• If you install two power supply units in the system, you can switch the
working behavior of the two PSUs between 1+1 jumper mode and 2+0
jumper mode.
1+1 jumper mode: If the total power consumption of the system is less
than 1400W, the system can be booted using one PSU and the PSU hot-
swap feature is supported. If the total power consumption of the system
exceeds 1400W, the maximum output power of the PSUs can reach to
2800W with PSU hot-swap feature disabled, and the system shuts down if
any of the PSUs is removed.
2+0 jumper mode: The system can be booted only when two PSUs are
installed. The maximum output power of the PSUs can reach to 2800W with
PSU hot-swap feature disabled, and the system shuts down if any of the
PSUs is removed.
• The output power varies with different input voltages. Refer to the table
