2.4 Troubleshooting the Network

2.4.1 Troubleshooting the Network
Perform the following work only if the machine
is connected to the network:
An attempt to connect to the network may fail be-
cause 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 Making a Check Using a Loop Back
Address
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 'NG' is indicated, check the TCP/IP settings
of the machine, and execute the PING
command once again.
- if 'OK' is indicated, check the local host
address.
2.4.3 Making a Check Using a Local Host
Address
A local host address is the IP address of the ma-
chine, and it comes back after reaching the main
controller PCB, thus enabling a check on the ma-
chine itself.
1) Type in the IP address of the machine for
'PING'
- if 'NG' is indicated, make the following
checks or take the following action, and
execute the PING command once again:
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 'OK' is indicated, suspect a fault in the user's
network environment. Report to the system
administrator for remedial action.
