13.3.6.3 SMBAlert# Signal<br />
This signal indicates that the power supply is experiencing a problem that the user should<br />
investigate. This shall be asserted due to Critical events or Warning events. The signal shall<br />
activate in the case of critical component temperature reached a warning threshold (see sec.<br />
4.10), general failure, over-current, over-voltage, under-voltage, failed fan. This signal may also<br />
indicate the power supply is reaching its end of life or is operating in an environment exceeding<br />
the specified limits.<br />
This signal is to be asserted in parallel with LED turning solid Amber or blink Amber.<br />

13.3.7 Thermal CLST<br />
The power supply shall assert the SMBAlert signal when a temperature sensor crosses a<br />
warning threshold. Refer to the <strong>Intel</strong> ® Common Hardware & Firmware Requirements <strong>for</strong> CRPS<br />
Power Supplier <strong>for</strong> detailed requirements.<br />
13.3.8 Power Supply Diagnostic “Black Box”<br />
The power supply saves the latest PMBus data and other pertinent data into nonvolatile<br />
memory when a critical event shuts down the power supply. This data is accessible via the<br />
SMBus interface with an external source providing power to the 12Vstby output.<br />
Refer to the <strong>Intel</strong> “Common Hardware & Firmware Requirements <strong>for</strong> CRPS Power Supplier” <strong>for</strong><br />
detailed requirements.<br />
13.3.9 Firmware Uploader<br />
The power supply has the capability to update its firmware via the PMBus interface while it is in<br />
standby mode. This FW can be updated when in the system and in standby mode and outside<br />
the system with power applied to the 12Vstby pins.<br />
Refer to the <strong>Intel</strong> Common Hardware & Firmware Requirements <strong>for</strong> CRPS Power Supplier <strong>for</strong><br />
detailed requirements.<br />
13.4 Lower Power Common Redundant Power Distribution Board (PDB)<br />
The Power Distribution Board (PDB) <strong>for</strong> <strong>Intel</strong> ® Server Chassis P4000M supports the Common<br />
Redundant power supply in a 1+1 redundant configuration. The PDB is designed to plug directly<br />
to the output connector of the PS and it contains 4 DC/DC power converters to produce other<br />
