Step 3: Replace a PCIe card
To replace a PCIe card, you must remove the cabling and any QSFPs and SFPs from the ports on the PCIe
cards in the target riser, remove the riser from the controller module, remove and replace the PCIe card,
reinstall the riser and any QSFPs and SFPs onto the ports, and cable the ports.
1. Determine if the card you are replacing is from Riser 1 or if it is from Riser 2 or 3.
◦ If you are replacing the 100GbE PCIe card in Riser 1, use Steps 2 - 3 and Steps 6 - 7.
