*1 The XSCF DUAL control cable, XSCF BB control cable, and crossbar cable need to be connected.
*2 Use the initbb command to remove a SPARC M12-2S when every connected SPARC M12-2S is in the hot state. After the SPARC M12-2S initialized by the initbb command enters the cold state, remove it from the system.
