states of the LEDs. The green LED will normally illuminate first. The normal state 
is Green On, Amber On.

If a node repeatedly and spontaneously reboots when attempting to load the 
InfiniPath driver, it may be a symptom that its InfiniPath interconnect board is not 
well seated in the HTX or PCIe slot.

Some HTX motherboards may require that 2 or more of the CPUs be in use for the 
HTX InfiniPath card to be recognized. This is most evident in four-socket 
motherboards.

This section covers issues related to improper BIOS settings.The two most 
important settings are:

■

ACPI needs to be enabled

■

MTRR mapping needs to be set to “Discrete”

If ACPI has been disabled, it may result in initialization problems, as described in 

An improper setting for MTRR mapping can result in reduced performance. See 

, and 

 for details.

BIOS settings on IBM Blade Center H (Power) systems do not need 
adjustment.
