Where can a system administrator check and change power supply redundancy options on a Dell EMC PowerEdge server?

In a Dell EMC PowerEdge server, a system administrator can efficiently check and modify power supply redundancy options using the iDRAC (Integrated Dell Remote Access Controller) GUI. iDRAC provides extensive remote management capabilities, allowing administrators to access hardware status and settings, including power configuration features.

Through the iDRAC GUI, one can easily navigate to the power management settings to visualize the current power supply status, monitor redundancy settings, and make adjustments as necessary. This user-friendly interface is particularly beneficial for managing power supplies without needing physical access to the server or booting into other utilities.

Other options, while relevant to server management, do not provide the specific functionality for power supply redundancy control. The Dell Power Manager interface primarily focuses on overall power consumption and performance rather than direct supply options management. The UEFI BIOS offers fundamental hardware configuration but may not provide a straightforward way to monitor and change redundancy settings specifically. The PXE web interface is primarily utilized for booting and deploying images over the network and lacks direct access to power management features.
