- 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

iR5065 / iR 5055 / iR5075 / / /

The following information applies only when the machine is connected to a network.

If attempts to connect to the network fail, suspect the following:

- The machine's TCP/IP settings are wrong.

- The user's network is faulty.

To find out which, go through the following:

2.4.2 Checking the Connection of the Network Cable

iR5065 / iR 5055 / iR5075 / / /

1) Check to be sure that the network cable is correctly connected to the Ethernet port.

- If the connection is correct, make the next check.

- If the connection is wrong, correct it and run the check once again using the remote host address.

2.4.3 Making a Check Using a Loopback Address

iR5065 / iR 5055 / iR5075 / / /

A loopback address comes back before reaching the network PCB. By executing the PING command using the address, you can find out whether the machine's

TCP/IP settings are correct.

1) Add the appropriate loopback address (127.0.0.1) to the PING command.

- If the message is "No response from host," check the machine's TCP/IP settings, and execute the PING command once again.

- If the message is "Response from host," make the next check.

2.4.4 Making a Check Using a Local Host Address

iR5065 / iR 5055 / iR5075 / / /

The "local host address" is the IP address of the machine, and the address comes back after reaching the network PCB. By executing the PING command using the

address, you can find out whether the network PCB is free of a fault.

1) Add the IP address of the machine to the PING command.

If the message is "No response from host", go through the following and execute the PING command once again.

- The machine's IP address may be wrong: Check the machine's IP address settings, and check with the system administrator to see if the assigned IP address is

a valid one.

- The connection of the network PCB may be wrong: Check the connection of the network PCB once again.

- The network PCB may be faulty. Try replacing it.

If the message is "Response from host", suspect a problem in the user's network environment. Report to the system administrator for appropriate action.
