Attention:
v
Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack, or to
an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging
your hardware.
v When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is
used for static control. It does not increase or decrease your risk of receiving electric shock when
using or working on electrical equipment.
v If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging and
installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of
5 seconds. If at any point in this service process you move away from the system, it is important to
again discharge yourself by touching an unpainted metal surface for at least 5 seconds before you
continue with the service process.
2. Unplug the GPU power cable (A) from the system backplane as shown in Figure 22. Using your
thumb, press the release latch on the connector to remove the cable.
3.
The GPU can share the PCIe riser card with other PCIe adapters. Label and remove any cables and
plugs that extend out of the adapters.
4. Remove the PCIe riser as shown in Figure 23 on page 25.
a. Retract the retaining pins (A) so that the arrows on the tabs point to the system.
b. Lift the PCIe riser from the system.
