Compaq AlphaServer ES40 User Manual

System Configuration and Setup 6-49
The system can have the following power configurations:
Single Power Supply. A single power supply is provided with entry-level
systems, such as a system configured with:
•
One or two CPUs
•
One storage cage
Two Power Supplies. Two power supplies are required if the system has
more than two CPUs or if the system has a second storage cage.
Redundant Power Supply. If one power supply fails, the redundant supply
provides power and the system continues to operate normally. A second power
supply adds redundancy for an entry-level system such as the system described
under “Single Power Supply.” A third power supply adds redundancy for a
system that requires two power supplies.
Recommended Installation Order. Generally, power supply 0 is installed
first, power supply 1 second, and power supply 2 third, but the supplies can be
installed in any order. See Figure 6–16. The power supply numbering corre-
sponds to the numbering displayed by the SRM show power command.
