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.
â—¦ If you are replacing the 100GbE PCIe card in Riser 1, use Steps 2 - 3 and Steps 6 - 7.
â—¦ If you are replacing a PCIe card from Riser 2 or 3, use Steps 4 through 7.
2. Remove Riser 1 from the controller module:
a. Remove the QSFP modules that might be in the PCIe card.
b. Rotate the riser locking latch on the left side of the riser up and toward the fan modules.
The riser raises up slightly from the controller module.
c. Lift the riser up, shift it toward the fans so that the sheet metal lip on the riser clears the edge of the
controller module, lift the riser out of the controller module, and then place it on a stable, flat surface.
