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
Make preparation for the task.
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.
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.
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 system board assembly.
The connectors on your system board assembly might look different from those in the illustration, but the removal procedure is the same.
Press the release tab to release the connector.
Disengage the connector from the cable socket.
Remove the front adapter assembly.
Note
The number of cables varies according to the configuration.
Figure 1. Removing the front adapter assembly
Remove the screws that secure the assembly.
Slide the assembly out of the front chassis.
Lift the riser 5 assembly up off the front OCP assembly, and disconnect cables from the front OCP interposer card.
Figure 2. Lifting the riser 5 assembly
Remove the PCIe adapter from the riser 5 cage.
Note
For ThinkSystem AMD X3522 10/25GbE DSFP28 2-port PCIe Ethernet Adapter, remove the screw that secures the adapter first.
Figure 3. Removing the PCIe adapter from the riser 5 cage
Press the retainer clip downward.
Rotate the retention latch to the open position.
Grasp the PCIe adapter by its edges and carefully pull it out of the PCIe slot.
Disconnect the cables from the riser card, and remove the riser card from the riser 5 cage.
Figure 4. Removing the riser card from the riser 5 cage
Remove the screws that secure the riser card.
Rotate the riser card from the top to disengage it from the screw holes on the riser cage.
Lift the riser card out of the riser cage.
After you finish
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.
