3.4 System-Stopped Maintenance
3.4 System-Stopped Maintenance
The type of maintenance performed with all the physical partitions on the system stopped is referred to as system-stopped maintenance. There are two types of maintenance work for system-stopped/cold maintenance, as follows.
- Maintenance using the maintenance menu when only the SPARC M12-2S/M10-4S connecting to the crossbar box with cables to be replaced is in the cold state
- Maintenance without using the maintenance menu when all the crossbar boxes and the SPARC M12-2S/M10-4S are in the cold state
Table 3-3, Figure 3-5, Figure 3-6, and Figure 3-7 show FRUs of the crossbar box with system-stopped maintenance enabled.
-: Maintenance cannot be performed. |

| *1 Maintenance is performed on the XSCF in the standby state or a slave XSCF. If the XSCF is operating as the master XSCF, switch it to a standby XSCF. *2 Hot maintenance is enabled only when you perform maintenance work on an XSCF BB control cable connecting crossbar boxes to each other. *3 This is supported only for a redundant configuration. *4 When replacing the microSD card at the same time as the XSCF unit of a crossbar box in a SPARC M10 system, replace them during system-stopped/hot maintenance. *5 To maintain the XSCF BB control cable and crossbar cable that connect the crossbar box to the chassis of the physical partition, the connected chassis must be powered off. *6 Replacement is available only when all the chassis in the building block configuration are powered off. |
