Let's assume this is a modern variant of VMware, ESXi 5.x, perhaps? Standard VMware ESX is defunct.
- You have physical access to the server. (This is good!)
- The management IP address of the server is incorrect. (How did that happen?)
- You say that the console is disabled. (Not possible unless you took explicit actions to configure Total Lockdown Mode through vCenter)
Your solution, assuming ESXi and basic lockdown mode, is to login via the console and change your management network settings.
If Total Lockdown mode is enabled and the DCUI is disabled, you can only manage this host from vCenter. If access to vCenter is lost, you will need to reinstall ESXi.
If the latter is the case, please tell us how you ended up in this situation. It may help you (and others) understand how to avoid this in the future.
