Minimum to POST and system management
configuration validation
This section describes the minimum to POST system requirement and system management configuration validation of the Dell
EMC system.
Topics:
• Minimum configuration to POST
• Configuration validation
Minimum configuration to POST
The components listed below are the minimum configuration to POST:
● Processor
● One memory module (DIMM) in socket A1
● One power supply unit
● System board
Configuration validation
The new generation of PowerEdge systems have added interconnect flexibility and advanced iDRAC management features to
collect precise system configuration information and report configuration errors.
When the system is powered on, information about installed cables, risers, backplanes, floating card (adapter PERC like
BOSS), and processor is obtained from the CPLD and backplane memory maps is analyzed. This information forms a unique
configuration, which is compared with one of the qualified configurations stored in a table maintained by iDRAC.
One or more sensors are assigned to each of the configuration elements. During POST, any configuration validation error is
logged in the System Event Log (SEL)/LifeCycle (LC) log. The reported events are categorized in the configuration validation
error table.

Error Description Possible cause and
recommendations
Example
Config Error A configuration element within the
closest match contains something that is
unexpected and does not match any Dell
qualified configuration.
Wrong configuration Config Error: Backplane cable
CTRS_SRC_SA1 and BP-DST_SA1
The element reported
in HWC8010 errors are
assembled incorrectly.
Verify element (cable,
risers, etc) placement in
the system.
Config Error : SL Cable

Config
Missing
iDRAC found a configuration element
missing within the closest match
detected.
Missing or damaged cable,
