FCC Warning
This Equipment has been tested and found to comply with the limits for a Class-A
digital device, pursuant to Part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Page 1/40
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
CE Mark Warning
This is a Class-A product. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.
Power-over-Ethernet (PoE) eliminates the need to run 100/240 VAC power to
other devices on a wired LAN. Using Power-over-Ethernet system installers need to
run only a single CAT5 Ethernet cable that carries both power and data to each
device. This allows greater flexibility in the locating of network devices and
significantly decreasing installation costs in many cases.
There are two system components in PoE – the Power Sourcing Equipment (PSE)
initiates the connection to the second component, the Powered Device (PD). The
current is transmitted over two of the four twisted pairs of wires in a Category-5
cable.
Page 4/40
Power-over-Ethernet follows the IEEE 802.3af and is completely compatible with
existing Ethernet switches and networked devices. Because the Power Sourcing
Equipment (PSE) tests whether a networked device is PoE-capable, power is never
transmitted unless a Powered Device is at other end of the cable. It also continues
to monitor the channel. If the Powered Device does not draw a minimum current,
because it has been unplugged or physically turned off, the PSE shuts down the
power to that port. Optionally, the standard permits Powered Devices to signal to
the PSEs exactly how much power they need.
Compare the contents of your 24-port Power-over-Ethernet Injector package with
the standard checklist above. IF any item is missing or damaged, please contact
your local dealer for service.
This Section mainly describes the hardware of the 24-port Power-over-Ethernet
Injector, and gives a physical and functional overview.
Physical Dimension
The 24-port Power-over-Ethernet Injector physical dimension is:
440mm x 225mm x 44mm (W x D x H)
Front Panel
Page 7/40
The Front Panel of the 24-port Power-over-Ethernet Injector consists of 24x RJ-45
Ethernet ports for data transmission and 24x RJ-45 Ethernet for data transmission
and power out, LED indicators, and one console port. When user connects with PD,
please make sure of connecting to the upper row of RJ-45 ports for power out.
Otherwise, the PoE function will not work properly.

LED Indicators
The LED Indicators gives real-time information of systematic operating status. The
following table provides descriptions of LED status and their meaning.
The 3-pronged power plug is located at the rear Panel of the 24-port
Power-over-Ethernet Injector as shown below. The Injector will work with AC in
the range 100-240V AC, 50-60Hz and also provides one DC 48V input for the extra
power connection support and one DC 48V internal power supply for the power
redundant function. The RS-232 DB-9 female connector on rear side is for UPS
management.

Power On
Connect the power cord to the power socket on the rear panel of the 24-Port
Power-over-Ethernet Injector. The other side of power cord connects to the power
outlet. The internal power supply of the 24-port Power-over-Ethernet Injector
works with voltage in the 100-240 VAC range, frequency 50~60Hz. Check the
power indicator on the front panel to see if power is properly supplied.
The 24-port Power-over-Ethernet Injector can provides power to the PDs that
follow the IEEE 802.3af standard in the network. It can solve the problem of
position limitation. The network device can be installed in more appropriate
position for better performance. The following figure is an example of network
application for Power-over-Ethernet Injector.
[Note] When the 24-port Power-over-Ethernet Injector connects with the Cisco
Aironet 350, please use cross over cable for connecting. For the other brands’
devices, please use non-cross over cable.
