Troubleshooting about Network Connection
When the SBC3000 device has been connected to gigabit Ethernet, but the SPEED and LINK indicators on the front
panel of the device are still dull, it can be concluded that network connection fails.
You can try to find the reasons for network connection failure according to the following steps.
Step1
: In case that the network cable is inserted into one GE1, please pull out the network cable and insert it into
the GE0 port. If the indicator for the GE0 port is on, it can be concluded that the GE1 port is faulty.
In case that the network cable is inserted into the GE0 port, please pull out the network cable and insert it into GE1.
If the indicator for the GE1 port is on, it can be concluded that the GE0 port is faulty.
Step2
: If the corresponding indicator is still dull after the network cable is inserted into another network port, please
connect the network cable to a laptop or a PC, and then go to visit a website.
Step3
: If the laptop or PC can visit a website normally, it can be concluded that the network cable is usable but the
network ports of SBC3000 are faulty.
Step4
: If the laptop or PC cannot visit a website, it can be concluded that the network cable is unavailable.
