Replacing the hot-swap power supply

This procedure applies only to the 5U server model with hot-swap power supplies.

The following items describe the type of power supply that the server supports and other information that you must consider when you install a power supply:
  • To confirm that the server supports the power supply that you are installing, see the Lenovo ServerProven website.
  • 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.
