SB replacement can lead to to a serial number of '00000000' which will break ASR if the SBs are not reprogrammed after replacement. In order to reprogram the serial number you will first need access into 'Service Mode' and this requires a long password which is obtained from our TSC backline. This 'Escalation' password is needed to reprogram the serial number of the system board.
An Escalation password (similar to service password) is valid for 48 hours, and is provided by our TSC backline. The following information is needed in order for the TSC backline to generate your temporary password granting access to Service Mode in order to reprogram the serial number.
You will initially need to provide the following information:
..ILOM Version? (see "version" output)
..Serial Number? (-> show /SYS [ or /CH ] product_serial_number )
..When you will be onsite? (How soon do you need this escalation password?)

Please refer to document 'x86_serial_number_10_min_1.1.2.pdf'
for additional scope on reprogramming the serial number of the system board.
