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.
