1. Attach a terminal or PC with terminal emulation to the console port of the switch. Use the following terminal settings:

   9600 baud rate
   No parity
   8 data bits
   No stop bit

2. Unplug the power cable.
3. Hold down the mode button while reconnecting the power cord to the switch. You can release the mode button a second or two after the LED above port 1x is no longer illuminated.

   The following instructions appear:

   The system has been interrupted prior to initializing the flash file system. 
   The following commands will initialize the flash file system, and finish loading
