What to do if there is an AC input failure in my 3Com 4210G?

If there's an AC input failure with your 3Com Switch, check if the AC power cord is properly connected to the switch and the AC power socket. Also, verify the external AC power supply system is functioning correctly and that the switch's operating temperature is within the normal range with good ventilation.
