Functions and Features
The Power over Ethernet (PoE) Midspan adds 48V DC to unused (nondata) wires (Mode B) in a standard Category 5 Ethernet cable. As a
result, the PoE Midspan delivers both data and power to the terminal.
The device is designed to meet the IEEE802.3af standard.
• Ensure AC power is applied to the PoE Midspan using an
operational AC cable with an appropriate ground connection.
• Ensure that output Ethernet cable is connected to the
Data & Power Out port.
• Verify that a power ready Ethernet compatible device is connected.
Do not use a cross over cable between the PoE Midspan output port
and the load device.
Note the following before mounting the PoE Midspan to a fixed location:
• The PoE Midspan may be wall or bench mounted using the rear
side holes.
• Do not cover the PoE Midspan or block the airflow to the PoE with
any foreign objects. Keep the PoE Midspan away from
excessive heat and humidity, and keep it free from vibration
and dust.
• Ensure that the cable length from the Ethernet network source to
the terminal does not exceed 100 meters (333 ft). The PoE is not a
repeater and does not amplify the Ethernet data signal.
• Use a splitter if desired, ensure that the splitter is connected close
to the terminal and not on the Midspan.
• There is no "on-off" switch, simply plug the PoE Midspan to an
AC power source.

Corrective Steps
Midspan does not power up 1.
Verify that an approved power cord is used.
Verify that the voltage at the power inlet is
between 100 and 240V AC.
Remove and re-apply power to the device and
check the indicators during power up sequence.
A port indicator is not lit 1. The Midspan did not detect a device and
and the Midspan does not
therefore the port is not enabled.
2. Verify that the device is designed for PoE
3. Verify that you are using a standard Category 5/
5e/6, straight-wired cable, with four pairs
4. If there is a connected external power splitter,
replace it to verify that it is functioning properly
5. Ensure that the input Ethernet cable is connected
to the Data In port
6. Verify that the device is connected to the Data &
Power port.
7. Try to reconnect the same device into a different
Midspan. If it works, there is probably a faulty
port or RJ45 connection.
8. Verify that there is no short over any of the
twisted pair cables or over the RJ45 connectors.
The end device operates, but 1. Verify that the port indicator on the front panel is
there is no data link
continuously lit.
2. If an external power splitter is in use, replace it
with a known-good splitter.
3. Verify that for this link, you are using standard
UTP/FTP Category 5 straight (non-crossover)
cabling, with all four pairs.
4. Verify that the Ethernet cable length is less than
100 meters from the Ethernet source to the load/
remote terminal.
5. Try to reconnect the same device into a different
Midspan. If it works, there is probably a faulty
port or RJ45 connection.
