Reset Button

The RESET button is recessed within a hole on the front panel. Use a straightened 
paper clip or similar object to press the RESET button. The RESET button allows 
technicians to reset the switch, as follows: 

„

Press RESET—The switch resets and reloads the configuration files. 

„

Press and hold RESET for 5 seconds—The switch resets and configures all 
settings to factory defaults. 

Fans

Six internal fans cool the switch unit. If an individual fan fails, the other fans 
continue to run, and the switch unit continues to operate normally. Fans are not 
customer replaceable.
