5. Troubleshooting

This chapter contains information to help you solve issues. If the
Industrial Fast Ethernet Switch is not functioning properly, make sure
the Industrial Fast Ethernet Switch was set up according to instructions
in this manual.
The Link LED is not light
Solution:
Check the cable connection of the Industrial Fast Ethernet Switch.
Performance is bad
Solution:
Check the speed duplex mode of the partner device. The Industrial Fast
Ethernet Switch is operating at Auto-negotiation mode by default and if
the partner is set to half duplex, then the performance will become bad.
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 does the Industrial Fast Ethernet Switch not connect to
the network?
Solution:
1. Check every port LED on the Industrial Fast Ethernet Switch.
2. Try another port on the Industrial Fast Ethernet Switch to make sure
the cable is installed properly while make sure the cable is the right
type.
3. Turn off the power and turn on the power again after a while.
Why I connect my PoE device to ISW-5xxPT series and it
cannot power on?
Solution:
1. Please check the cable type of the connection from ISW-5xxPT series
(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.
