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.
