Reset Button

The Reset button, located on the front panel of the switch, allows you to manually
recycle power and reset the switch. Pressing the Reset button initiates a warm
boot of the system and generates power-on self test (POST) and diagnostics. The
button is recessed into the unit to prevent accidental resets. Use the tip of a pen or
pencil to reset the switch.
