Be careful with wall-warts.  If it doesn't explicitly say that it will 
work at 240V, or it's not clear that it will, don't try to plug into a 
higher voltage outlet. Many wall-warts are still floating around that 
don't work at >120 VAC and will instantly release their magic smoke...

The other thing is if you use PDUs that have IEC C13 connectors for 120V 
devices, you might need IEC-C14 <-> NEMA 5-15R adapter cords, an 
appropriate PDU with NEMA 5-15R or 5-15/20R recaptacles, or some NEMA 
5-15/20R convenience outlets to provide a place to plug in those wall-warts.
