NOTICE: The system requires one power supply for the system to operate normally. The system is in the redundant mode when two power supplies

are installed and both power supplies are connected to an AC power source. Remove and replace only one power supply at a time in a system that is

powered on. Operating the system with only one power supply installed and without a power supply blank installed for extended periods of time can

cause the system to overheat.

NOTICE: If you connect the system to a power source in the range of 120 to 220 VAC, the second power supply serves as a redundant, hot-plug power

source.

NOTE: On your rack system, you may have to unlatch and lift the cable management arm if it interferes with power supply removal. For information

about the cable management arm, see the system's Rack Installation Guide.
