Warnings
Read and adhere to all warnings, cautions, and notices in this guide and
the documentation supplied with the chassis, power supply, and accessory
modules. If the instructions for the chassis and power supply are inconsistent
with these instructions or the instructions for accessory modules, contact
the supplier to find out how you can ensure that your computer meets
safety and regulatory requirements.
Cautions
Electrostatic discharge (ESD) can damage system components. Do the
described procedures only at an ESD workstation. If no such station is
available, you can provide some ESD protection by wearing an antistatic
wrist strap and attaching it to a metal part of the computer chassis.

Preface
Installation Recommendations
Ensure you have a stable, clean working environment. Dust and dirt can get
into components and cause a malfunction. Use containers to keep small
components separated.
Adequate lighting and proper tools can prevent you from accidentally
damaging the internal components. Most of the procedures that follow
require only a few simple tools, including the following:
▪A Philips screwdriver
▪A flat-tipped screwdriver
▪A grounding strap
▪An anti-static pad
Using your fingers can disconnect most of the connections. It is recommended
that you do not use needle-nose pliers to disconnect connections as these
can damage the soft metal or plastic parts of the connectors.
Safety Information
Before installing and using the device, note the following precautions:
▪Read all instructions carefully.
▪Do not place the unit on an unstable surface, cart, or stand.
▪Follow all warnings and cautions in this manual.
▪When replacing parts, ensure that your service technician uses parts
specified by the manufacturer.
▪Avoid using the system near water, in direct sunlight, or near a heating
device.
▪The load of the system unit does not solely rely for support from the
rackmounts located on the sides. Firm support from the bottom is highly
necessary in order to provide balance stability.
▪The computer is provided with a battery-powered real-time clock circuit.
There is a danger of explosion if battery is incorrectly replaced. Replace
only with the same or equivalent type recommended by the manufacturer.
Discard used batteries according to the manufacturer’s instructions.
