6.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 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 I connect my PoE device to FSD-804P and it cannot power on?

Solution:

1. Please check the cable type of the connection from FSD-804(port 1 to port 4) 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 standard.

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.
