Power on the hardware for EF50 and EF80 storage systems

After cabling your EF50 or EF80 storage system, you power on the shelves and assign shelf IDs (if applicable) and power on the controllers.

Before you begin

Take anti-static precautions.

Step 1: Power on the shelves and assign shelf IDs

Power on the shelves and then assign unique shelf IDs to each shelf.

About this task

  • Assigning a unique shelf ID to each shelf ensures that the shelf is distinct within your storage system.

    A valid shelf ID is 01 through 99.

    Internal shelves (storage), which are integrated within the controllers, are assigned a fixed shelf ID of 00.

  • You must power cycle a shelf (turn off the power switch on each of the power supplies of the SAS shelf, wait at least 10 seconds, and then switch the power back on) for the shelf ID to take effect.

Steps

  1. Power on the shelf by connecting the power cords first to the shelf, securing them in place with the power cord retainer, connecting the power cords to power sources on different circuits, and then turning on the power switch on each of the power supplies (at the rear of the shelf).

    The shelf powers on and boots automatically when powered on.

  2. Remove the left end cap to access the orange shelf ID button on the faceplate.

  3. Change the first number of the shelf ID:

    1. Press and hold the shelf ID button until the first number on the digital display blinks, and then release the button.

      It can take up to 15 seconds for the number to blink. This activates the shelf ID programming mode.

      Note If the ID takes longer than 15 seconds to blink, press and hold the shelf ID button again, making sure to press it in all the way.

    2. Press and release the shelf ID button to advance the number until you reach the desired number from 0 to 9.

      Each press and release duration can be as short as one second.

      The first number continues to blink.

  4. Change the second number of the shelf ID:

    1. Press and hold the button until the second number on the digital display blinks.

      It can take up to three seconds for the number to blink.

      The first number on the digital display stops blinking.

    2. Press and release the shelf ID button to advance the number until you reach the desired number from 0 to 9.

      The second number continues to blink.

  5. Lock in the desired number and exit the programming mode by pressing and holding the shelf ID button until the second number stops blinking.

    It can take up to three seconds for the number to stop blinking.

    Both numbers on the digital display start blinking and the amber LED illuminates after about five seconds, alerting you that the pending shelf ID has not yet taken effect.

  6. Power-cycle the shelf for at least 10 seconds to make the shelf ID take effect.

    1. Turn off the power switch on each of the power supplies.

    2. Wait 10 seconds.

    3. Turn on the power switch on each of the power supplies to complete the power cycle.

      When a power supply is powered on, the bicolored LED should illuminate green.

  7. Replace the left end cap.

Step 2: Power on the controllers

After you've powered on your shelves and assigned them unique IDs, power on the controllers.

  1. Plug a power cable into each controller power supply, and then connect them to power sources on different circuits.

    Note If you are using third-party power distribution units (PDUs), do not use power outlets directly behind the controllers because you might block access to the controllers.

    • The system begins to boot. Initial booting might take up to eight minutes.

    • The LEDs on the system chassis flash and the fans start, which indicates that the controllers are powering on.

      During start-up it is normal for the fans to be very loud.

    • The digital display on the front of the system chassis (behind the bezel) does not illuminate.

  2. Secure the power cords using the securing device on each power supply.

After powering on your storage system, complete storage system setup.
