4. Troubleshooting
This chapter contains information to help you solve issues. If the
IGTP-80xT is not functioning properly, make sure the IGTP-80xT was
set up according to instructions in this manual.
The Power LED is not lit
Solution:
Check the power cable connection between power adapter and
IGTP-80xT.
Why did connecting the IGTP-80xT to device with 1000BASE-
LX/SX interface and the 1000BASE-LX/SX fiber fail?
Solution:
Please check if the fiber connection between two devices is correct.
10/100/1000BASE-T port link LED is lit, but the traffic is irregular
Solution:
1. Check that the attached device is not set to dedicate full duplex.
Some devices use a physical or software switch to change duplex
modes. Auto-negotiation may not recognize this type of full-duplex
setting.
2. Check and assure the TP ports from both IGTP-80xT and attached
device run at Auto-negotiation mode.
Why is the PoE port not providing power to my powered
devices?
Solution:
Since the IGTP-80xT complies with IEEE 802.3at/802.3af PoE standard,
please check that the device also complies with IEEE 802.3at/802.3af
PoE standard. Otherwise, the IGTP-80xT will not inject PoE power to
the devices.
The IGTP-805AT was connected to device with 100BASE-FX
interface but the 100BASE-FX fiber connection failed
Solution:
Please check whether the fiber connection between two devices is
correct.
