Item Maintenance work procedure Reference
1 Accessing a CPU memory unit "9.5.1  Accessing a CPU memory unit"
2 Removing a CPU memory unit from the chassis "9.5.2  Removing a CPU memory unit from the chassis"
3 Removing the CPU memory unit upper or filler unit "9.5.3  Removing the CPU memory unit upper"
4 Switching the microSD card (*1) "9.7  Switching the microSD Card"
5 Removing memory "9.8  Removing Memory"
6 Installing memory (*2) "9.9  Installing Memory"
7 Installing the CPU memory unit upper or filler unit "9.10.1  Installing the CPU memory unit upper"
8 Installing the CPU memory unit in the chassis "9.10.2  Installing the CPU memory unit in the chassis"
*1 You can shorten the maintenance time by switching the microSD card when replacing the CPU memory unit lower. You do not need to switch the microSD card when replacing the CPU memory unit upper.
*2 When replacing the CPU memory unit, mount memory in the same mounting locations as in the replaced unit.
