Symptoms Possible causes Remedial actions
The AXIS 2400+/2401+ 
cannot be accessed from a 
browser.
The IP address is already 
being used by another 
device.
Run the PING utility (as described above) and follow the 
appropriate recommendations. 
The IP address is located on a 
different subnet.
Run the PING utility (as described in PINGing Your IP Address, on 
page 38). If you get “no response” or similar, the diagnosis is 
probably correct.
In Windows, check that the IP address for your AXIS 2400+/2401+ 
is on the same subnet as your workstation. Exactly how this is done 
varies from one version of Windows to another. See Windows’ help 
for more information.
If your AXIS 2400+/2401+ and your workstation are on different 
subnets, you will not be able to set the IP address. Contact your 
network administrator.
In Windows 95, the ARP 
table was empty when you 
tried to set the IP address. 
In Windows 95, the ARP command cannot be used if you have an 
empty ARP table. If the table is empty, re-install the product 
ensuring that the IP address for your own PC is also used. 
Type 
arp -a to view the ARP table. If it is empty, you must ping 
an existing unit on your network before you can download the IP 
address to the AXIS 2400+/2401+, using ARP. 
Note: The AXIS IP Installer is an easy-to-use alternative for 
installing the unit.
The IP address has changed. Check that there is no DHCP server running on the network and 
disable BOOTP in the video server.
Note: The AXIS IP Installer will not work with DHCP.
Other networking problems. Test the network cable by connecting it to some other network 
device and then PINGing that device from your workstation.
Test the unit’s network interface by connecting a local computer to 
the unit, using a standard Crossover (hub-to-hub) Cable. 
If the above actions do not resolve the problem, the AXIS 
2400+/2401+ may be faulty. In this case, try to localize the 
problem by connecting the unit to the serial port of a local 
computer, using the supplied Null Modem Cable and report your 
findings to your local distributor.
A programming script is 
locking the unit.
Restore the unit to the factory default settings. 
The Power indicator is not 
constantly lit.
Faulty power supply. Verify that you are using an Axis PS-D power supply.
The Network indicator 
displays red.
Faulty cabling.  See Other networking problems, above.
The Status indicator is 
flashing red rapidly. 
Hardware failure. Contact your Axis dealer.
