How to reconfigure ip-block on Firepower Management Chassis

[CarsonDavis56998]

I am in the process of setting up a new Firepower 9300. However, I accidentally misconfigured the IP block settings while trying to bring up the chassis manager, and now I cannot connect via HTTPS or SSH. How can I reconfigure the IP block to allow HTTPS access to the chassis manager?

Currently I am connected via Console/serial connection

You have two options:

1. Serial Console
2. Directly attach a computer to the mgmt interface > Configure a static IP on the computer that is in the same subnet as the mgmt interface
