VGMC Password Reset

Procedure to reset the VGMC login and password to 'itgadmin', you can then use the setLeader command to set the IP Address:

  1. Connect a terminal to the Maintenance port, either directly (female DIN-8, labeled Maint), or via the I/O panel (DB-9 male). The terminal communication parameters must be as follows:
    9600 baud, 8 data bits, no parity, 1 stop bit
  2. Press the Enter key on the keyboard.
    The IPL> prompt is displayed.
  3. Reboot the card by pressing the RESET button on the faceplate of the card with a pointed object, such as a ball-point pen.
  4. Start up messages are displayed on the terminal. Type jkl on the terminal keyboard when the prompt is displayed.
    Note: jkl runs from BIOS or boot ROM which is printed early in the bootup process. There is only a six second window at the prompt to enter jkl. If the prompt is missed, restart the card and repeat the above step.
  5. Once the card has booted from BIOS or boot ROM, a CLI prompt (such as the BIOS>) appears.
    Enter the following command: shellPasswordNvramClear at the CLI prompt.
  6. Type reboot at the prompt to reboot the card.
