Figure 3. Management Module — DW612S Enclosure

• Name: System Management Module 2 (SMM2).

• Power Status: Indicates the status of SMM2.

  • SMM2 Reset: After this button is clicked, SMM2 will be reset immediately and ready to operate in 90 seconds.

  • Reset to Default: Restore the SMM2 settings to out-of-factory default, including:

    • SMTP

    • SNMP

    • PEF

    • Network Configuration

    • User Account

    • Account Security

    • Services

    • Web Certificate

    • NTP

    It takes two minutes to complete the Reset to Default process and then SMM2 will be ready to operate.

• Firmware version: The current firmware version.

• Boot-up Flash: Indicates SMM2 current boot up bank. In normal operation, Boot-up flash should always be First. Only when the first flash has a hardware or firmware failure, SMM2 will switch to Second flash.

• Identification LED (ID LED): This blue LED serves to visually locate an enclosure in the rack with the following three options available. To activate an option, choose it from the list and click on Apply or use the corresponding commands.

  • Turn Off

    When this option is activated, SMM2 ID LED would first turn off the ID LED on all the compute nodes in the enclosure and enter the accept mode, in which the LED behavior is determined by the node ID LEDs.

    Table 1. SMM2 ID LED accept mode behavior

    Node identification LEDs	SMM2 identification LED
    All the node ID LEDs are off.	Off
    No node ID LED is blinking, but one or more node ID LEDs are on.	On
    One or more node ID LEDs are blinking.	Blink

    Note

    1. SMM2 ID LED is set in the accept mode by default.

    2. See the “Front LEDs and buttons / Node operator panel” section in Maintenance Manual/Setup Guide/User Guide of your solution for more information about node ID LEDs.

  • Turn On

    When this option is activated, all the node ID LEDs will be on except the blinking ones, which will remain blinking.

  • Blink

    When this option is activated, all the node ID LEDs will be blinking regardless of previous status.

• Check Log LED: Check Log LED will be on when an error event occurs. It will be turned off after the error event is de-asserted.

• FFDC: The Fast Failure Data Collection (FFDC) instantly collects information about events and conditions that might lead up to a failure. Click on Capture, and the file used to analyze the problem can be downloaded from the web.

• Enclosure Reseat: Click on Reseat, the enclosure will be powered off immediately and be powered on after 10 seconds.

  Note

  After you click on the button, Enclosure Reseat will go into effect immediately even when the nodes are still powered on.

• Open Source License: You can download the Open Source Licenses file that is used in Open Source packages in SMM2 by clicking on Download.

Current PSU (Power Supply Unit): Indicates the status of power supplies.

• Status

  • Present: The power supply is installed.

  • Not Present: No power supply is installed.

  • Fault: The power supply is in faulty condition.

• Ratings: Power rating, such as 1800 W, 2400 W, 2600 W, and 7200 W, is displayed here. Power rating varies by models, see solution system specifications for details.

• AC-IN: AC input power is displayed here.

• Capability: The maximum DC output power that the power supply can provide to the entire system is displayed here.

  • If DC-PG of the power supply is No, capability will be 0 W.

  • If DC-PG of the power supply is Yes, the capability will be equal to the lower output when power supplies with different wattages are installed in the enclosure at the same time.

• Zero-output:

  • Disabled: Zero-output is disabled.

  • Wake-Up: Zero-output is enabled. The power supply is in working state.

  • Sleep: Zero-output is enabled. The power supply is in hibernation with no DC output.

• EPOW (Early Power Off Warning)

  • Assert: The power supply is in input lost condition.

  • Normal: The power supply AC is working.

• Throttle

  • Assert: The power supply is in over-current condition.

  • Normal: The power supply is working.

• DC-PG (Direct Current - Power Good): The DC power status of the power supply.

  • No: The power supply is not providing the required DC power.

  • Yes: The power supply is providing required DC power.

Fan: Indicates the status of system fans. This section only applies to DA240 Enclosure.
