Power the system off and then power it on.

The release notes typically specify one of the following methods:

• A warm restart by running an operating system command to reboot the system.

• A cold restart by running an operating system command to power off the system and then power on by using the BMC or pressing the power button on the chassis.

• A cold restart that also requires removing power such as unplugging the power cables or power cycling the power distribution unit sockets. This is also a cold restart, but sometimes necessary to update power-sensitive components.
