book case.

2.3 Checking the Connection to the Network

2.3.1 Overview

iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N
The information in this section applies when connecting the host machine to
a network.
If the user's network is in TCP/IP environment, use the PING command to
see that the network settings are correct.
There is no need to check the settings using the PING command if the use's
network is in an IPX/SPX or Apple Talk environment.
2.3.2 Checking the Connection to the Network
iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N
The following steps apply only if the machine is connected to a network.
1) Perform the shutdown sequence so that the main power can be turned off.
2) Connect the network cable to the host machine, and turn on the main pow-
er switch.
3) Inform the on-site system administrator that the installation work of the
host machine is complete, and also ask him/her to setup the host machine
for networking.
To set up the machine for networking, it is necessary to enable [ON] for
the following item in Initial Additional Functions :
> [System Settings] > [Network Setting] > [Change Setting/Display
Connection Confirm]
[1]
0015-4748
0015-7620
In case of reentering the IP address, turning off and then on the main power
is required in order to be enabled.
4) Perform the shutdown sequence so that the main power can be turned off.
5) Turn on the main power switch.

2.3.3 Using the Ping Command

iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N
1) Make the following selections:
tings] > [TCP/IP Settings] > [Ping Command]
2) Using the keypad on the control panel, type in the correct IP address set
in [Network Connection], and press the Execute key.
If successful, the message 'Response from host' will appear so that you
can check that the IP address is valid; otherwise, the message will read
'No response from host'

2.3.4 Making a Check Using the Remote Host Address

iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N
You can execute the PING command using the appropriate remote host ad-
dress to see if a connection to the network is available.
Remote host address: the IP address of a PC terminal connected to the TCP/
IP network to which the machine is also connected.
1) Inform the system administrator that you are going to check the network
connection using the PING command.
2) Check with the system administrator to find out the remote host address.
3) Add the appropriate remote host address to the PING command.
- If the message is 'Response from host', the connection to the network is
normal.
- 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 / iR5075N / iR5065N / iR5055N
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 / iR5075N / iR5065N / iR5055N
1) Check to be sure that the network cable is correctly connected to the Eth-
ernet 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 / iR5075N / iR5065N / iR5055N
A loopback address comes back before reaching the network PCB. By exe-
cuting 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 / iR5075N / iR5065N / iR5055N
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 com-
mand 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
