DDR3 compute book
Use this information for an overview of the DDR3 compute book.
The DDR3 compute book is in the front of the server. Each DDR3 compute book
must have a minimum of one microprocessor, one DIMM, and one fan-pack
installed. It provides the following connectors and slots:
v One microprocessor socket
v 24 DDR3 DIMM connectors
v Two 60 mm counter-rotating fan bays
The DDR3 compute book also provides and a light path button. Press this button
to light the LEDs on the board when the compute book has been removed from
the server. Any LEDs that were light before the compute book was removed from
the server will be lit when the light path button is pressed.
The following illustration shows the front view of the DDR3 compute book:
