The motherboard assembly must be removed in order to access the following components:
Power distribution board
Power supply backplane (SPARC Enterprise T5220 server)
Note - This procedure requires removing the server from the rack.
Caution - The server is heavy. Two people are required to remove it from the rack.
The SCC module contains system host ID and MAC addresses. If you replace the motherboard, transfer the SCC module from the old motherboard to the new motherboard. This action will retain the server’s original host ID and MAC address.
Note - The firmware configuration variable settings are not stored in the SCC module. If you replace the motherboard, these settings will become the factory default settings. If possible, keep a record of any firmware variables that have been changed from the factory default values so you can configure the new motherboard with those settings.
