Figure 6: PCB Cable Connectors, HHHL GPU
While performing some tasks, you will need to disconnect these cables. When disconnecting cables, you must
disconnect the ends opposite the riser cages.
• For the power cable, disconnect the end that connects to the base PCBA.
• For the MCIO cables, disconnect the end that connects to the rear mezzanine PCB.
GPU Cables
Each full height full length (FHFL) GPU requires a separate cable that connects the GPU directly to a socket
on the riser cage. This cable is the GPU auxiliary (AUX) power cable, and it is different from the riser cables
described in the preceding section.
While performing some tasks for an FHFL GPU (for example, replacing a FHFL GPU), you must disconnect
this cable. It is a best practice to disconnect the GPU AUX power cable from the riser socket, not the GPU,
unless otherwise documented.
Removing Riser, Type A
Each PCIe node can contain a maximum of two PCIe riser cages of the same type. Use this procedure to
remove a Type A riser.
Step 1
Remove the PCIe node from the server.
See
Removing the PCIe Node, on page 12
Step 2
Remove the top cover.
See
Removing a PCIe Node Cover, on page 18
.
Step 3
Detach the riser cage from the PCIe node.
a) Using a #2 Phillips screwdriver, loosen the three captive thumbscrews.
