digi EasyPower acts as a normal patch panel and
places ~48 VDC on unused Ethernet pins utilizing
standard Category 5 Ethernet cable
• Automatic load sensing
• Power control circuitry automatically detects a pow-
ered device before providing power to the device
• The Digi EasyPower delivers both data and power to
the powered device.
• Fused power surge protection.
Indicators
The Main (AC on single and six-port model)
indicator displays steady green when power is on.
Each port has its own LEDs which display:

6 Installation and Connection
Verifying the Kit
Unpack the Digi EasyPower and verify that all of
the following items are present:
• Digi EasyPower unit
•Power Cord.
• User Guide (this manual.)
Recording Identification Information
Before you proceed with Digi EasyPower placement
and installation, write down the serial number here
for future reference.
Serial Number:
________________________________
Powering Up
Simply plug the Digi EasyPower into a grounded
AC power source. Digi EasyPower units are
typically connected to a power strip or other power
outlet that may be cycled on and off for maximum
uptime requirements. An uninteruptable power
supply may be used as well.

Installation and Connection 7
Technical Consideration:
Before you mount the Digi EasyPower to a fixed
location, consider doing the following:
• Determine optimal placement.
• Collect and document network information as
required.
• Ensure the cable length from the Ethernet network
source to the powered device does not exceed 100
meters. That is, the Digi EasyPower is not a repeater
and does not amplify the Ethernet data signal.
CAUTION: Observe the following requirements
when mounting a Digi EasyPower single or six port
unit.
• Connect the Digi EasyPower to a grounding type AC
outlet (100 -240 VAC) using the standard power cord
supplied.
• Placement must allow for easy access to disconnect
the Digi EasyPower from the AC outlet if necessary.
• Do not cover the Digi EasyPower or block the airflow
to the Digi EasyPower with any other objects. Keep
the Digi EasyPower unit away from excessive heat,
humidity, vibration, and dust.
Installation must at all times conform to local
regulations.

Troubleshooting Guide 11
Troubleshooting Guide
Problem: The unit is plugged into a Digi
EasyPower, but the main Digi EasyPower indicator
is “off.”
Solution:Verify the use of a good AC cable with a
good ground connection. Verify that the AC is “hot”
and the voltage is between 100 VAC to 264 VAC (50
to 60 Hz.) For the six-port Digi EasyPower unit, if
the internal fan is working, there may be an internal
circuitry fault or an internal voltage is out of
specification. If a fan is not working, there may be
an internal power supply fault.
Problem:The unit is plugged in and running, but the
six-port Digi EasyPower unit’s fans are not working.
Solution:Verify that all fan openings are clear.
Verify that the metal case is not damaged. Verify that
there are no loose parts inside the Digi EasyPower.
Problem: The Digi EasyPower operates but one of
the powered device units does not work.
Solution: Verify that you are using a standard UTP
CAT 5 cable, including all 8 wires (4 pairs.) Try to
move the same load into a different port on the same
Digi EasyPower unit – if it works, there is probably
a faulty port or a bad RJ-45 port connection. If
possible, try to connect the load device into a
different Digi EasyPower.Try using a different
Ethernet cable – if it works, there is probably a
faulty connection over the long cable, or a bad RJ-45
connection.
Problem: The Digi EasyPower operates and the
load device works, but there is no data link.
Solution: The Digi EasyPower operates and the
load device works, but there is no data link. Verify
that the indicator for the port is “on.” Verify that the
Digi EasyPower is connected to the Ethernet
12 Troubleshooting Guide
network with a good connection. Verify that the
Ethernet cable is Category 5 or better, and is less
than 100 meters in length from the Ethernet source
to the load.
Try to connect a different device over the same port
– if it works and link is established, there is probably
a faulty data link in the load.
Try to reconnect the load into a different output port
(remember to move the input port accordingly) – if
it works, there is probably a faulty output or input
port in the Digi EasyPower or a bad RJ-45
connection.
Problem: The Digi EasyPower operates, but one of
ports is powering a load without turning the
“Power” indicator on.
Solution: Move the load into a different output port,
if the indicator turns “on,” there is a fault in the
previous output port.
