*1: For a single-chassis configuration, the inactive/cold maintenance procedure is the same as that for stopping the system, therefore see
the procedure for system-stopped maintenance.
*2: It is necessary to use dynamic reconfiguration (DR) to disconnect a chassis requiring maintenance from the physical partition.
*3: Active/hot replacement can be performed only with a redundant configuration.
*4: Supported only for internal disks of devices other than boot devices. If, however, the boot device has a redundant configuration
(RAID configuration), active/hot maintenance is supported.
*5: The types of maintenance for PCIe cards are different from those of other FRUs. For details, see Table 13-1.

*1: If any physical partition mounted on two or more chassis is currently operating, the crossbar box cannot be powered off.
*2: If any physical partition is currently operating, the crossbar box cannot be powered off.
*3: All the physical partitions must be powered off, and the system must be completely shut down.
*4: The XSCF must be configured as a slave before maintenance is started. If the XSCF is operating as the master XSCF, switch it to a
standby XSCF.
*5: Active/hot replacement can be performed only with a redundant configuration.
