66 IBM System x3850 X6 and x3950 X6 Planning and Implementation Guide
The system board of the Compute Book also contains a set of error LEDs for each memory
module, which show failed modules when the light path diagnostic button is pressed.
Figure 3-14 shows a diagram with DIMM error LEDs of the Compute Book’s left side.

3.6.2 Compute Book population order
The x3850 X6 server supports these combinations:
򐂰 2 Compute Books
򐂰 4 Compute Books
A configuration of 3 Compute Books is not supported. A configuration of one processor is only
supported in model 3837-A4x. No other server model or CTO configuration supports one
processor.
The x3950 X6 supports these combinations:
򐂰 4 Compute Books
򐂰 6 Compute Books
򐂰 8 Compute Books
Other combinations are not supported.
