AXIS 2120 User’s Manual Troubleshooting

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 2120 on the network.
Follow the instructions below in association with Symptoms, Possible Causes and Remedial
Actions, on page 56, and run the PING utility 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 2120.
3. If you recieve the reply
destination host unreachable, then the AXIS 2120 is not
accessible on your subnet. You must obtain a new IP address and reinstall the unit.
If this does not solve the problem, disconnect
the AXIS 2120 from the network and run the
PING command again. See the table below for an interpretation of the results.

This IP address is not used and is available for use with your AXIS 2120. If
you set the IP address previously, the installation might not have been
performed correctly. In this case, reinstall the unit. Also check all cabling.
