The AXIS 2420 cannot be
accessed from a Web
browser.

The IP address is already
being used by another
device.

1. Disconnect your AXIS 2420 from the network.

2. Run the PING utility (as described in PINGing Your IP Address, on

page 47) and follow the appropriate recommendations.

Note: The assigned IP number can be assumed as being available
for use if PING returns “request timed out” - in which case you
should set the IP address again, power on the AXIS 2420 and then
try accessing the unit again.

The IP address is located on a
different subnet.

Run the PING utility (as described in PINGing Your IP Address, on
page 47). If the utility returns

no response

or similar, then this

diagnosis is probably correct.
In Windows, check that the IP address for your AXIS 2420 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 2420 is on a different subnet than your workstation
you will not be able to set the IP address from this workstation.
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.
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 2420, using ARP.
The AXIS IP Installer is a good alternative to ARP.

The IP address has changed.

Check that there is no DHCP or BOOTP server running on your
network.

Possible problem with your
proxy server.

Try disabling the proxy default in your browser.
