Appendix C - Troubleshooting
This appendix provides useful information to help you to resolve difficulties with your
AXIS 2460. Symptoms, possible causes and remedial actions are provided in a quick
reference table.
Checking the Firmware
One of your first actions when attempting to solve a problem should be to check the
firmware version currently installed. An updated version may contain a correction that
fixes your particular problem. For more information, please see Updating the Firmware, on
page 61.
Pinging Your IP Address
By sending a packet to the specified address and waiting for a reply, the Ping utility can
determine whether a specific IP address is accessible. It also provides a particularly useful
method for confirming addressing conflicts with your AXIS 2460 on the network.
Follow the instructions below in association with Symptoms, Possible Causes and Remedial
Actions, on page 56, and run PING to troubleshoot TCP/IP problems on your network:
1. Start a Command window.
2. Type
ping x.x.x.x
, where
x.x.x.x
is the IP address of the AXIS 2460.
3. If you recieve the reply
destination host unreachable,
then the AXIS 2460 is not
accessible on your subnet. You must obtain a new IP address and reinstall the unit.
Please see Installing the AXIS 2460 Network DVR, on page 12.
4. If this does not solve the problem, disconnect the AXIS 2460 from the network and run
the PING command again. See the table below for an interpretation of the results.
