Best practices overview for AC power connections
To assure fault tolerant power, external AC power must be supplied from independent,
customer-supplied, power distribution units (PDUs) as shown in Figure 1 on page 14.
For systems operating from three phase AC power, two independent and isolated AC
power sources are recommended for the two individual power zones in each rack of
the system. This provides for the highest level of redundancy and system availability.
If independent AC power is not available, there is a higher risk of data unavailability
should a power failure occur, including individual phase loss occurring in both power
zones.
Before connecting external AC power to storage bays, verify that the bays have been
placed in their final position as explained in the installation guide.
