Replacing a hot-swap ac power supply
Use this information to replace a hot-swap ac 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:
- 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 https://support.lenovo.com/solutions/lnvo-pwrconf.
- The server comes with one hot-swap 12-volt output power supply that connects to power supply bay 1. The input voltage is 100-127 V ac or 200-240 V ac auto-sensing.
- Power supplies in the server must be with the same power rating or wattage to ensure that the server will operate correctly. For example, you cannot mix 550-watt, 750-watt, 900-watt or 1500-watt power supplies in the server.
- You cannot mix high-efficiency and non-high-efficiency power supplies in the server.
- 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.
- You can order an optional power supply for redundancy.
- 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.
