SW1 instructions for quad-core 3.1 GHz or greater and six-

core processors

CAUTION:

All supported AMD Opteron quad-core processors 3.1 GHz or greater and all

supported AMD Opteron six-core processors require the system maintenance switch,

located on the I/O backplane, (SW1) position 5 to be in the

On

position.

CAUTION:

HP recommends updating to the latest version of firmware. Earlier firmware

versions might not validate the required switch setting for these processors.

NOTE:

Six-core AMD Opteron Processors might show a 1 MB reduction in available L3

cache when performance enhancing HT Assist is enabled because HT Assist requires 1MB

of L3 cache per CPU to operate.

Installing a processor

The server supports a four- or eight-processor configuration.

CAUTION:

The cell filler is

required

in cells 3 - 6 in a four-processor configuration.

CAUTION:

To prevent damage to electrical components, properly ground the server before

beginning any installation procedure. Improper grounding can cause electrostatic

discharge.

CAUTION:

To avoid damage to the processor and system board, only authorized

personnel should attempt to replace or install the processor in this server.

CAUTION:

To prevent possible server malfunction and damage to the equipment,

multiprocessor configurations must contain processors with the same part number.
