AXIS 241QA/AXIS 241SA - Troubleshooting 63

Symptoms, Possible Causes and Remedial Actions

Problems setting the IP address

 

 

 

 

 

Using ARP/Ping - the IP address

Restart the server and try again. Ensure also the ping length is set to 408. (See the AXIS

another device

Run the Ping command (in a Command/DOS window, type ping <IP address of unit>

 

 

If you receive: Reply from <IP address>: 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

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

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

 

loaded

net.

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.
