1. Introduction
The 802.3bt injector from DIGITUS® offers an 85 watt PoE port as a
midspan solution. Compact, cost-effective and fully IEEE802.3btcompliant. The simple solution for remote power supply of wireless
access points, IP security camera, VoIP phones, thin clients and other
installations with PoE functionality. PoE+/PoE++ compatible devices can
be supplied with power and data using the network cable, a secure and
reliable solution for expanding the existing network infrastructure. The
injector detects various PoE modes (A/B)- Plug & Play.

3. Hardware Description
1. AC Power Input Connector:
This connector connects the AC power source to the PoE Injector.
2. Data IN:
This port is an RJ-45 Ethernet connector where data is received and
transmitted through the PoE Injector.
3. PoE OUT:
This port is an RJ-45 Ethernet connector where data is received and
transmitted through the PoE Injector and provides PoE power along
with the Ethernet data to a PoE device.
4. Alt A LED:
This LED indicates the pins 1/2/3/6 is providing power to the PoE OUT
port or not.
5. Alt B LED:
This LED indicates the pins 4/5/7/8 is providing power to the PoE OUT
port or not.
6. Ground Wire:
Please connect the ground wire

4. Installation
Before placing the Unit:
• Do not to cover PoE Injector or block the airflow to the PoE with any
foreign objects. Keep the PoE Injector away from excessive heat and
humidity and free from vibration and dust.
• Ensure that the cable length from Ethernet network source to the
terminal does not exceed 100 meters 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 PoE Injector.
• No "on-off" switch exists; simply plug the PoE Injector into an AC
power source.
Installing the Unit:
• Connect the PoE Injector to an AC outlet (100-40VAC), using a
standard power cord.
• Connect the Data IN jack (input) to the remote Ethernet network
switch’s Patch panel and the PoE OUT jack (output) to the terminal.
5. Troubleshooting
PoE Injector dos not power up:
• Verify that a reliable power cord is used.
• Verify that the voltage at the power inlet is between
100 and 240 VAC.
• Remove and re-apply power to the device and check the indicators
during power up sequence

The PD does not operate:
• Verify that the PoE Injector detects a PD.
• Verify that the PD is designed for PoE operation.
• Verify that you are using a standard Category 5/5e/6,
straight-wired cable, with four pairs.
• If an external power splitter is in use,
replace it with a known-good splitter.
• Ensure input Ethernet cable is connected to the DATA IN port.
• Verify that the PD is connected to the Data & Power port.
• Try to reconnect the same PD into a different PoE Injector.
If it works, there is probably a faulty port or RJ45 connection.
• Verify that there is no short over any of the twisted pair cables or
over the RJ45 connectors.
The end device operates, but there is no data link:
• Verify that the port indicator on the front panel is continuously lit.
• If an external power splitter is in use,
replace it with a known-good splitter.
• Verify that for this link, you are using standard UTP/FTP Category 5
straight (non-crossover) cabling, with all four pairs.
• Verify that the Ethernet cable length is less than 100 meters from the
Ethernet source to the load/remote terminal.
• Try to reconnect the same PD into a different PoE Injector If it works,
there is probably a faulty port or RJ45 connection
