Connecting The Power Cords - HP StorageWorks Modular Smart Array 1500 cs Installation Manual

Connecting the power cords

To protect your system from power-failure-related downtime, each MSA1500 cs
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
MSA1500 cs. After power is supplied to the MSA1500 cs, the power supply
automatically senses the input voltage and the LED behind the power switch
illuminates as solid amber.
