4.4.15 PCIe riser replacement
This procedure works for the first and second PCIe risers. To replace the third PCIe riser (which also
contains the I/O port module), refer to “I/O port module (third PCIe riser) replacement” on
page 4-16.
To replace a PCIe riser:
1. Power down the system.
2. Disconnect the system from power.
3. If there is a PCIe card in the riser, disconnect any external cables to the card.
4. Remove the rear top cover.
Note:
If there is a PCIe card in the riser, it might be easiest to remove the card after removing
the riser from the chassis.
5. If you are replacing the riser closest to the side of the chassis, remove the screw that secures
riser bracket to the chassis.
6. Adjust the black plastic latch on the rear of the chassis to release the riser.
7. Disconnect cables from the PCIe riser.
8. Lift the PCIe riser out of the socket on the motherboard.
