DANGER: Multiple power cords. The product might be equipped with multiple AC power cords
or multiple DC power cables. To remove all hazardous voltages, disconnect all power cords and
power cables. (L003)
4. 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.
5. For a rack-mounted system, open the side latches (A) and pull the latches to slide the system unit fully
into the service position until the slides click and hold the system unit securely. Ensure that the screws
inside the latches are not secured to the rack.
See the following figure.
Remove the hook-and-loop fasteners that secure the cable management arms. Ensure that the cable
management arms can move freely. Ensure that the cables at the rear of the system do not catch or
bind as you pull the system unit into the service position.
Do not pull out or install any drawer or feature if the rack stabilizer brackets are not attached to the
rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out
more than one drawer at a time.
