page 107 for the location of the midplane connector on the I/O board, the memory
board, and the processor controller board, respectively.
Note:
The midplane is not a user-removable component. If the midplane requires
service, contact your IBM service technician, IBM reseller, or IBM marketing
representative.
Processor controller board
The processor controller board manages the server processors on the processor
daughterboards.
The processor controller board contains the connectors for the standard processor
daughterboard, the optional processor daughterboard, the cache coherency filter
card A, the cache coherency filter card B, and the LED card.
See “Processor-controller board component locations” on page 107 for a layout of
the processor controller board.
Processor daughterboard
The processor daughterboard houses the server processors and is connected to
the processor controller board.
Your server supports two
processor daughterboards
. Each processor
daughterboard contains the connectors for four processors.
See “Installing a processor” on page 56 for instructions on installing a processor on
a processor daughterboard. See “Processor-daughterboard component locations”
on page 109 for a layout of the processor daughterboard.
Memory board
The memory board houses the dual inline memory modules (DIMMs). The DIMMs
contain the system memory.
Your server supports two memory boards. Each memory board contains the
connectors for 16 DIMMs.
See “Installing DIMMs and memory boards” on page 52 for instructions on
installing a DIMM on a memory board, and installing a memory board in the server.
See “Memory board component locations” on page 105 for a layout of the memory
board.
