Power On System After Service

Follow this procedure after you have serviced these components:

The chassis is set by default to power on automatically when AC power is connected to the chassis. However, if you have changed this default setting so that the chassis does not power on automatically, you can power on the system by using the Power button, by issuing software commands through the Chassis Monitoring Module (CMM) web interface, or by using the command-line interface (CLI).

This topic includes the following sections:

Power Cord Connections

Ensure that the power cords are connected to the AC power inlets on the rear of the chassis. These power cords must be rated at 16A or 20A (depending on geographic location) and must have a plug that meets the requirements of the data center installation. The connection to the AC inlet on the system is location specific.

Sun Blade 8000 P Chassis:

  • Americas Domestic – NEMA L6-20P to IEC320-C19; 13 ft (4m); Sun part number X5074A-Z

  • International – IEC309 to IEC320-C19; 13 ft (4m); Sun part number X5075A-Z

  • Preinstalled in a rack with a power distribution unit – IEC320-C20 to IEC320-C19; 4.9 ft (1.5m) Sun part number X5076A-Z; 6.5 ft (2m) Sun part number X50477-X

Powering On the System Automatically

  1. Verify that the power cords are properly connected to the AC inlets on the chassis and to the cabinet power distribution unit (PDU) or other power source.

    When the chassis is first connected to AC power, this sequence of events starts:

    • The power supplies produce 12-volt standby power.

    • The CMMs receive 12-volt standby power and come out of reset.

    • The processors begin to execute uBoot on the CMM and set the OK indicator on the CMM to a Slow Blink state.

    • When the CMMs have booted, the active CMM sets the OK indicator on the Front Indicator Module (FIM) and Rear Indicator Module (RIM) to the Standby Blink state, indicating that the chassis is now ready for full power-on. The CMM OK indicator turns to Steady On.

    The chassis will then automatically power on by default if the CMM Power-On Policy is enabled. For information about this policy, see CMM Power-On Policy.

    Note

    The chassis will power on only when at least three power supply modules are energized and the CMM is configured to enable automatic power-on of the chassis.

  2. Verify that the green OK indicator on the FIM or RIM is in the Steady On state.

    When the chassis has been fully powered on, the OK indicator will remain illuminated. The Steady On OK LED indicates that the power supplies are energized and that 48V power is supplied to the fan array, Sun Blade Server Modules (blades), and the Network Express Modules (NEMs).

Powering On the System Using the Power Button

Use this procedure if the chassis does not power on automatically.

  1. Verify that the power cords are properly connected to the AC inlets on the chassis and to the cabinet power distribution unit (PDU) or other power source.

    Verify that the OK indicator on the FIM or RIM is in the Standby Blink state.

  2. Press the Power button on the FIM or RIM.

    This action energizes the power supplies, which provide 48V power to the fan array, blades, and the NEMs.

  3. Verify that the green OK indicator on the FIM or RIM is in the Steady On state.

    When the chassis has been fully powered on, the OK indicator will remain illuminated. The Steady On OK LED indicates that the power supplies are energized and the 48V power is supplied to the components.

Powering On the System Using the Web Interface

  1. Log in to the ILOM web interface on the 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 the Power On value to power on the host.

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

Powering on the System Using the CLI

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

  2. Type start /CH

    This command powers on the chassis and is only available to Administrators.
