Appendix A - Troubleshooting
Remedial actions
Verify that you are using an AXIS PS-D power supply.
1. To verify that the cables are functional, PING the address
of a known unit on your network.
2. If the cabling is OK and your network is reachable, you
should receive the reply similar to this:
...bytes = 32 time = 2 ms,
Contact your Axis dealer.
Check the Internet firewall with your system manager.
Check if you need to configure the default router settings.
Configure the AXIS 2120 to upload your video images to an
FTP server or an ISP.
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.
Check the modem power supply and modem cable connec-
tions, and ensure that the modem is configured appropri-
ately.
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 stan-
dard 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.
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 expo-
sure to direct sunlight or halogen light is not covered by the
product warranty.
