System status LED not blinking

If you are using the USB flash drive to initialize the system for the first time and the status LED is not blinking, use the following instructions to resolve this issue.

About this task

If the system status LED on the node canister that you are initializing is not blinking at a regular rate, the system cannot be initialized until this condition is resolved. The regular rate of blinking for the system status LED is approximately one half second on and one half second off. Complete the following steps until the system status LED is blinking at the regular rate:
Note: Unless stated, all the checks and actions are completed on the rear of the enclosure. Do not disturb any wiring or other equipment while you complete these tasks.

Procedure

  1. Ensure that you are looking at a control enclosure of the system that you want to initialize and not a different machine type or an expansion enclosure.
    The following diagrams show the rear of the control enclosure based on the model type of your control enclosure:

    Figure 2. Rear view of a model 2076-312 or a model 2076-324 control enclosureThis figure shows the rear view of a model 2076-312 or a model 2076-324 control enclosure.
    •  1  Power supply unit 1
    •  2  Power supply unit 2
    •  3  Node canister 1
    •  4  Node canister 2
    •  5  10 GB Ethernet ports (models 2076-312 and model 2076-324 only)
    A control enclosure has an upper and lower node canister. The upper canister  3  is top side up, and lower canister  4  is inverted, or top side down. The control enclosure also has two power supply units, one on the right side of the enclosure and the other on the left. The canisters in the control enclosure can be distinguished from the canisters in an expansion enclosure by the extra Ethernet ports, USB ports, and LEDs. When determining ports and LEDs, ensure that you are looking at the correct canister. If this is the correct enclosure, proceed to step 2

    If this is not the correct control enclosure, determine where the correct control enclosure is installed. Click Cancel and continue with the system initialization wizard on the correct control enclosure.The system can be comprised of multiple control enclosures. System initialization only needs to occur on one control enclosure.

  2. Ensure that the node canister is powered on by locating the power LED indicators ( 1 ) on the node canister that you are initializing.
    This image shows the rear of the control enclosure with node canister LEDs highlighted.
    The green power LED (This icon shows the power LED.) should be permanently on (not blinking or off). If the green power LED is on, continue to the Step 3.

    If the power LED on the node canister is blinking, the canister is still powering on. However, if the power LED is blinking for five minutes after you applied power to the enclosure, there is a problem with the canister. See Resolving problems with a node canister for information.

    If the power LED is off, check the power indicators ( 1 ) on the power supply unit.
    Figure 3. LEDs on the power supply units of the control enclosureThis figure shows the LEDs on the power supply units of the control enclosure.
    If both the ac failure LED (This icon shows the ac power LED on the power supply unit.) and the dc failure LED (This icon shows the DC power LED on the power supply unit.) are lit on the power supply unit, you need to replace the power supply unit before you initialize the system. Contact your hardware service representative for a new power supply unit.

    If this is the case and you have multiple control enclosures attached to the system, you can click Cancel and restart the initialization using one of the other control enclosures.

  3. On the node canister, check that the system status LED (This icon shows the system status LED on the node canister.) is on permanently. If the system status LED is on permanently, proceed to the next step. The system status LED is not lit until the system has completed the first stage of initialization. The initialization can take up to ten minutes from when power is applied to the system. If power has been on for at least ten minutes and the system status LED is still off, there is a problem with the canister. See Resolving problems with a node canister for information. Wait for the status LED to change to blinking or for the ten minutes to be up.
  4. On the node canister, check the system status LED (This icon shows the system status LED on the node canister.) .

    If the system status LED is not permanently on at this point, return to the first step in this process. If you are following these instructions to re-initialize a system that you have already used, see Resolving a problem topics in the Troubleshooting section of the Information Center to determine the status of the system and how to fully reset the system.

    To work with the initialized system, open a supported Web browser and enter the IP address that you specified during the initialization wizard. Log on to the system and continue with system configuration by completing the system setup wizard.

    Note: If you have a single control enclosure, only one of the canisters in the enclosure needs to be initialized. The other node canister is added automatically after the system completes initialization. If you have multiple control enclosures, you also only need to initialize one canister on one of the control enclosures. The other control enclosure can be added to the system during system setup.
