## About Lights-Out Management

Lights-out management, also called remote power management, enables you to use a remote console to either partially or fully shut down arrays. Whether partial or full shutdown is requested, the Data Services Platform (DSP) powers off all cards except the management interface cards (MICs). The system has the lights-out management feature enabled by default.

Depending on whether the power relay is enabled, lights-out management also enables you to partially shut down the DSP. This feature allows you to power on the DSP and storage arrays remotely.

The power relay is disabled by default, allowing for a full shutdown only. When the power relay is enabled, a partial shutdown is also possible. For instructons on enabling and disabling the lights-out management feature, use the following procedure:

1. Go to the Sun Web Console page and click Storage Automated Diagnostic Environment
2. Click Service > Service Advisor > X-Options.
