Connecting The Power Cords - HP AD510A - StorageWorks Modular Smart Array 1500 cs 2U Fibre Channel SAN Attach Controller Shelf Hard Drive Installation Manual

Connecting the power cords

To protect your system from power-failure-related down time, each MSA ships
standard with a redundant power supply. Depending how you connect the power
supplies to your power source, you can eliminate down time caused by
power-related failures.
When connecting the power cords, use the power cords shipped with the MSA.
After power is supplied to the MSA, the power supply automatically senses the
input voltage and the LED behind the power switch illuminates as solid amber.
