I don't see the Firepower Chassis Manager IP in the FMC. Is there a way to locate it by connecting to the management IP of 4110?
Are you asking about when you connect to the management address of the FTD logical device running on the appliance?
You should be able to connect to fxos from the FTD clish prompt.
On FMC, you'd see the chassis hostname, if you've set correct hostname with domain, you'd be able ope up the URL once you click on it.
By connecting to mgmt of FTD, I doubt if you'd be able to get the chassis manager mgmt IP. You need to get console access to the device, login and run the command: "show fab a detail"
