Replace the Ethernet I/O module - NS224 shelves with NSM100B modules

You can replace a failed Ethernet I/O module nondisruptively in an NS224 drive shelf that is powered on, and while I/O is in progress. This procedure only applies to NS224 shelves with NSM100B modules.

Before you begin

  • The shelf's partner NSM must be up and running, and be cabled correctly so that your shelf maintains connectivity when you remove the failed NSM.

  • All other components in the system must be functioning properly.

About this task

  • Allow at least 70 seconds between removal and installation of the NVMe shelf module (NSM).

    This allows enough time for ONTAP to process the NSM removal event.

  • Best practice: The best practice is to have current versions of NVMe shelf module (NSM) firmware and drive firmware on your system before replacing FRU components.

    Note

    Do not revert firmware to a version that does not support your shelf and its components.

  • Shelf (NSM) firmware is automatically updated (nondisruptively) on a new NSM that has a non-current firmware version.

    NSM firmware checks occur every 10 minutes. An NSM firmware update can take up to 30 minutes.

  • If needed, you can turn on the shelf's location (blue) LEDs to aid in physically locating the affected shelf: storage shelf location-led modify -shelf-name shelf_name -led-status on

    If you do not know the shelf_name of the affected shelf, run the storage shelf show command.

    A shelf has three location LEDs: one on the operator display panel and one on each NSM. Location LEDs remain illuminated for 30 minutes. You can turn them off by entering the same command, but using the off option.

  • When you unpack the replacement NSM, save all packing materials for use when you return the failed NSM.

    If you need the RMA number or additional help with the replacement procedure, contact technical support at NetApp Support, 888-463-8277 (North America), 00-800-44-638277 (Europe), or +800-800-80-800 (Asia/Pacific).

Steps

  1. Properly ground yourself.

  2. Disconnect the cabling from the NSM that contains the FRU that you are replacing:

    1. Disconnect the power cord from the power supply by opening the power cord retainer if it is an AC power supply, or unscrewing the two thumb screws if it is a DC power supply, and then unplug the power cord from the power supply.

      Power supplies do not have a power switch.

    2. Disconnect the storage cabling from the NSM ports.

      Make a note of the NSM ports that each cable is connected to. You reconnect the cables to the same ports when you reinsert the NSM, later in this procedure.

  3. Remove the NSM:

    Remove the NSM.
    Callout number 1

    On both ends of the NSM, push the vertical locking tabs outward to release the handles.
    Callout number 2

    • Pull the handles towards you to unseat the NSM from the midplane.

      As you pull, the handles extend out from the shelf. When you feel some resistance, keep pulling.

    • Slide the NSM out of the shelf and place it on a flat, stable surface.

      Make sure that you support the bottom of the NSM as you slide it out of the shelf.
    Callout number 3

    Rotate the handles upright (next to the tabs) to move them out of the way.

  4. Remove the failed I/O module from the NSM:

    Replace the I/O module.
    Callout number 1

    Turn the I/O module thumbscrew counterclockwise to loosen.
    Callout number 2

    Pull the I/O module out of the NSM using the port label tab on the left and the thumbscrew.

  5. Install the replacement I/O module into the target slot:

    1. Align the I/O module with the edges of the slot.

    2. Gently push the I/O module all the way into the slot, making sure to properly seat the module into the connector.

      You can use the tab on the left and the thumbscrew to push in the I/O Module.

    3. Turn the thumbscrew clockwise to tighten.

  6. Insert the NSM into the shelf:

    Replace the NSM.
    Callout number 1

    If you rotated the NSM handles upright (next to the tabs) to move them out of the way while you serviced the NSM, rotate them down to the horizontal position.
    Callout number 2

    Align the rear of the NSM with the opening in the shelf, and then gently push the NSM using the handles until it is fully seated.
    Callout number 3

    Rotate the handles to the upright position and lock in place with the tabs.

  7. Recable the NSM.

    1. Reconnect the storage cabling to the same two NSM ports.

      Cables are inserted with the connector pull-tab facing up. When a cable is inserted correctly, it clicks into place.

    2. Reconnect the power cord to the power supply, and then secure the power cord with the power cord retainer if it is an AC power supply, or tighten the two thumb screws if it is a DC power supply, and then unplug the power cord from the power supply.

      When functioning correctly, a power supply's bicolored LED illuminates green.

      Additionally, both NSM port LNK (green) LEDs illuminate. If a LNK LED does not illuminate, reseat the cable.

  8. Verify that the attention (amber) LEDs on the NSM containing the failed I/O module and the shelf operator display panel are no longer illuminated

    The NSM attention LEDs turn off after the NSM reboots and no longer detects an I/O module issue. This can take three to five minutes.

  9. Verify that the NSM is cabled correctly, by running Active IQ Config Advisor.

    If any cabling errors are generated, follow the corrective actions provided.
