Change WWNN? option

Edit online

The Change WWNN? option displays the last five hexadecimal digits of the WWNN that is being used by the node. Only the last 5 digits of a WWNN vary on a node. The first 11 digits are always 50050768010.

To edit the WWNN, complete the following steps:

  4. Edit the highlighted number to match the number that is required. Use the up and down buttons to increase or decrease the numbers. The numbers wrap F to 0 or 0 to F. Use the left and right buttons to move between the numbers.
  5. When the highlighted value matches the required number, press and release the select button to activate the change. The Node WWNN panel displays and the second line show the last 5 characters of the changed WWNN.
