AXIS 247S - Troubleshooting

Symptoms, Possible Causes and Remedial ActionsI

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 AXIS 247S Video

Server Installation Guide)

The Video Server is located on a

different subnet.

If the IP address intended for the Video Server and the IP address of your computer are located

on different subnets, you will not be able to set the IP address. Contact your network adminis

trator 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 Video Server.

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 Video Server cannot be accessed from a Web browser

Cannot log in If the Video Server 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 Video Server 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 Video Server 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 Video Server to the Internet.

The Power indicator is not constantly lit

Problem with PoE Check the PoE switch

Faulty power supply Verify that you are using an AXIS PS-K power supply.

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 AXIS 247S Video Server Installation Guide. Then, using a browser, access the unit

and download the latest firmware to the product, see

Upgrading the Firmware, on page 33.

No images displayed in the Web interface

Problem with AMC

(Internet Explorer only)

To enable the updating of images in Microsoft Internet Explorer, set your Web browser to allow

ActiveX controls. Also, make sure that AXIS Media Control (AMC) component is installed on

your workstation.

Installation of additional ActiveX

component restricted or prohib

ited

Configure your Video Server to use a Java applet for updating the images under

Live View Config > Layout > Default Viewer for Internet Explorer. See the online help for more

information.

Video Image Problems

Image too dark or too light. Check that the termination dip switch for the video source is set to the correct position. See

also the online help on Video Source Settings

Black borders around the video

image

Adjust the X and/or Y offset, in the Video Source Settings. See the online help for information.

Problems uploading own files There is only limited space available for the upload of your own files. Try deleting one or more

existing files, to free up space

Missing images in uploads This can occur when trying to use a larger image buffer than is actually available. Try lowering

the frame rate or the upload period.

Slow image update Configuring e.g. pre-buffers, motion detection, high resolution images, high frame rates, etc.,

will reduce the performance of the Video Server.

Slow performance Slow performance may be caused by e.g. heavy network traffic, multiple users accessing the

unit, low performance clients, use of features such as Motion Detection, Event handling.
