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.

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.
Disconnect the signal cables from the system board assembly. See PCIe riser cable routing for more information.
Remove the PCIe riser.
1. If applicable, disconnect the power cable from the PCIe riser.
2. Grasp and lift the PCIe riser out of the chassis.

Record the cable connections and disconnect all internal cables from the PCIe adapters.

After you finish

If no PCIe riser is going to be installed to the chassis, install a riser filler into the chassis.
If you plan to replace a PCIe adapter, see Remove a PCIe adapter.
If you are instructed to return the component or optional device, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
