Power supplies
The server supports up to three 1100-watt, hot-swap power supplies that support N+N or N+1 redundancy
depending on the configuration:
If only two or three processors are installed or four processors less than 140 W are installed, then one
power supply is required and the second supply can be redundant if installed (N+N where N=1)
If four 140W processors are installed, then two power supplies are required for a fully-populated
server with no redundancy (or three power supplies can be installed with the third redundant N+1,
where N=2)
If four 140W processors are installed, only one power supply can be installed with no redundancy (or
two power supplies can be installed with the second redundant, N+1 where N=1) provided these limits
are met:
Maximum 16 DIMMs
Maxumum 4 disk drives
