I am looking at two X440-48Poe switches, both working with 15.7.1.4 XOS. One switch supplies POE and the other does not. On the working switch SHOW INLINE-POWER returns the firmware status and power wattage information. On the switch that does not supply POE (otherwise working) the command returns no firmware or power wattage information, its just missing. Is this a bad power supply? I tried UNCONFIGURE SWITCH, didn't help.
