Replacements: "fired upon"

[ComradeP]

Does the "must not be fired upon" rule for determining if a unit can receive replacements require that a unit takes losses, or will No Effect results also prevent a unit from absorbing replacements?

Will combat situations where a unit in the hex is fired upon with the fire hitting the entire stack (such as, for example, with defensive artillery fire), but not the unit you want to take replacements (as in: it doesn't suffer any losses) also prevent that unit from taking replacements?
