Using Clear/Reset
Procedure
1. Using pointed objects, simultaneously press both the Reset and Clear buttons on the front of the switch.
2. Continue to press the Clear button while releasing the Reset button.
3. When the Self Test LED begins to flash, release the Clear button.
The switch then completes its self test and begins operating with the configuration restored to the factory
default settings.
Restoring a flash image
The switch can lose its operating system if either the primary or secondary flash image location is empty or
contains a corrupted OS file and an operator uses the erase flash command to erase a good OS image file
from the opposite flash location.
Recovering from an empty or corrupted flash state
Use the switch's console serial port to connect to a workstation or laptop computer that has the following:
• A terminal emulator program with Xmodem capability, such as the HyperTerminal program included in
Windows PC software.
• A copy of a good OS image file for the switch
NOTE: The following procedure requires the use of Xmodem and copies an OS image into primary
flash only.
This procedure assumes you are using HyperTerminal as your terminal emulator. If you use a
different terminal emulator, you may need to adapt this procedure to the operation of your particular
emulator.
1. Start the terminal emulator program.
Ensure that the terminal program is configured as follows:
• Baud rate: 9600
• No parity
• 8 Bits
• 1 stop bit
• No flow control
2. Use the Reset button to reset the switch.
The following prompt should then appear in the terminal emulator:
Enter h or ? for help.
