Replacement during shelf power-off with a spare MF106
If a MF106 is replaced with a spare MF106 which has not been used before, the Shelf FRU
Validation tool will recognize the default shelf FRU information and update it with the system's
shelf FRU information after next power-up. The shelf FRU information remains valid.
Replacement during shelf power-off with a already used MF106
If a MF106 is replaced with an already used MF106, the shelf FRU information is upadated
correctly on the used MF106. The backplane stores the primary copies of the Shelf FRU data,
so a used MF106 can be inserted into a powered off Shelf.
If the shelf geographical address cannot be determined, HPI will not start.
If the Shelf Geographical Address cannot be determined at power-up, and to get a valid shelf
FRU information, then log into one MF106 via telnet or SSH and use the command
shelf_fru_validation with option -p to specify which shelf FRU information is correct.
Afterwards, reboot the shelf.
Example: Declare shelf FRU information of local shelf manager valid:
# shelf_fru_validation -w -p M1

IP Addresses

The following subsections describe the IP addresses of the shelf manager. There are no pre-
defined IP addresses for the node blades.
The shelf manager has three network interfaces: One on the front panel, one to its own hub and
one to the hub of the other MF106. The shelf manager sets up these interfaces based on the
information found in the shelf manager IP connection record of the shelf FRU information.
