Disconnect the system from its power source and from any
telecommunications links, networks or modems before
doing any of the procedures described in this chapter.
Failure to disconnect power, telecommunications links,
networks or internal modems before you open the system
or do any procedures can result in personal injury or
equipment damage.

CAUTIONS
The total power draw on the system must not exceed the
specifications for the power supply. See Chapter 7 for the
power supply specifications.
Electrostatic discharge (ESD) can damage disk drives, add-in
boards, and other components. Conduct the procedures
described in this chapter only at an ESD workstation. If
such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching
it to a metal part of the system chassis.
Add-in boards can be extremely sensitive to ESD and always
require careful handling. After removing the board from its
protective wrapper or from the system, place the board flat
on a grounded, static-free surface, component-side up. Use
a conductive foam pad if available, but not the board
wrapper. Do not slide the board over any surface.
