The default PSU settings are as follows:
● If the load on the active PSU is more than 50 percent of PSU rated power wattage, then the redundant PSU is switched to
the active state.
● If the load on the active PSU falls below 20 percent of PSU rated power wattage, then the redundant PSU is switched to
the sleep state.
You can configure the hot spare feature by using the iDRAC settings. For more information, see the iDRAC User’s Guide
available at Dell.com/idracmanuals.
Trusted platform module
The Trusted Platform Module (TPM) is used to generate and store keys, protect or authenticate passwords, and create
and store digital certificates. The Intel’s TXT (Trusted Execution Technology) functionality along with Microsoft’s Platform
Assurance feature in Windows Operating System is supported. TPM can also be used to enable the BitLocker hard drive
encryption feature in Windows Operating System.
The TPM chip is on the Plug-in Module (PIM) and bound only to one system board.
The system board has a connector for the plug-in module, and it is factory-installed.
Figure 35. Trusted platform module
There are four types of TPM chip options:
● No TPM
● TPM 1.2 Nuvoton FIPS-CC-TCG
● TPM TPM 2.0 Nuvoton FIPS-CC-TCG
● TPM 2.0 NationZ
NOTE:
In a scenario where both the control panel and system board are dispatched, Dell recommends you to replace the
control panel first and try to turn on the system to complete the Easy Restore process (Service Tag, licenses, copy to the
new control panel). Replace the system board.
