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.
Locate the disk and fan signal cable(A). It connects from the system backplane to the disk drive and fan card, along the inside of the system.
See Figure 1. Figure 1. Location of the disk and fan signal cable and
connectors
Release the cable from the retaining clip on the inside wall of the system.
Label and disconnect the disk and fan signal cable(A) from the disk drive and fan card(B) and from the system backplane(C).
Using your thumb, press the release latch on the connector to remove a cable. See Figure 2. Figure 2. Removing the disk and fan signal cable
