Lenovo x3530 M4 Installation And Service Manual page 71

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 http://www.lenovo.com/
serverproven/.
• Before you install an additional power supply or replace a power supply with one of a
different wattage, you may use the IBM Power Configurator utility to determine current
system power consumption. For more information and to download the utility, go to
http://www.ibm.com/systems/bladecenter/resources/powerconfig.html.
• 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 fixed 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.
