Contact the maintenance personnel of NEC to replace or upgrade the system.
1.2.1.Adding Processors
At least one processor is required in the main cabinet. Using the CPU expansion feature, the Itanium2 processor can be added one by one. Up to four processors can be installed for each cell. To install more than four processors, the cell must be added first using the cell expansion feature. A maximum of 32 processors can be installed in the main cabinet.
1.2.2.Expanding Memory Capacity
The minimum required memory capacity in the main cabinet is 2GB. This memory capacity can be expanded up to 128GB for each cell. This means a maximum of 1TB of memory can be installed in the main cabinet.
2GB, 4GB and 8GB memories are supported at present. For other memories, inquire the sales personnel of NEC.
1.2.3.Adding Cells
At least one cell is required in the main cabinet. For system expansion, such as the addition of processors, the cell must be added first using the cell expansion feature. Up to 8 cells can be installed in the main cabinet.
