Set the hard-disk-drive partitions switch to the correct position for your cabling configuration
by using the table in this section. The hard-disk-drive partitions switch is located at the rear of
the 58/02 expansion unit, just below the SAS connectors.
6.
Cable the expansion unit to the server as follows:
Notes:
You might need to power off the server before connecting the cables. For information about
powering off the server, see Overview for I/O expansion units.
This unit uses 12X Double Data Rate (DDR) and system power control network (SPCN) cables to
connect to the server.
Do not perform 12X DDR cable configuration changes, such as moving existing expansion units to
different GX adapters at the same time you add new expansion units.
If you are adding a new expansion unit or migrating expansion units from another IBM Power
Systems
™
server, you might not be able to allocate the expansion unit resources to logical
partitions on the new server until an SPCN firmware update is completed for the expansion units.
a.
Complete all applicable prerequisites for installing your expansion units. For detailed procedures
related to preparing to connect your expansion units, see Prepare to connect your expansion units.
