Power on the storage system - AFF A1K

After you install the rack hardware for your AFF A1K storage system and install the cables for the controllers and storage shelves, you should power on your storage shelves and controllers.

Step 1: Power on the shelf and assign shelf ID

Each shelf is distinguished by a unique shelf ID. This ID ensures that the shelf is distinct within your storage system setup.

About this task

  • A valid external shelf ID is 01 through 99.

    If you have internal shelves (storage), which are integrated within the controllers, they are assigned a fixed shelf ID of 00.

  • You must power cycle a shelf (unplug both power cords, wait the appropriate amount of time, and then plug them back in) 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, and then connecting the power cords to power sources on different circuits.

    The shelf powers on and boots automatically when plugged into the power source.

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

  3. Change the first number of the shelf ID:

    1. Insert the straightened end of a paperclip or narrow tipped ball point pen into the small hole to press the shelf ID button.

      Note On DS series shelves, the shelf ID button is accessible directly at the bottom of the shelf ear.

    2. 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.

    3. 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, or 1 to 9 if the system has onboard storage.

      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. Unplug the power cord from both power supplies on the shelf.

    2. Wait 10 seconds.

    3. Plug the power cords back into the shelf power supplies to complete the power cycle.

      A power supply is powered on as soon as the power cord is plugged in. Its bicolored LED should illuminate green.

  7. Replace the left end cap.

Step 2: Power on the controllers

After you've turned on your storage shelves and assigned them unique IDs, turn on the power to the storage controllers.

Steps

  1. Connect your laptop to the serial console port. This will allow you to monitor the boot sequence when the controllers are turned on.

    1. Set the serial console port on the laptop to 115,200 baud with N-8-1.

      Note See your laptop's online help for instructions on how to configure the serial console port.

    2. Connect the console cable to the laptop, and connect the serial console port on the controller using the console cable that came with your storage system.

    3. Connect the laptop to the switch on the management subnet.

      Console connections

    4. Assign a TCP/IP address to the laptop, using one that is on the management subnet.

  2. Plug the power cords into the controller power supplies, and then connect them to power sources on different circuits.

    Generic power connection diagram

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

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

    • The fans might be very noisy when they first start up. The fan noise during start-up is normal.

  3. Secure the power cables using the securing device on each power supply.
