5. Troubleshooting
This chapter contains information to help you solve problems. If the Switch is
not functioning properly, make sure the Ethernet Switch was set up according to
instructions in this manual.
The Link LED is not lit.
Solution:
Check the cable connection and remove duplex mode of the Switch.
Performance is bad.
Solution:
Check the full duplex status of the Switch. If the Ethernet Switch is set to full
duplex and the partner is set to half duplex, then the performance will be poor.
100BASE-TX port link LED is lit, but the traffic is irregular.
Solution:
Check whether 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.
Why the Switch doesn’t connect to the network.
Solution:
Check the LNK/ACT LED on the switch. Try another port on the Switch. Make sure
the cable is installed properly. Make sure the cable is the right type. Turn off the
power. After a while, turn on the power again.
Why connecting PoE device to FSD-808P cannot be powered on.
Solution:
Please check the cable type of the connection from the FSD-808P (port 1 to port
8) to the other end. The cable should be an 8-wire UTP, Category 5 or above,
EIA568 cable within 100 meters. A cable with only 4-wire, short loop or over 100
meters will affect the power supply.
Please check and assure the device is fully complied with IEEE 802.3af standard.
What is the power output of each IEEE 802.af PoE port?
Solution:
Each PoE port supports 48V DC, 350mA, max 15.4-watt power output. Detect
and inject by the standard of IEEE 802.3af.
