Setting the Power Mode
You can configure the power supply mode by using the power redundancy-mode command.
To display the current power supply configuration, use the show environment power command.
Note
Before you begin
For grid redundancy mode, the power supplies must be divided into two equal sets and installed as follows:
• Slots PS 1 to PS 4 must be connected to one grid (Grid A).
• Slots PS 5 to PS 8 must be connected to another grid (Grid B).
Step 1 Use the configure terminal command to enter the global configuration mode.
