Pre-Standby Phase

This

phase

is

entered when

the server

is connected to a power source. The ser

may

or may

not

be fully powered on. This phase is exited when the Power-On Self

Tests (POSTS)

and

configurations

tasks are

completed.

The Pre-Standby phase components are:

ŸSP Initialization

SP performs any necessary hardware and software initializations.

ŸSP POST

SP conducts Power-On Self Tests on its various work and code areas.

Ÿ SP Unattended Start Mode Checks

To assist fault recovery. If unattended start mode is set, the SP automatical reboots the server. SP will not wait for a user-input or power-on command, but will move straight through the phase and into the Bringup Phase. The unattended start mode can be reset by accessing SMS menus, or SP menus.
