Use this information to install a hot-swap power supply.
The following notes 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.
- Before you install an additional power supply or replace a power supply with one of a different wattage, you may use the Power Configurator utility to determine current system power consumption. For more information and to download the utility, go to the IBM Power Configurator website.
- The server comes standard with one of the following power supplies
that connects to power supply bay 1. The input voltage is 100-127
V ac or 200-240 V ac auto-sensing.
- 460-watt non-hot-swap power supply
- 460-watt hot-swap power supply
- 675-watt high-efficiency, hot-swap power supply
Note: You cannot mix 110 V ac and 220 V ac, or 460-watt and 675-watt power supplies in the server, it is not supported. - Power supply 1 is the default/primary power supply. If power supply 1 fails, you must replace the power supply with the same wattage immediately.
- The server supports a maximum of two hot-swap power supplies. 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 can run fully configured with one power supply. For redundancy support, you must install the second hot-swap power supply.

To install a hot-swap power supply, complete the following steps:
- Read the safety information that begins in Safety and Installation guidelines.
- Touch the static-protective package that contains the hot-swap power supply to any unpainted metal surface on the server; then, remove the power supply from the package and place it on a static-protective surface.
- If you are installing a hot-swap power supply into an empty bay,
remove the power-supply filler panel from the power-supply bay. Figure 1. Power supply installation
- Grasp the handle on the rear of the power supply and slide the power supply forward into the power-supply bay until it clicks. Make sure that the power supply connects firmly into the power-supply connector.
- Route the power cord through the cable retainer clip so that it does not accidentally become disconnected
- Connect the power cord for the new power supply to the power-cord connector on the power supply.
- Connect the other end of the power cord to a properly grounded electrical outlet.
- Make sure that the ac power LED and the dc power LED on the power supply are lit, indicating that the power supply is operating correctly. The two green LEDs are to the right of the power-cord connector.
