Changing the Power Policy option to the default settings after
loading UEFI defaults
The default settings for the Power Policy option are set by the IMM2.
To change the Power Policy option to the default settings, complete the following
steps.
1. Turn on the server.
Note: Approximately 20 seconds after the server is connected to AC power, the
power-control button becomes active.
2. When the prompt <F1> Setup is displayed, press F1. If you have set an
administrator password, you must type the administrator password to access
the full Setup utility menu. If you do not type the administrator password, a
limited Setup utility menu is available.
3. Select System Settings > Integrated Management Module, then set Power
Restore Policy setting to Restore.
4. Go back to System Configuration and Boot Management > Save Settings.
5. Go back and check the Power Policy setting to verify that it is set to Restore
(the default).
Attention: If you set an administrator password and then forget it, there is no
way to change, override, or remove it. You must replace the system board.
Using the integrated management module
The integrated management module (IMM) is a second generation of the functions
that were formerly provided by the baseboard management controller hardware. It
combines service processor functions, video controller, and remote presence
function in a single chip.
The IMM supports the following basic systems-management features:
v Active Energy Manager.
v Alerts (in-band and out-of-band alerting, PET traps - IPMI style, SNMP, e-mail).
v Auto Boot Failure Recovery (ABR).
v Automatic microprocessor disable on failure and restart in a two-microprocessor
configuration when one microprocessor signals an internal error. When one of
the microprocessors fail, the server will disable the failing microprocessor and
restart with the other microprocessor.
v Automatic Server Restart (ASR) when POST is not complete or the operating
system hangs and the operating system watchdog timer times-out. The IMM
might be configured to watch for the operating system watchdog timer and
reboot the system after a timeout, if the ASR feature is enabled. Otherwise, the
IMM allows the administrator to generate a nonmaskable interrupt (NMI) by
pressing an NMI button on the light path diagnostics panel for an
operating-system memory dump. ASR is supported by IPMI.
v Boot sequence manipulation.
v Command-line interface.
v Configuration save and restore.
v DIMM error assistance. The Unified Extensible Firmware Interface (UEFI)
disables a failing DIMM that is detected during POST, and the IMM lights the
associated system error LED and the failing DIMM error LED.
