The Network indicator dis-
plays red.
Faulty cabling. 1. To verify that the cable is functional, connect the cable to a
known functioning device on the network and PING it from your
workstation.
2. If the cabling is OK and your network is reachable, you should
receive a reply similar to this:
Reply from <IP address>: bytes = 32; time

The Active and Network indi-
cators are flashing every 0.5
seconds
Hardware failure. Contact your Axis dealer.
Your AXIS 2120 works
locally, but not externally.
Firewall protection Check the Internet firewall with your system manager.
Default routers required Check if you need to configure the default router settings.
Slow image updating The Internet site is too
heavily loaded
Configure the AXIS 2120 to upload your video images to an FTP
server or an ISP.
No image using Refresh
and/or slow updating of
images.
Requests for images of vary-
ing size and resolution place
a greater demand on the
available file space within
the AXIS 2120.
Ensure that all the clients accessing the images are using the same
image resolution and compression. For large numbers of clients,
configure the AXIS 2120 to upload your images to an FTP server or
an ISP.
Cannot access the con-
nected modem.
Modem not properly
connected.
Check the modem power supply and modem cable connections, and
ensure that the modem is configured appropriately.
Incorrect initstring. Send command AT&F1 to return your modem to factory default,
and then try accessing the modem again. If this does not resolve
the problem, it is likely that your modem uses an initialization
string that is different from the standard ATZ command used by the
AXIS 2120. In this case, refer to the user information supplied with
your modem to find the unique initstring command for your unit.
A series of broad vertical
white lines appear across the
image.
The CCD sensor becomes
overloaded when the light is
too bright. This can happen
e.g. with sunlight reflexes.
Direct exposure to extreme sunlight or halogen light may cause
serious damage to the CCD sensor. Reposition your AXIS 2120 in a
more shaded location immediately.
Note: damage caused to the AXIS 2120 through over exposure to
direct sunlight or halogen light is not covered by the product war-
ranty.
