3.4.1 Types of Maintenance for FRU Replacement (SPARC M12-2S in a Multiple-BB Configuration)
Table 3-11 lists the replaceable FRUs in the SPARC M12-2S (multiple-BB configuration) and the applicable types of maintenance in the replacement of each FRU.

*1 The replacefru(8) command is used for maintenance. For this purpose, select BB in the maintenance menu.
*2 If the XSCFU requiring maintenance is not running, perform active/hot replacement.
*3 If the XSCFU requiring maintenance is not running, perform inactive/hot replacement.
*4 The replacefru(8) command is used for maintenance. For this purpose, select BB in the maintenance menu. Alternatively, without using the replacefru(8) command, you can replace a FRU after placing every SPARC M12-2S in the building block configuration into the cold state.
*5 If the XSCFU requiring maintenance is not running, perform system-stopped/hot replacement. Alternatively, place every SPARC M12-2S in the building block configuration into the cold state, and replace the XSCFU.
*6 Maintenance is performed using the SR-IOV function, dynamic reconfiguration function for PCIe devices, and PCI Hot Plug function.
*7 This is possible only if the target FRU is in a redundant configuration.
*8 This is possible only for the mirror volumes (RAID1 and RAID1E) when the HDD/SSD used as the boot device is being replaced.
*9 The FRU can be replaced only when every SPARC M12-2S in the building block configuration is in the cold state.
*10 The XSCF DUAL control cable or XSCF BB control cable requiring replacement is connected to the XSCFU. If the READY LED of the XSCFU is off, place every SPARC M12-2S in the building block configuration into the cold state, and replace the cable.
