Power for the storage system is provided through two power supplies, one per controller. The input voltage is auto-adjusting for 200-240 (-11%) VAC, 50-60 Hz power connections.
For best practice, establish power redundancy by routing each power supply to independent PDUs and then routing the PDUs to separate external power sources on different branch circuits. This arrangement enables the storage system to continue operating if AC power is lost to one power supply.
Note: Multiple outlets in a PDU or power strip do not constitute an independent electrical source.
