 +===== Switch reset - data gathering algorithm =====
 +
 +From IBM GI1956:-
 +
 +<​code>​
 +Important: Follow this procedure carefully. ​ Failure to do so can cause permanent damage to switch hardware.
 +
 +1. Set up the switch debugger:
 +
 +    a. Attach a PC to the serial port of the switch that has reset.
 +    b. Set up the terminal emulator to log the screen to a file.
 +    c. From the switch console, ​ enter the switch debugger by  pressing Ctrl-t. ​ Enter the switch ​  ​password at the prompt if  a password ​ is used on the switch. ​ You must  press Ctrl-t ​ from a screen ​ other than the sign-on screen.
 +    d. At the "​eps>"​ prompt, ​ enter one of the following commands:
 +            perf 40  (if you are using 8272 code version 2.3.1 or earlier)
 +            extmsgs on   (if you are using 8272 code version 2.3.2 or higher)
 +
 +        Note: Either of these  commands will enable extended ​ messaging. ​ The difference between the two is that  "​extmsgs on" enables extended messaging indefinitely; ​  when you are finished, enter   ​extmsgs off  to turn it off.
 +
 +       
 +2. Allow the emulator to continue to log to a file so that all messages are captured. ​ Allow the eps> ​ debugger screen ​ to remain on the console ​ the  until the switch resets.
 +
 +3.  If you need to return to the main menu:
 +
 +    a. Type cons  to return ​ to the main menu.
 +    b. Use  the menus as needed.
 +    c. Press Ctrl-t to return ​ to the debugger screen, remaining there  until the switch resets.
 +
 + 
 +4.  After the switch resets, stop the screen capture on the emulator. ​ Send captured data to IBM Support personnel.
 +
 +Note: If you are  using code version 2.3.2 or higher, go  to the debugger screen ​ after the box resets and type extmsgs off at the eps> ​ prompt to set extended messaging off.
