Procedure
1. Attach the electrostatic discharge (ESD) wrist strap.
The ESD wrist strap must be connected to an unpainted metal surface until the service procedure is
completed, and if applicable, until the service access cover is replaced.
Attention:
• 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.
• 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.
• 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. Remove the fans.
For instructions, see "Removing a system fan from the 9006-22P" on page 34.
3. Remove the center PCIe riser.
Label and disconnect the cables from the PCIe adapters. Keep the PCIe adapters in the risers. For
instructions, see Removing a PCIe adapter in the system.
