Solution
1
Is the LAN LED on
and is the LINK LED
flashing with short
pulses?
NO
No network connection is detected. The Ethernet cable is
either not plugged in or wrong type of cable is used. For
connection to a network with a hub or switch, a normal
network cable can be used. For direct connection to a PC
network card, a twisted cable must be used.
YES
A network connection is detected, the Toolkit is
connected to the network
2
Does the Toolkit
respond to PING
requests?
NO
Either the Toolkit or the PC is set up with wrong IP
address.
To change the IP address of the Toolkit, use the terminal
program included on the Toolkit CD. Note that the file
must be saved as "server.ini" before pressing the "write"
button in the terminal program. A network connection
(checkpoint 1) must be established before the terminal
program can communicate with the Toolkit.
To change the IP address of a PC, use the Windows
"control panel ->network ->TCP/IP properties" and set up
an IP address close to the Toolkit IP address. I.e. as the
Toolkit is shipped with a default IP address of
169.254.111.111, the PC can be set up with IP address
169.254.111.150
YES
The PC and the Toolkit are set up with a correct IP
address and they are able to communicate with each
other
3
Can the Toolkit
communicate with a
DOS FTP program?
NO
The default user name and password is "ews". Check that
the user name and password are written in lowercase
YES
The user has access to the flash file system
4
Can the default web
pages be accessed
in a web browser?
NO
This is normally caused by the setup of the web browser.
In the "options" or "preferences" menu, check that the
web browser is configured for direct network connection
or local area network and NOT using a proxy server.
YES
No problems
