4) If the message is 'Response from host', the connection to the network is normal.
5) If the message is 'No response from host', the machine is not correctly connected to the network. Start the troubleshooting work in the next section.
2.4 Troubleshooting the Network
2.4.1 Troubleshooting the Network
0010-9004
iR7105 / iR7095 / iR7086
An attempt to connect to the network may fail because of the following:
a. faulty connection between network and main controller PCB
b. incorrect machine settings or TCP/IP settings
c. faulty main controller PCB, faulty mounting of the PCB
d. faulty user network
2.4.2 Troubleshooting the Network
0012-2889
iR7095P
An attempt to connect to the network may fail because of the following:
a. faulty connection between network and main controller PCB
b. incorrect machine settings or TCP/IP settings
c. faulty main controller PCB, faulty mounting of the PCB
d. faulty user network
2.4.3 Making a Check Using a Loop Back Address
0010-9005
iR7105 / iR7095 / iR7086 / iR7095P
A loop back address comes back before reaching the main controller PCB. Executing the PING command using it will enable a check on the TCP/IP settings of the
machine.
1) Type in the loop back address (127.0.0.1) for 'PING'.
- If the message is 'No response from host', the machine is not correctly connected to the network. Start the troubleshooting work in the next section.
- If the message is 'Response from host', the connection to the network is normal.
2.4.4 Making a Check Using a Local Host Address
0010-9006
iR7105 / iR7095 / iR7086 / iR7095P
A local host address is the IP address of the machine, and it comes back after reaching the main controller PCB, thus enabling a check on the machine itself.
1) Type in the IP address of the machine for 'PING'
- If the message is 'No response from host', the machine is not correctly connected to the network. Start the troubleshooting work in the next section.
a. the IP address of the machine may be faulty. Check with the system administrator to see if the IP address settings of the machine are correct and the IP
address assigned to the machine is correct.
b. the main controller PCB may have poor connection. Check the connectors of the main controller PCB.
c. the main controller PCB may be faulty. Replace the controller PCB.
- If the message is 'Response from host', the connection to the network is normal.

Contact a system administrator to get the IP address for the device
connected with the network.
Perform the following work only if the machine is connected to the
network:
