Troubleshooting a Fan
NOTE: Some software may cause the system time to speed up or slow down. If the system seems to operate normally except for the time kept in the
System Setup program, the problem may be caused by software rather than by a defective battery.
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system.
Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the
computer and protecting against electrostatic discharge.
NOTICE: You can hot-plug the power supplies. One power supply must be installed for the system to operate. The system is in the redundant mode
when two power supplies are installed. Remove and install only one power supply at a time in a system that is powered on. Operating the system for
extended periods of time with only one power supply installed, without a power supply blank installed, can cause the system to overheat.
NOTE: After installing a power supply, allow several seconds for the system to recognize the power supply and to determine if it is working
properly. The power indicator turns green to signify that the power supply is functioning properly. See Power Indicator Codes .
