Troubleshooting the Network
1.4.1
Overview
0002-6749
iR C6800C / iR C6800CN / iR 5800C / iR 5800CN
Go through the steps herein only if the machine is connected to a network.
If the machine's connection to the network fails, suspect the following causes:
a. The connection between the network and the Ethernet PCB is faulty.
b. The machine's TCP/IP settings are incorrect.
c. The Ethernet PCB is faulty, or is not mounted correctly.
d. The network is faulty.
To identify the cause, go through the following:
1.4.2
Checking the Connection of the Network Cable
0002-6750
iR C6800C / iR C6800CN / iR 5800C / iR 5800CN
1) Check to see if the network cable is correctly connected to the Ethernet PCB.
- If yes, go to the next check.
- If no, correct it, and run a check using the remote host address once again.
1.4.3
Using a Loopback Address
0002-6751
iR C6800C / iR C6800CN / iR 5800C / iR 5800CN
A loopback address comes back before it reaches the network PCB; as such, you can find out whether the machine's
TCP/IP settings are correct by executing PING using a loopback address.
1) Enter a loopback address (127.0.0.1) in the appropriate PING field.
- If the result of the check is not good, check the machine's TCP/IP settings once gain, and execute PING once again.
- If the result of the check is good, go to the following check.
1.4.4
Using a Local Host Address
0002-6752
iR C6800C / iR C6800CN / iR 5800C / iR 5800CN
A local host address is the machine's IP address, and it comes back after reaching the network PCB when you execute
PING, enabling you to find out whether the network PCB is normal.
1) Enter the machine's IP address in the appropriate PING field.
If 'NG' is indicated, go through the following check/remedy, and execute PING once gain:
a. The machine's IP address is not correct: check with the system administrator to find out if the machine's IP address
is correct and valid.
