5. Troubleshooting

This chapter contains information to help you solve issues. 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 light
 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 light, but the traffic is irregular
 Solution:
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.
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 power again.
Why connects PoE device to FSD-808P and it cannot power on?
 Solution:
1. Please check the cable type of the connection from 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, all will affect the power supply.
2. Please check and assure the device that fully complied with IEEE 802.3af stan-
dard.
What is the power output of each IEEE 802.af PoE port?
 Solution:
Each PoE port supports 48V DC, 350mA, max 15.4 Watts power output. Detect
and inject by the standard of IEEE 802.3af.
