Power Supplies

■

The ProLiant DL760 server has two hot-plug, redundant power supplies.
Depending upon the system load configuration, more than one power
supply may be required to power the system. See Table 2-1 to determine
power supply requirements.

■

Power supplies are load-balancing and have microcontroller monitoring
for advanced health and configuration management.

Refer to Table 2-1 to determine the number of power supplies needed for the
server.
