See "
NIC Status Indicator (Link/Activity)
3 Power and System Board Indicator Codes" on page 21.
CAUTION: At least one power supply must be installed for the system to operate.
Operating the system with only one power supply installed for extended periods of
time can cause the system to overheat.
4 Reseat the power supply by removing and reinstalling it. See "Power
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.
If the problem persists, replace the faulty power supply.
