IMPORTANT: The HP Dynamic Smart Array B140i Controller is only available in UEFI Boot Mode.
It cannot be enabled in Legacy BIOS Boot Mode. If the B140i controller is disabled, drives
connected to the system board Mini-SAS connectors operate in AHCI or Legacy mode. Under this
condition:
• The drives cannot be a part of a hardware RAID or a logical drive.
• The Locate, Drive status, and Do not remove LEDs of the affected drives are disabled.
Use BIOS/Platform Configuration (RBSU) in the UEFI System Utilities ("HP UEFI System Utilities" on
page 138) to enable or disable the B140i controller (System Configuration → BIOS/Platform
Configuration (RBSU) → System Options → SATA Controller Options → Embedded SATA
Configuration).
Hot-plug fans
The server supports redundant hot-plug fans to provide proper airflow to the system when a primary fan fails.
