Product serial number
The node contains a product serial number that is written to the system board hardware. The product serial number is also printed on the serial number label that is on the front panel.
This number is used for warranty and service entitlement checking and is included in the data that is sent with error reports.
Remember: Do not change this number during the life of the product. If the system board
is replaced, you must follow the system board replacement instructions carefully and rewrite the
serial number on the system board.
