• The server comes standard with one 430-watt hot-swap power supply. The input voltage is 110 V ac or
220 V ac auto-sensing.
• These power supplies are designed for parallel operation. In the event of a power-supply failure, the
redundant power supply continues to power the system. The server supports a maximum of two power
supplies.
• The server can run fully configured with one power supply. For redundancy support, you must install the
second hot-swap power supply.
Note: You cannot mix high-efficiency and non-high-efficiency power supplies in the server.
