Power On System Chassis for First Time

The Sun Blade 8000 Series Chassis, by default, receive main power as soon as the chassis power supplies receive power and the CMM boots up. At this time, the NEM and fan modules in the chassis automatically power-on. The Sun Blade Server Modules and their associated EMs in the chassis do not automatically power-on. These modules, by default, receive standby power. You can manually apply main power to these modules (blade and associated EM) via the blade Power button or the blade ILOM remote power controls.

Note

By default, the policy for the auto-power-on chassis option is shipped enabled in ILOM. If you disable the auto-power-on chassis policy, then only the CMMs receive power. You can apply man power to the chassis via the chassis Power button (or via the CMM ILOM chassis remote power controls if network connectivity has been established.)

Note

As of ILOM 1.1.5, the BIOS no longer has a blade default auto-power-on option. The Blade Power-on Policy in ILOM determines the power state of the blade at boot time. By default, the option “Set host power to last power state on boot” is shipped enabled in the Blade Power-On Policy. When the blade SP boots up for the first time (out-of-box), the host power state on the blade is OFF. The blade SP tracks the main power state and will restore the blade to its previous power state following a power interruption or a rebooting of the blade SP. For more information about the system power-on policies, see About the CMM and Blade Power-on Policies.

Note

The Sun Blade 8000 and 8000 P Chassis must have at least three or more power supplies receiving power (from a MPS or direct cabling) for the auto-power-on policy to take effect. If fewer than three chassis power supplies are receiving power, you will not be able to power on the system chassis.

The following procedures describe how to:

Verify System Chassis Is Powered On

  1. Ensure that the AC power cables are attached from the Power Interface module to a PDU.

    For details, see Attach Power Cables.

  2. Ensure that main power is applied to the system chassis.

    The OK power LED illuminates a solid green light. The OK power LED is located on the front and rear panel of the chassis.

    Note

    By default, the Auto-Power-On Policy setting in ILOM is shipped enabled for the system chassis. When this option is enabled, the system chassis automatically powers-on the NEMs and Fan modules (after power is provided to the power supplies). Standby (12V) power, by default (out-of-box), is applied to the blade and associated EM, if applicable. For more information about the blade power policy, see Blade Power Policy.

Chassis and CMM Not Receiving Main Power

If the system chassis and CMM are not receiving main power, consider the following:

  • If main power was not applied to the chassis and CMM (chassis OK LEDs do not illuminate green), ensure that the power cables from the Power Interface module are attached to an active MPS (or if direct cabling is used, ensure power is being provided to the direct cabling). For details, see Attach Power Cables.

  • If the OK power LED flashes on the chassis and the Auto-Power-On Chassis Policy option has been disabled in the ILOM, press the Power button on the system chassis to apply main power.

Note

You can maintain the policy for the Auto-Power-On Chassis setting in ILOM as soon as network connectivity is established. To access the Chassis Monitoring Module Policy options, (1) connect to the CMM IP address and log into ILOM, (2) in the ILOM window select CMM in the left navigation panel, then (3) select Configuration -> Policy in the right panel.

To verify the power state of a Sun Blade Server Module, see the following procedure.

Verify Sun Blade Server Module Power State

  1. Verify that the system chassis is powered on.

    A solid green light should be visible from the OK power LED.

    If the chassis has not been powered on, see Ensure the System Chassis Is Powered On.

  2. Determine whether the Sun Blade Server Module is receiving Standby Power or Main Power:

    • Blade SP - Standby Power. The OK power LED on the blade front panel illuminates a standby blink (on/off cycle at 1 Hz). This power state indicates that the blade SP is powered ON but the blade host is powered OFF.

      You can apply main power to the blade host via the blade Power button or ILOM remote power controls.

      Note

      If the blade host does not power on, verify that the CMM is powered on, then reset the blade.

    • Blade Host - Main Power. The OK power LED on the blade front panel illuminates a green solid light. This power state indicates the blade SP and host are both powered ON.

If Blade Is Not Receiving Power

If the blade is not receiving power, consider the following:

  • The blade SP power policy in ILOM determines whether or not main power is applied to the blade SP at boot time. By default (out of the box), standby power is automatically applied to the blade SP. For more information about the blade power policy options, see Blade Power Policy.

  • If the blade is not receiving power (based on power policy in effect), reboot the CMM then reboot the blade.

  • If the blade is still not powering on after rebooting the CMM, see the following topics:

Note

Blade and EM connections are powered on and off as a pair. When power is disabled on a blade, it is also disabled, if applicable, on its associated EM.

Note

The blade power-on state prior to ILOM 1.1.5 was controlled in the BIOS. The earlier blade BIOS firmware power-on state was shipped enabled – causing the blade to automatically power-on upon receiving power from the chassis.

Tip

Alternatively, you can power on and off blades from ILOM as soon as network connectivity to the system is established. To power on or off a blade from ILOM, connect to the blade SP IP address and log into ILOM, then select Remote Power -> Remote Power Control.
