(Optional) Displays the status of the internal power supplies for each device in the stack or for the specified device. The range is 1 to 8, depending on the device member numbers in the stack. The device keywords are available only on stacking-capable devices. |
This example shows a sample output of the show power detail command when a power supply with serial number starting with QCS is installed on the C9500X-60L4D switch.
