The internal power supplies are inserted in the back slots. These slots are labeled PS1 and PS2 on the 5406zl 
and PS1 through PS4 on the 5412zl. A power supply is hot-swappable provided at least one other power 
supply is operational. If the 5412zl has only two power supplies and one of them fails, then only the upper six 
slots (slots A through F) will receive power.
