Static Precautions
An electrostatic discharge (ESD) can damage disk drives, option boards, and other
components. You can ensure some ESD protection by wearing an anti-static wrist strap
attached to chassis ground when handling system components. Electronic devices can
be easily damaged by static electricity. To prevent damage, keep them in their
protective packaging when they are not installed in your system.
Equipment Log
Use the equipment log form located at the end of this manual to record the model and
serial number of your system, all the installed options, and any other pertinent
information specific to your system. You will need this information when configuring
your system.
Tools Recommended for Upgrading Your System
Depending on the upgrade, you will need one or more of the following tools:
- Phillips screwdriver (#1 bit and #2 bit)
- Flat-head screwdriver
- Small needle nose pliers
- Pen or pencil
- ESD workstation or anti-static wrist strap (recommended)
Preparing Your System for Upgrade
To prepare your system for installation or removal of system components perform the
following procedure:
1. Observe the safety and ESD precautions listed under “General Safety
Information” and “Static Precautions” at the beginning of this chapter.
2. Shutdown the operating system (OS).
3. If necessary, press the power on/off switch on the front panel of the system ( See
“Powering On your System” on page 112. ). The power-on LED goes out.
4. Power off the peripheral devices.
5. Unplug the system power cord(s) from the AC wall outlet(s).
Note: If the system power cord is connected to a power
control unit such as an UPS (Uninterruptible Power Supply),
refer to the UPS user's guide for proper power-off procedures.
6. Unplug all the I/O cables connected to the rear panel of your system.
