NX5820 and NX5820 K Memory

The NX5820 and NX5820 K utilizes the MSA and two styles of MSK memory boards for various system configurations. Each style of memory is unique to a range of system styles as follows:

•The MSA104-192 board is configured in NX5820 system styles NX5821-31 through NX5822-72, and in NX5820 K system styles NX5821-1D1 and NX5822-2D2.

•The MSK208-384 board is configured in NX5820 system styles NX5822-73 through NX5822-76, and in NX5820 K system styles NX5822-2D3 through NX5822-2D6.

•The MSK412-384 board is configured in NX5820 system styles NX5822-77 and NX5822- 78, and in NX5820 K system styles NX5822-2D7 through NX5822-2DA.

Table 3-1 shows the specific type and quantity of memory boards configured.
