Displays the inline power status of all interfaces. For verification and the command output display, use the show switch interface inline-status command.

How do I check my power supply voltage?

Switch your multimeter to the range that is appropriate for reading the voltage from your power supply. If your power supply’s voltage is 125 volts, switch your multimeter to read a range of 100-200 volts. Some multimeters may not offer a range, so you may need to choose the approximate voltage on a dial.
