Symptoms, Possible Causes and Remedial Actions
Problems setting the IP address
When using ARP/Ping
Try the installation again. The IP address must be set within two minutes after power has been
applied to the product. Ensure the Ping length is set to 408. For instructions, see .
The product is located on a
different subnet
If the IP address intended for the product and the IP address of the computer used to access the
product are located on different subnets, you will not be able to set the IP address. Contact your
network administrator to obtain an IP address.
The IP address is being used
by another device
Disconnect the Axis product from the network. Run the Ping command (in a Command/DOS
window, type
ping
and the IP address of the product):
• If you receive:
Reply from <IP address>:
bytes=32; time=10...
this means that the IP address may already be in use by another device on the network.
Obtain a new IP address from the network administrator and reinstall the product.
• If you receive:
Request timed out
, this means that the IP address is available
for use with the Axis product. Check all cabling and reinstall the product.
Possible IP address conflict
with another device on the
same subnet.
The static IP address in the Axis product is used before the DHCP server sets a dynamic address.
This means that if the same default static IP address is also used by another device, there may
be problems accessing the product.
The product cannot be accessed from a browser
Cannot log in
When HTTPS is enabled, ensure that the correct protocol (HTTP or HTTPS) is used when attempting
to log in. You may need to manually type
http
or
https
in the browser’s address field.
If the password for the user root is lost, the product must be reset to the factory default settings.
See
Reset to Factory Default Settings, on page 52
