2.8.1 Redundant Configuration of Power Supply Units


2.8.1 Redundant Configuration of Power Supply Units
The SPARC M12-2S has power supply units in a 2+2 redundant configuration as standard. If failures occur in two power supply units, the system can still continue to operate with the remaining two power supply units. However, if a failure occurs in the external power supply, the system stops.
Figure 2-12 and Figure 2-13 show power supply systems with redundant power supply connections.

When connecting the power cords to the same power supply, make sure to connect each power cord to the circuit breaker in a one-to-one manner.

*2 In expansion rack 2
Note - The system consumes no power when there is no device connected to the PDU outlets. For the wiring of power cords within the expansion rack, see Figure 2-23.
