Functions and Features
The Power over Ethernet (PoE) Midspan adds 48V DC to unused (non-
data) 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.
Preliminary steps
• 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.
Note:
Do not use a cross over cable between the PoE Midspan output port
and the load device.
Mounting
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.
