Remove an E3.S CMM cage and backplane

Follow the instructions in this section to remove an E3.S CMM cage and backplane.

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.

Procedure

  1. Make preparations for this 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 Server replacement.
    2. Remove all E3.S CMMs installed in the cage. See Remove an E3.S non-hot-swap CMM.
    3. Remove the top cover. See Remove the top cover.
    4. Remove the air baffle. See Remove the air baffle.
    5. Disconnect the power and signal cables from the processor board.
      Attention
      To avoid damaging the system board assembly, make sure to follow the instructions in Internal cable routing when disconnecting cables from the system board assembly.
  2. Remove the E3.S 2T cage.
    Note
    An E3.S bezel without inner plate is used to cover a space with E3.S 2T cage installed. For proper cooling and airflow, make sure to reinstall an E3.S 2T cage and corresponding E3.S bezel before turning on the server. If you use an E3.S bezel without inner plate to cover a space without E3.S 2T cage, server components might be damaged during operation.
