Troubleshooting Your System
NOTICE:
You can hot-plug the redundant 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 with only one power
supply installed for extended periods of time can cause the system to overheat.
4
Ensure that the power supply is properly installed by removing and
reinstalling it. See "Installing a Redundant Power Supply" on page 77.
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" on page 17.
5
If the problem persists, remove the faulty power supply. See "Removing a
Redundant Power Supply" on page 76.
6
