Can't connect to Host subsystem console

Hey guys,



I've just replaced one of my 3400s and it's all working fine except for the serial connection.



I can see the unit boot, but when it's finished booting I get dropped to a '>' prompt. I can't seem to do anything from here except bring up the [hostconsh] Command Menu:.



Has anyone come across this before?

    Hi smeegs,



    I've seen a lot of things, but this would be a first. If you can get to the GUI and/or SSH to the unit then you aren't stuck in single user mode or busybox. I would make sure that this replacement unit is running the same version of BIG-IP as its partner and that the configs have been synced. If all that is good, I'd SSH to the box and do a full_box_reboot on it from the command line. If that doesn't resolve the issue, I'd open another support case.
