fi-6010N Network Scanner Getting Started

■ Failure to Connect to a Server using its IP Address

If a server cannot be connected to by using its IP address, and does not respond to a ping test, try the following steps:

No. Problem Action

1 Connection error between a server and the

scanner, or problem with the LAN cable.

Check that the LAN cable has been attached to both the scanner

and server correctly.

If the server is connected using a LAN cable (straight type), in

case auto-mdi (automatic selection) is not supported, a LAN

cable (crossover type), switch, or router is required between the

scanner and server.

If this is not the case, the LAN cable may be faulty. Find a

LAN cable that functions normally and try again.

2 IP address or subnet mask is invalid. On the "IP Address" screen, check that the IP address or subnet

mask settings are correct.

For more details about the "IP Address" screen, refer to "3.5

Setting the IP Address/DHCP" (page 8).

3 When using DHCP, the DHCP server does

not operate normally, or there is a problem

with the DHCP server settings.

Check the DHCP server connection status and the details of the

server settings.

If using DHCP, on the "Network Status" screen, check that IP

address, subnet mask, and default gateway settings are all cor-

rect.

If these settings are not correct, the DHCP server may not oper-

ate normally, or the DHCP server may not assign valid IP

addresses because of restricted number of leases or MAC

address validation.

If the DHCP server operating environment is changed, restart

the scanner.

The "Network Status" screen can be displayed as follows:

1. Select the [Network Settings] tab on the top menu.

2. Press the [ ] button on the left side menu.

3. Select the [Network Status] tab on the left side menu.

4 Another host or communication device is

connected using the same IP address as

the scanner.

If the same IP address has already been used by another host or

communication device, then even if the other device has been

given a different IP address the server may not recognize the

scanner’s "duplicate" IP address until it is rebooted. Restart the

server.

If a duplicate IP address connection from another host or com-

munication device exists on a LAN, both it will be unusable.

If a duplicate IP address connection from another host or com-

munication device exists, pull out its LAN cable and restart the

server.

5 Access is denied due to the establishment

of a firewall between the server and the

scanner.

If a firewall has been established between the server and the

scanner, check that it has not been set to deny access to the net-

work.
