I have a 3110x stack in a H Bladecenter Chassis and 2 of the modules can not enable their external ports. When attempting to perform a no shut on the interface I receive the error
shutdown not allowed on this interface
When in AMM and trying to disable protected mode so I CAN enable the external port I get this error
Protected mode on I/O module 7 has to be disabled on this I/O module's native management interface first.
The dropdown menu for External Ports to enable/disable is Greyed out (can't be selected).

Without knowing more about your situation, I'd say, break the stack, enable the external ports on all switches, then rebuild the stack.
This will certainly be disruptive. Be sure to limit upstream connectivity (to prevent loops) and save a copy of the configuration prior.
