Managing Power Supplies

To manage power supply power attributes, perform the following steps.
Step 1 From the Fabric Manager menu tree, choose Switches > Modules and then click the Power Supplies
tab, or from the Device Manager, choose Physical > Power Supplies. The Information pane from the
Fabric Manager displays power supply power attributes for multiple switches. The dialog box from the
Device Manager displays power supply power attributes for a single switch.
Configure the power attributes for the power supply.

You decide to change the switch to redundant mode. Then the current capacity decreases to
2500Watts and the configuration is rejected.
Reason: 2500Watts is less than the system usage (3000Watts).
