Remove the PCIe riser

Follow the instructions in this section to remove the PCIe riser.

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.

Note
For more details on the different types of risers, see Rear view.
Depending on your configuration, follow the corresponding procedures below for proper removal procedure.

Remove PCIe riser 2​

Procedure

  1. If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top covers, or remove the server from the rack. See Server replacement.
  2. Remove the front top cover. See Remove the front top cover.
  3. Remove the rear top cover. See Remove the rear top cover.
  4. Remove the crossbar. See Remove the crossbar.
  5. Record the cable connections and disconnect all cables from the system board assembly. See
    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.
  6. If there are PCIe adapters installed, record the cable connections and disconnect cables from the backplanes.
  7. Grasp and lift the PCIe riser to remove it from the chassis..
