7 Replace Internal M.2 Flash SSDs

This section describes how to service M.2 flash solid-state drives (SSDs).

M.2 flash SSDs are replaceable components that do not require you to power off the server before servicing. For more information about replaceable components, see Illustrated Parts Breakdown and Replaceable Components.

Caution:

These procedures require that you handle components that are sensitive to electrostatic discharge. This sensitivity can cause the component to fail. To avoid damage, ensure that you follow antistatic practices, as described in Electrostatic Discharge Safety.

Caution:

Unless the two M.2 risers are running in a software RAID configuration, removing one riser might result in a system crash and possible data corruption.

Caution:

The lever is not an ejector. Do not open the lever too far. Doing so can damage the lever.

Flash Riser Board

Remove

The server can contain up to two hot-pluggable flash riser boards (SSDR0, SSDR1). Each flash riser board can contain one M.2 flash SSD.

  1. Prepare the server for service.
    1. Extend the server into maintenance position. See Extend the Server to the Maintenance Position.
    2. Attach an antistatic wrist strap to your wrist, and then to a metal area on the chassis. See Take Antistatic Measures.
    3. Remove the server top cover. See Remove the Server Top Cover.

Hot service requires component replacement within 60 seconds.

  1. To remove the flash riser board, do the following:
    1. Rotate both riser board socket levers outward as far as they go.

      Note:

      The green Power LED indicator located on the riser board is extinguished when you open the socket levers.
    2. Carefully lift the riser board straight up to remove it from the sockets. Place the riser board on an antistatic mat. If required, perform the procedures for removing the M.2 flash SSD from the flash riser board. See "Identify and Remove an M.2 Flash SSD".

Install

The system motherboard provides two slots (labeled SSDR 0 and SSDR 1) for flash riser boards. When installing flash riser boards, install the first riser board into slot SSDR 0 and then into SSDR 1.

  1. Unpack the replacement flash riser board and place it on an antistatic mat.If required, ensure that you have installed an M.2 flash SSD onto the riser board before installing the riser board into the server. See "Install an M.2 Flash SSD".
  2. Install the flash riser board.
    1. Ensure that the riser board socket levers are in the open position.
    2. Align the notch in the replacement riser board with the connector key in the connector socket. The notch ensures that the riser board is oriented correctly.
    3. Push the riser board into the connector socket until the riser board is securely seated in the socket.

Caution:

If the riser board does not easily seat into the connector socket, verify that the notch in the riser board is aligned with the connector key in the connector socket. If the notch is not aligned, damage to the riser board might occur.
    1. Rotate the riser board socket levers inward until the riser board is secured in place.
  2. (Optional) Repeat Step 2 to install a second flash riser board into the server.
  3. Return the server to operation.
    1. Install the server top cover. See Install the Server Top Cover.
    2. Return the server to the normal rack position. See Return the Server to the Normal Rack Position.

M.2 Flash SSD

Identify and Remove

In the standard Oracle Communications Server E6-2L configuration, the flash riser board contains an M.2 flash SSD in a socket.

  1. Prepare the server for service.
    1. Extend the server into maintenance position. See Extend the Server to the Maintenance Position.
    2. Attach an antistatic wrist strap to your wrist, and then to a metal area on the chassis. See Take Antistatic Measures.
    3. Remove the server top cover. See Remove the Server Top Cover.
  2. Identify and note the location of the failed M.2 flash SSD.
    1. Identify the location of the failed M.2 flash SSD.

      Failed SSDs are identified with a corresponding amber LED that is lit on the flash riser board.

      • If the SSD fault LED is off, then the SSD is operating properly.
      • If the SSD fault LED is on (amber), then the SSD is failed and must be replaced.

      The amber SSD fault LED indicator [1] and green Power LED indicator [2] are illuminated only when power is applied to the system. The green Power LED indicator is extinguished when you open the riser board socket levers.

    2. Note the location of the failed M.2 flash SSD. Note the faulty SSD location, before replacing the cover, if removing system power for cold service.
  3. Remove a flash riser board from the server.
  4. Place the riser board on an antistatic mat.
  5. Remove the M.2 flash SSD in socket SSD from the riser board.
    1. Using your fingers, push the plastic retainer clip through the flash riser board to release the M.2 flash SSD from the riser board [1].

    2. Remove the plastic retainer clip from the M.2 flash SSD [1].
    3. Lift up on the end of the M.2 flash SSD where the plastic retainer clip was removed by one-half to one inch [2].
    4. Gently slide the M.2 flash SSD card back and out of the connector to disengage the SSD contacts from the riser board socket [2].
    5. Place the M.2 flash SSD on an antistatic mat.

Install

In the standard Oracle Communications Server E6-2L configuration, the flash riser board contains an M.2 flash SSD in a socket.

  1. Unpack the replacement M.2 flash SSD and place it on an antistatic mat.
  2. Install the M.2 flash SSD into socket SSD on the flash riser board.
    1. Align and then insert the plastic retainer clip into the slot on the M.2 flash SSD [1].
    2. Hold the M.2 flash SSD so that the end of the card containing the plastic retainer clip is approximately one-half to one inch above the riser board, and the other end is adjacent to the riser SSD socket [1].

    3. Gently slide the M.2 flash SSD forward and into the connector to engage the flash SSD contacts with the riser board socket [2].
    4. Using your fingers, push down on the end of the card containing the plastic retainer clip until the M.2 flash SSD snaps into place on the riser board [2].You hear an audible click when the M.2 flash SSD is secured to the flash riser board.
  3. Perform the steps to install the M.2 flash riser board with the replacement flash SSD into the server. See "Install a Flash Riser Board".
  4. Return the server to operation.
    1. Install the server top cover. See "Install the Server Top Cover".
    2. Return the server to the normal rack position. See "Return the Server to the Normal Rack Position".
