1300-watt and 1500-watt power supply supportability
The following table provides the 1300-watt and 1500-watt power supply
supportability to have better performance and power efficiency.
Note: When setting power redundancy policy through FPC after nodes are
powered on, it is possible that the current power bank is not sufficient to allow
N+1 or N+N configuration. Remove some or all of the nodes or lighten nodes
configuration before the redundancy policy can be applied.
To install a power supply, complete the following steps.
