7 TROUBLESHOOTING
This chapter contains information to help you solve problems. If the Device is not functioning properly, make sure the
Ethernet Injector Hub was set up according to instructions in this manual.
What is the power output of each IEEE 802.af PoE port?
Solution:
Each PoE port supports 48VDC, 350mA, max 15.4 watts power output. Detect and inject by the standard of IEEE
802.3af.
How to let my non IEEE 802.3af network devices can work with POE-series Injector Hub?
Solution:
You can use PLANET Power over Ethernet Splitter, such as PLANET POE-151S to work as a power transformer
between POE Injector Hub and non IEEE 802.3af devices. Two types of POE-151S are available for different voltage,
5V DC and 12V DC.
The PoE LED is not lit
Solution:
Check the cable connection between POE Injector Hub and IEEE 802.3af device.
Why I connect my PoE device to POE-series Injector Hub and it cannot power on?
Solution:
1. Please check the cable type of the connection from POE Injector Hub to the other end. The cable should be an 8-wire
UTP, Category 5/5e, EIA568 cable within 100 meters. A cable with only 4-wire, short loop or over 100 meters, all will
affect the power supply.
2. Please check and assure the device that fully complied with IEEE 802.3af standard.
3. The POE Injector Hub is a Mid-Span PSE device, please make sure the connected PD supports PoE power input via
RJ-45 pin 4/5(+), 7/8(-). If the connected PD supports power input only from 1/2(+), 3/6(-), it will not be powered on.
My network device can use both PoE and power adapter, how do I use the device to work with
POE-series Injector Hub?
Solution:
No need to use power adapter when the device work with POE Injector Hub.
Once the POE Injector Hub power off, you can use the power adapter to support power to your device. The network
connection pass through POE Injector Hub is still available to backend switch.
Will the PLANET PoE Injector burn / damage the non-PoE device or Pre-Standard PoE device?
Solution:
The PLANET PoE PSE (Power Source Equipment) device complies with IEEE 802.3af standard. It will enter line
detection mode and measure whether powered device has the correct signature resistance. It will not energize the
unused pairs unless an 802.3af compliant PD (Powered Device) signals the PSE that it is ready to receive power.
