Remove the front PCIe adapter and riser card

Follow instructions in this section to remove the front PCIe adapter and riser 5 card.

About this task

Attention

  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

  • Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.

  • Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.

  • Before you remove any component of a RAID array (drive, RAID card, etc.), back up all RAID configuration information.

Procedure

  1. Make preparation for the task.
    1. If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top cover, or remove the server from the rack. See Remove the server from rack.
    2. Remove the top cover. See Remove the top cover.
    3. If your server comes with a riser 1 assembly, remove it first. See Remove a rear riser assembly. Then disconnect the cables from the rear OCP interposer card.
    4. Record the cable connections, and disconnect all cables from the system board assembly.
      Note

      • If you need to disconnect cables from the system board assembly, disengage all latches or release tabs on cable connectors first. Failing to release the tab before removing the cables will damage the cable sockets on the system board assembly. Any damage to the cable sockets might require replacing the processor board or system I/O board.

      • The connectors on your system board assembly might look different from those in the illustration, but the removal procedure is the same.

        1. Press the release tab to release the connector.

        2. Disengage the connector from the cable socket.

    5. Remove system fans. See Remove a system fan.
    6. Remove the system fan cage. See Remove the system fan cage.
  2. Remove the front adapter assembly.
    Note
    The number of cables varies according to the configuration.
