Troubleshooting Your System
157
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 can cause the system to overheat.
2
Remove the faulty power supply. See "Power Supplies" on page 73.
3
Ensure that the power supply is properly installed by removing and
reinstalling it. See "Power Supplies" on page 73.
NOTE:
After installing a new 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 19.
If the problem persists, see "Getting Help" on page 181.
