v Make sure that the devices that you are installing are supported. For a list of
supported devices for the server, see "Parts listing for file modules" in the IBM
Storwize V7000 Unified Information Center.
v 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-03.ibm.com/systems/bladecenter/
resources/powerconfig.html.
v The server comes with one hot-swap 12-volt output power supply that connects
to power supply bay 1. The input voltage is 110 V ac or 220 V ac auto-sensing.
v You cannot mix 460-watt and 675-watt power supplies, high-efficiency and
non-high-efficiency power supplies, or ac and dc power supplies in the server.
v The following information applies when you install 460-watt power supplies in
the server:
– A warning message is generated if the total power consumption exceeds 400
watts and the server only has one operational 460-watt power supply. In this
case, the server can still operate under normal condition. Before you install
additional components in the server, you must install an additional power
supply
– The server automatically shuts down if the total power consumption exceeds
the total power supply output capacity
– You can enable the power capping feature in the Setup utility to control and
monitor power consumption in the server (see the "Setup utility" information
available in "Troubleshooting the System x3650" in the IBM Storwize V7000
Unified Information Center.)
The following table shows the system status when you install 460-watt power
supplies in the server:

v Power supply 1 is the default/primary power supply. If power supply 1 fails,
you must replace the power supply immediately.
v You can order an optional power supply for redundancy.
v 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.
v For instructions on how to install a hot-swap dc power supply, refer to the
documentation that comes with the dc power supply.
