Some models of the server use AC input power and other models use DC input power. For input power specifications for both AC and DC models, refer to the Sun SPARC Enterprise T5120 and T5220 Server Site Planning Guide.
The server models that run on DC input power require you to build the input power cable to specific safety guidelines. For instructions on building the DC power cables and the safety guidelines, refer to the Sun SPARC Enterprise T5120 and T5220 Server Installation Guide.
Note - The instructions in this manual use the AC server models as examples. However, unless noted otherwise, the instructions also apply to the DC server models.
Each power supply is provided with a set of three LEDs, which can be viewed on the back panel of the system.

The following table describes the three power supply LEDs

Note - If a power supply fails and you do not have a replacement available, leave the failed power supply installed to ensure proper airflow in the server.
