Remove a PCIe riser

Follow instructions in this section to remove a 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.
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 rails.

Note

Depending on the configuration, follow the corresponding procedures below for proper removal procedure:
The PCIe riser location might look different from the illustrations in this topic.

Procedure

Make preparation for this task.
1. Remove the front top cover. See Remove the front top cover.
2. Remove the rear top cover. See Remove the rear top cover.
3. If the serial port module is installed, slightly lift the PCIe riser, and disconnect the serial port cable from the system board assembly.
  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.
Disconnect the signal cables from the system board assembly. See PCIe riser cable routing for more information.
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.
If applicable, disconnect the power cable from the PCIe riser.
Grasp and lift the PCIe riser out of the chassis.
