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.
LEDs
Table 3-1 lists the meaning and actions of the LEDs, Table 3-2 lists the RJ-45 
LED meanings, and Table 3-3 lists the meaning of the FX LEDs.
