System Security Settings details
The
System Security Settings
screen details are explained as follows:
NOTE:
The Dell EMC Storage NX3240 system supports only BIOS mode. You must not change the boot mode to UEFI because
the system does not boot.
Option
Description
In-Band
Manageability
Interface
When set to
Disabled
, this setting will hide the Management Engine's (ME), HECI devices, and the system's IPMI
devices from the operating system. This prevents the operating system from changing the ME power capping
settings, and blocks access to all in-band management tools. All management should be managed through out-of-
band. This option is set to
Enabled
by default.
NOTE:
BIOS update requires HECI devices to be operational and DUP updates require IPMI interface to
be operational. This setting needs to be set to Enabled to avoid updating errors.
Intel(R) AES-NI
Improves the speed of applications by performing encryption and decryption by using the Advanced Encryption
Standard Instruction Set (AES-NI). This option is set to
Enabled
by default.
System Password
Sets the system password. This option is set to
Enabled
by default and is read-only if the password jumper is not
installed in the system.
Setup Password
Sets the setup password. This option is read-only if the password jumper is not installed in the system.
Password Status
Locks the system password. This option is set to
Unlocked
by default.
Power Button
Enables or disables the power button on the front of the system. This option is set to
Enabled
by default.
AC Power Recovery
Sets how the system behaves after AC power is restored to the system. This option is set to

by default.
AC Power Recovery
Delay
Sets the time delay for the system to power up after AC power is restored to the system. This option is set to

(60 s to 240 s)
Sets the
User Defined Delay
option when the
User Defined
option for
AC Power Recovery Delay
is selected.
UEFI Variable
Access
Provides varying degrees of securing UEFI variables. When set to
Standard
(the default), UEFI variables are
accessible in the operating system per the UEFI specification. When set to
Controlled
, selected UEFI variables are
protected in the environment and new UEFI boot entries are forced to be at the end of the current boot order.
Secure Boot
Enables Secure Boot, where the BIOS authenticates each pre-boot image by using the certificates in the Secure
Boot Policy. Secure Boot is set to
Disabled
by default.
Secure Boot Policy
When Secure Boot policy is set to
Standard
, the BIOS uses the system manufacturer’s key and certificates to
authenticate pre-boot images. When Secure Boot policy is set to
Custom
, the BIOS uses the user-defined key and
certificates. Secure Boot policy is set to
Standard
by default.
Secure Boot Mode
Configures how the BIOS uses the Secure Boot Policy Objects (PK, KEK, db, dbx).
If the current mode is set to
Deployed Mode
, the available options are
User Mode
and
Deployed Mode
. If the
current mode is set to
User Mode
, the available options are
User Mode
,
Audit Mode
, and
Deployed Mode
.
Options
Description
