Hot-Plug Power Supplies - Compaq ProLiant ML570 Maintenance And Service Manual

Hot-Plug Power Supplies

The ProLiant ML570 server uses a hot-plug, 450-watt power supply. Only one power supply is
required for each single, six-bay drive cage. The power supply must be located in the primary
bay. A second power supply is considered redundant for a single hard drive cage configuration,
but necessary for a two hard drive cage configuration. When two hard drive cages are used, a
third power supply is supported as an option for redundancy. The location of the power supplies
is shown in Figure 2-41 and the power supply bay configuration is described in Table 2-9.
