CHAPTER 3 PRIMEPOWER200 Rackmount (4U) Server
3.4.1 Adding power supply units
IMPORTANT
Adding an optional redundant power supply unit allows hot-swapping of the power supply units.
CAUTION
Unit Damage
Data may be lost if hot-swapping of power supply units is not performed correctly.
Contact the service engineer if a power supply unit must be hot-swapped.
Power supply units (FEP) installed on the PRIMEPOWER200 Rackmount (4U) Server are hot-swappable. To
enable hot-swapping, use the tools (machine administration) contained in the "Enhanced Support Facility" to
perform hot-swapping. For details on how to swap power supply units, refer to the "Machine Administration
Instructions" included with the "Enhanced Support Facility".
3.4.2 Adding CPU modules
A total of two CPU module slots are provided on the PRIMEPOWER200 Rackmount (4U) Systemboard.
When adding CPU modules the following restrictions apply:
Only SPARC64 GP processors can be used.
To ensure they all operate at the same clock speed, have the same cache size and use the same CPU stepping,
the model name must be identical for all CPUs.
CPU modules must be added according to Table 3.4 .
IMPORTANT
Operation for configurations other than those shown in Table 3.4 cannot be guaranteed.
