You can adjust the amount of Available Power and Reserve Power that is partitioned from the chassis Total Power by increasing or decreasing the Reserve Power Supply Unit (PSU) Count. Before you adjust power partitioning, consider the following power management principles:
If you decrease the Reserve PSU Count, power is transferred to chassis Available Power. Available Power increases and the Reserve Power decreases.
If you increase the Reserve PSU Count, Power is transferred to Reserve Power. Available Power decreases and the Reserve Power increases.
You can increase or decrease the Reserve PSU Count in increments of 1 power supply module. The Reserve PSU Count cannot exceed one unit less than the total number of power supply modules.
