3. Based on the model of your server (AC or DC), apply power to the power
supply in one of the following ways:

■ DC server models – Turn on the power using the circuit breaker at the power
source.
Caution – For server models with DC input power, do not disconnect and reconnect
the power cable at the Wago connector on the server DC power supply unit. Instead,
control the input power using the circuit breaker at the power source.
