4.2.2 Factory Default Reset Behavior
When a factory default reset is detected, some parameters are reset to their default value:
•
Users (default user names and passwords).
•
All cryptographic material (keys, certificates, encryption settings).
•
All System Description information.
The unit will automatically load the previous configuration if no one connects to the unit using telnet within 20
seconds after the radio is available at the default IP address.
4.3 NETWORK TROUBLESHOOTING
Problem: The radio IP address is unknown.
•
Symptom: The radio is not able to be managed remotely.
•
Solution: The default radio IP address is 192.168.26.2. A Console Port cable (Harris PN 12069-3901-Axxx)
can be used to locally log into the radio to determine the IP address if the IP address has been changed. If
this is not an option, the radio can be power cycled in such a way that will reset the radio's IP address to the
default. Refer to
Paragraph 4.2.1 for the factory reset procedure.
Problem: The radio IP address is the same as another device on the local network.
•
Symptom: The radio's management interfaces (HTTP, HTTPS, Telnet, SSH, SNMP) are not accessible to a
computer on the same network.
•
Solution: Change the radio IP address to be unique.
Problem: The radio IP address is the same as another device on the other end of the radio link.
•
Symptom: The radio's management interfaces are not accessible to a computer on the same network
segment, but only when the local radio has an active RF link to the remote radio.
•
Solution: Change the radio IP address to be unique.
Problem: The radio has Management VLAN tagging enabled and set to a VLAN ID that is not the same as other
computers on the network.
•
Symptom: The radio's management interfaces are not available.
•
Solution: The network administrator needs to enable the VLAN ID on switch ports for computers that need
to access the radio's management interfaces.
Problem: The radio and computer are configured for different subnets.
•
Symptom: The radio's management interfaces are not accessible to a computer on the same network
segment.
•
Solution: Change the IP addresses and subnet masks so both devices are on the same subnet. If this is not
an option, the network is not configured properly.
