When the hot spare feature is enabled, one of the redundant PSUs is switched to the sleep state. The active PSU supports 100 percent of the system load, thus operating at higher efficiency. The PSU in the sleep state monitors output voltage of the active PSU.
Figure 50. Removing a power supply unit Next step Install the PSU. Installing a power supply unit The procedure for installing AC and DC PSUs is identical. Prerequisites 1 Follow the safety guidelines listed in Safety instructions. 2 For systems that support redundant PSU, ensure that both the PSUs are of the same type and have the same maximum output power. NOTE: The maximum output power (shown in watts) is listed on the PSU label.

Trusted Platform Module Trusted Platform Module (TPM) is a dedicated microprocessor designed to secure hardware by integrating cryptographic keys into devices. Software can use a TPM to authenticate hardware devices. Because each TPM chip has a unique and secret RSA key which is embedded during the manufacture of the TPM, it is capable of performing platform authentication operation. This section contains information about installing the TPM, and initializing the TPM for Intel TXT users.
Figure 54. Installing the TPM Next steps 1 Install the system board. 2 Follow the procedure listed in After working inside your system. Initializing the TPM 1.2 for TXT users 1 While booting your system, press F2 to enter System Setup. 2 On the System Setup Main Menu screen, click System BIOS > System Security Settings. 3 From the TPM Security option, select On with Pre-boot Measurements. 4 From the TPM Command option, select Activate. 5 Save the settings. 6 Restart your system.

Virtual disk not visible to operating system Issue: In RAID mode a virtual disk is not appearing for use by an operating system. Probable cause: Virtual disks will not be presented to the system if they are not native to the controller. Corrective action: Import the virtual disk using Hardware-Independent Imaging (HII). Drive failure Issue: An installed drive is not listed in the BOSS configuration utility. OpenManage reports Physical Disk offline state.
Probable cause: Working as designed, BIOS only allows booting from the first listed boot device (in this case, slot 0) per peripheral controller. This only occurs in legacy BIOS boot mode. Corrective action: Swap the drive in slot 1 to slot 0. CLI reports unsupported features Issue: Several commands, options, or other features listed by the Marvell CLI state that they are unsupported when run.
