Procedure
1. Attach the electrostatic discharge (ESD) wrist strap.
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.
2. Remove the power riser air baffle. Using the blue tabs (A), unsnap the baffle and lift it from the
system. See Figure 115.

3. Label and remove the fan power cable from the power distribution card. For instructions, see
"Removing the fan power cable from the 8335-GTB" on page 48.
4. Remove the power distribution cards. For instructions, see "Removing a power riser from the
8335-GTB" on page 81.
5. Remove the BMC card. For instructions, see "Removing the BMC card from the 8335-GTB" on page
93.
6. Label and remove the graphics processing units (GPUs). For instructions, see "Removing the
graphics processing unit from an air-cooled 8335-GTB system" on page 60. You will need to place
them on an ESD surface.
7. Label and remove the PCIe adapters. For instructions, see "Removing a PCIe adapter from the
system backplane in the 8335-GTB" on page 79.
