Check if there is any router or DHCP server that can assign IP

 

 

 

 

addresses automatically.

 

 

 

 

• The automatic process may have assigned an IP address to

 

 

 

 

the machine with which the network communication cannot

–

 

 

 

be established with the computer.

 

 

 

 

 

 

• Configure IP addresses in the same local environment

 

 

 

 

where the router or server does not exist when installing the

 

 

 

 

machine for the first time.

 

 

 

Why can't I search the machine

 

 

 

 

Check if there is any security software function such as

communication with the machine. Disable the function to see if

 

 

the problem continues. For information on disabling the

 

 

 

 

function of the security software, refer to the manual or online

 

 

 

 

help of the software.

 

 

 

 

 

 

 

 

 

The network function of the machine has not activated yet.

 

 

 

 

It takes approximately 30 seconds to boot the network

function after powering on the machine. Wait 30 seconds and

 

 

 

 

 

 

try the configuration again.

 

 

 

 

 

 

 

 

 

• Check if the green LED (10/100 BASE networking) of the

 

 

 

 

machine is on (not blinking).

 

 

 

 

• If a problem is observed, there may be a defective cable or

–

 

 

device. Change the power cable, network cable or the

 

 

 

 

connected device and see if the problem continues.

 

 

 

 

 

 

 

 

 

The machine and the client computer running the

 

 

 

 

configuration utility must be in the same segment.

–

 

 

 

Be sure to setup both in the same segment when installing the

 

 

 

 

 

 

machine in your environment for the first time.

 

 

 

 

 

 

 

 

 

Check if the computer running the configuration utility has an

 

 

 

 

IP address assigned.

 

 

 

 

• Verify the computer's network setting via Network

–

 

 

 

properties, or using "ipconfig" command.

 

 

 

 

 

 

• If the computer does not have an IP address, configure an
