Troubleshooting the Appliance Preconfiguration
Troubleshooting the Appliance Preconfiguration
If your appliance is correctly preconfigured for target deployment, you can install and deploy the
appliance without further configuration.
If you have difficulty logging into the appliance, the preconfiguration may have an error. Try the
following troubleshooting procedures:
•
Confirm that all power cables and communication cables are connected properly to the appliance.
•
Confirm that you have the current password for your appliance. The initial setup at the staging
location prompts you to change your password. See the configuration information provided by the
staging location for the new password.
•
Confirm that the network settings are correct. See
Initial Setup Page: Firepower Devices, page 5-5
.
•
Confirm that the correct communication ports are functioning properly. See the documentation for
your firewall for information on managing firewall ports. See
Communication Ports Requirements,
for required open ports.
•
If you use a Network Address Translation (NAT) appliance in your deployment, confirm that NAT
is configured correctly. See Working in NAT Environments in the
Firepower Management Center
Configuration Guide
.
If you continue to experience difficulty, contact your IT department.
