The HP StorageWorks Core Switch 2/64 uses up to four power supplies with a
minimum of two required to power a completely loaded chassis. The left power
connector provides power to the power supplies in slots #1 and #3 (color-coded
blue), and the right power connector provides power to the power supplies in slots
#2 and #4 (color-coded yellow).
The HP StorageWorks Core Switch 2/64 can continue operating while a power
supply is replaced if at least one power supply continues operating for every four
16-port cards installed. HP recommends a minimum of two power supplies.
