AXIS 241QA/AXIS 241SA - Troubleshooting

Symptoms, Possible Causes and Remedial Actions

Problems setting the IP address

Using ARP/Ping

- the IP address

must be set within two minutes
after power has been applied to
the video server

Restart the server and try again. Ensure also the ping length is set to 408. (See the AXIS
241QA/AXIS 241SA Installation Guide)

The video server is located on a
different subnet.

If the IP address intended for the AXIS 241QA/AXIS 241SA and the IP address of your computer
are located on different subnets, you will not be able to set the IP address. Contact your net-
work administrator for an IP address on the same subnet as the computer you are performing
the installation from.

The IP address is being used by
another device

Disconnect power from the AXIS 241QA/AXIS 241SA.
Run the Ping command (in a Command/DOS window, type

ping <IP address of unit>

If you receive:

Reply from : bytes = 32; time = 10 ms..... - this means that the IP

address may already be in use by another device on your network. You must obtain a new IP
address and reinstall the unit.

If you receive:

Request timed out - this means that the IP address is available for use with your

video server. In this case, check all cabling and reinstall the unit.

The AXIS 241QA/AXIS 241SA cannot be accessed from a web browser

Cannot log in

If the AXIS 241QA/AXIS 241SA has been configured to use HTTPS, check that the protocol in
the URL used to access the unit is correct. You may need to type this in manually (i.e. http or
https) in the browser’s address field.

The IP address has been changed
by DHCP

1) Move the AXIS 241QA/AXIS 241SA to an isolated network or to one with no DHCP or BOOTP
server. Set the IP address again, using the ARP Ping command.
2) Access the unit and disable BOOTP and DHCP in the TCP/IP settings. Return the unit to the
main network. The unit now has a fixed IP address that will not change.
3) As an alternative to 2), if dynamic IP address via DHCP or BOOTP is required, select the
required service and then configure IP address change notification from the network settings.
Return the unit to the main network. The unit will now have a dynamic IP address, but will
notify you if the address changes.

Other networking problems

Test the network cable by connecting it to another network device, then Ping that device from
your workstation. See instructions above.

Cannot send notifications, uploads, alarms, etc, to a destination outside the local network

Firewall protection

The video server can be configured to use a SOCKS server to reach networks on the other side
of a firewall/proxy server

Your AXIS 241QA/AXIS 241SA is accessible locally, but not externally

Firewall protection

Check the Internet firewall with your system administrator.

Default routers required

Check if you need to configure the default router settings.

The Internet site is too heavily
loaded

Use a script on your web server to relay images from the AXIS 241QA/AXIS 241SA to the Inter-
net.

The Power indicator is not constantly lit

Faulty power supply

Verify that you are using the correct power adapter.

The Status indicator is flashing red and the server is inaccessible

A firmware upgrade has been
interrupted or the firmware has
been damaged in some other
way.

A rescue firmware is running in the product. First, set the IP address using AXIS IP utility or ARP
and Ping, (See the AXIS 241QA/AXIS 241SA Installation Guide). Then, using a web browser,
access the unit and download the latest firmware to the product, see Upgrading the firmware,
on page 61
