HP Integrity rx8620 Server User Service Guide

NOTE: Fans driven to a high RPM in dense air cannot maintain expected RPM and are
considered bad by the MP leading to a “False Fan Failure” condition.
Power Control
If active, the manageability firmware is responsible for monitoring the power switch on the front
panel. Setting this switch to the ON position is a signal to the MP to turn on 48 V DC power to
the server. The PE command can also be used to send this signal. This signal does not always
generate a transition to the powered state. The following conditions prevent the manageability
firmware from applying 48 V DC power to the server:
• Insufficient number of active bulk power supplies
• Insufficient number of I/O fans
• Insufficient number of main fans
• Ambient temperature is in an OVERTEMP HIGH condition
Unless one of the following conditions occurs, 48 V DC power to the server is maintained:
• A main fan failure causes there to be an insufficient number of main fans.
• A I/O fan failure causes there to be an insufficient number of I/O fans.
• Ambient temperature reaches an OVERTEMP HIGH condition.
• The front panel power switch is turned OFF.
• The PE command is issued to the manageability firmware to turn off power to the server
cabinet.
