Verifying The Master Key Code - IBM 3274 User Manual

14. Press the ENTER key. When the ENTER key is pressed,
the verification value is stored on the Encrypt/Decrypt
diskette, and the top two rows of the display screen change
to:
VP
XXXXXXXXXXXXXXXX
99
The keyboard is now disabled and cannot be reset until an
IML operation is performed. To continue your normal
operation, turn the 3274 Encrypt/Decrypt key switch
counterclockwise to the vertical position, remove the
security key from the key switch, replace the
Encrypt/Decrypt diskette with an operational diskette, and
press the IML pushbutton. After the IML operation is
completed, notify all terminal operators that the 3274 is
again operational.
Note:
Operator information area symbols and codes that may
be displayed during the execution of this procedure are
explained in the 3270 Information Display System:
Reference Summary, GX20-1B7B-5 or higher, and in the
applicable display station problem determination guide.

Verifying the Master Key Code
This procedure will indicate whether the master key
verification value stored on the associated Encrypt/Decrypt
diskette matches the verification value of the master key code
currently stored in the 3274. If the values match, a 99 will be
displayed; if the values do not match, a 44 will be displayed.
To execute this procedure, first contact the appropriate person
in your organization to obtain the associated Encrypt/Decrypt
diskette.
