Appendix A - Troubleshooting
This appendix provides useful information to help you to resolve any difficulty you might
have with your AXIS 2420. Symptoms, possible causes and remedial actions are provided
in a quick reference table.
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 2420 on the network.
Having disconnected your AXIS 2420, follow the instructions below in association with
Symptoms, Possible Causes and Remedial Actions, on page 48, 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 2420.
3. If you recieve the reply
destination host unreachable,
then the AXIS 2420 is not
accessible on your subnet. You must obtain a new IP address and reinstall the unit.
4. If this does not solve the problem, disconnect the AXIS 2420 from the network and run
the PING command again. See the table below for an interpretation of the results.

performed correctly. In this case, reinstall the unit. Also check all cabling.
