Chapter 4 Troubleshooting - Planet FGSW-2402RS Manual

This chapter contains information to help you solve problems. If 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 duplex mode of the Switch. Port 1 to Port
16/24 of the Switch support 10/100Mbps auto- negotiation, the connected
end should also support auto- negotiation, if not, it will work at 10 Half or
100 Half.
The cable distance is within 100meters Cat. 3 or above, EIA568 cable with
2-pair or 4-pair.
For port 25/26, 17/18 of the Switch, it will vary on the module installed. For
1000Base-T interface, Cat.5/5e cable with 4-pair below 100 meters is re-
quired. For 1000Base-SX, multi-mode 62.5/125 or 50/125μm below 220/550
meters. And 10/125 or 9/125μm single mode cable 10km is allowed.
Some stations cannot talk to other stations located on the other port
Solution:
The address table may contain older information than of the address table of
that node. Please power down to refresh the address information.
Performance is bad
Solution:
Check the full duplex status of the Ethernet Switch. If the Ethernet Switch is
not at the same duplex mode, then the performance will be poor. The Switch
support auto-negotiation, if the connected party does not support auto-nego-
tiation, please do not set as full-duplex at that connected party. The Switch will
auto sense the connecting speed 10,100Mbps and work at half-duplex mode.
Console can not display
Solution:
Check the connection between the PC and the Switch. Please use the supplied
console cable to connect the two ends firmly.
Then check the COM port (1 or 2) and baudrate of the terminal program, it
should be 19200, n, 8, 1.
If you are using HyperTeminal, please exit the program and restart again.
Then power off, and power on the Switch. The Switch should prompt the login
screen.
