Servicing the GPU Module

If you are removing the entire GPU cage, be aware of the following considerations.

Note

If you are removing or installing the GPU cards themselves, these considerations do not apply.

• Each GPU slot has an MCIO cable. One end of the cable connects to the GPU cage, and the other end

connects to a socket on the mezzanine PCB.

• The slots on the Front mezzanine GPU module numbered 1 or 2. Although cables and connectors are

not labeled, you can use these slot numbers to help identify which cable must be connected to which

front mezzanine slot.

• Cables are not labeled, so make sure that you don't mix up the connections, such as connect the cable

for slot 2 to slot 1.

• Before disconnecting cables, you will find it helpful to mark which cable connects to GPU 1 and which

cable connects to GPU 2.

• If you are working with both GPU cables, do the following to allow more room for your fingers:

• When you are installing cables, make sure that you route them so that they do not pinch, bind, or interfere

with the removal or installation of other parts.

• When installing a GPU cage, always connect the GPU-cage end of the cable first, then connect the

mezzanine PCB-end of the cable.

• When removing a GPU cage, always disconnect the PCB-end of the cable first before detaching the

GPU-cage end of the cable.

• In most cases, you can leave the cables connected at the front mezzanine end and disconnect cables from

just the GPU end. However, if you must disconnect the front mezzanine end of the cable, the MCIO

connectors are labeled on the front mezzanine PCB to help identify how to reconnect the cables.
