• 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.

For stand-alone systems, the recommended service position for working with the system backplane
is to lay the system on its side. You do not need to lift the system. For instructions to place a stand-
alone system in the service position, continue to step "17" on page 11.
CAUTION: This system requires two people to tip the system onto its side.
