Power Off System Before Service

Although most components of the Sun Blade 8000 Series are hot-pluggable, you must remove power from the chassis to service these components:

In addition, certain components can be serviced only when power has been removed from the component, and in some cases, if the system is disassembled adequately. For example, before you can service the DIMMs, FB-DIMMs, CPUs, or heatsinks, you must physically remove the blade from the chassis, which necessitates removal of the blade power.

You can use either the ILOM web interface or the command-line interface (CLI) to power off the system.

Caution

Do not attempt to use the chassis Power button to power off the system. The Power button, which is located on the Front Indicator Module and the Rear Indicator Module, is disabled by default for powering off the system. This prevents unauthorized users from powering off the system.

Powering Off the System Using the Web Interface

  1. Log in to the ILOM web interface on the Chassis Monitoring Module (CMM).

  2. Select the CMM view from the left panel.

  3. From the Remote Control tab, choose the Remote Power Control tab.

  4. Select the radio button next to Chassis (/CH).

  5. Use the drop-down list to select a new power state for the chassis.

    The chassis' current power state appears in the Current State column.

    1. Select one of the following values:

      • Immediate Power Off – Select to power off the server without a graceful shutdown of the host operating systems. Using this option could result in data loss as the host operating systems are not powered off gracefully.

      • Graceful Shutdown and Power Off – Select to gracefully shut down the operating system before the host is powered off.

    2. In the confirmation dialog box, click OK to confirm the change.

Powering Off the System Using the CLI

  1. Log in to the ILOM CLI on the CMM.

  2. Type one of the following commands:.

    • stop /CH – This command initiates an orderly shutdown of the chassis and is only available to Administrators. This command requests a graceful shutdown of the operating systems, then powers off the chassis.

    • stop -f /CH – This command powers off the server without a graceful shutdown of the host operating systems. Using the -f option could result in data loss as the host operating systems are not powered off gracefully.
