        The fan hasn't failed, it's a monitoring issue.  Unfortunately,
the fix is a new power supply.  We've swapped a large number of these
of late. 
        Incidentally, make sure you swap them inside a maintenance window
because sometimes when you're doing it the power supply will freak, throw
a high temperature alarm, and the router will shut itself off as a result.
