SECTION 6 TROUBLESHOOTING
Common Problems
Login windows does not appear
After typing the IP address of CWM in the URL window, the login window should
appear.
If it does not, it could be due to incorrect IP address or the index.html file is
missing or wrongly programmed, or the network cable may have been
connected after the CWM was powered up. Always connect the network cable to
the CWM RJ45 socket before connecting power to the CWM. If the CWM is
powered on before the Network is connected, its network drivers will not be
loaded and the network connection will NOT work.
Login window is cleared after entering code
If the Login window appears (like above picture), and the correct code is
entered and transmitted, but the Login Window is cleared, without a “correct
code” or “Invalid Code” message, Comfort or the CWM may not be connected
correctly. The causes of this could be CWM UCM ID (SW7) not set to the correct
ID, or Comfort Location 1672 (Modules and Settings Screen in Comfigurator)
not set to the correct number of UCMs, or the CWM is not switched on, or the
network cable may have been connected after the CWM was powered up.
Take note that over the Internet there could be up to 10 to 50 seconds delay
(depending on Internet traffic) between the time the login code is entered and
the “OK” message is received.
Web page does not appear
If the Login window does appear, and the correct code has been entered and
acknowledged by CWM, but the expected background image does not appear,
the most likely cause is that one or more of the image files specified in the
index.htm file is missing, or the file name does not match the name specified in
the file. Check all the image file names in the index.htm file against the actual
files in the specified image folder.
Take note that over the Internet there could be 10 to 50 seconds delay before
the CWM home page appears, depending on the speed of the connection,
Internet traffic and the size of the images.
