Part No. 18627 R1.1
Possible causes
The IP address is already used
by another device.
The IP address is located on a
different subnet.
In Windows 95, the ARP
table was empty when you
tried to set the IP address.
Proxy server.
Other networking problems.
Faulty power supply.
Hardware failure.
Firewall protection.
Default routers required.
The IP settings in the 2490
are wrong.
The TCP port number is
wrong.
The 2490 is not in Generic
TCP/IP mode.
Someone else is already
using the port and has
connected to the Axis 2490.
You have enabled "Allowed
IP addresses" but your IP
address is not allowed.
Remedial actions
Disconnect your AXIS 2490 from the network, run the PING utility and
follow the appropriate recommendations.
Run the PING utility. If the utility returns "no response" or similar, in
Windows 95/98 or Windows NT/2000, you should then check that the
IP address for your AXIS 2490 is on the same subnet as your
workstation.
If these subnets are different, the IP address cannot be set from the
workstation. Please contact your network administrator.
If the table is empty, re-install the product, ensuring that the IP
address for your own PC is also used. Type
table.
Try disabling the proxy default in your browser.
Try replacing your network cable.
Test the network interface of the product by connecting a local
computer to the unit, using a standard Crossover (hub-to-hub) Cable.
If the above actions don't solve the problem, the AXIS 2490 may be
faulty. In this case, try to localize the problem by connecting the AXIS
2490 to the serial port of a local computer, using a Null Modem Cable
and report your findings to your local distributor.
Verify that you are using an AXIS PS-B power supply.
Contact your Axis dealer.
Check the Internet firewall with your system administrator.
Check if you need to configure the default router settings.
Check the IP number, router and netmask settings.
Make sure you use the same port number the 2490 is configured for.
Check the settings in the 2490.
Select "View Log FIle" in the Server settings to see if anyone else has
connected. You may want to configure "Allowed IP addresses" and
restart the unit.
Check the settings in the 2490.
