CAUTION: Hazardous moving parts nearby. (L008)
Power off the system and place it in the service position. For instructions, see "Preparing the 9006-12C
system to remove and replace internal parts" on page 78.
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:
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. Lift the holder for the fans as shown in Figure 16. The fans are easier to remove when the holder is
slightly lifted.
