Safety Information and Technical Specifications

Chapter 1
Safety Guidelines

To avoid personal injury and property damage, carefully follow all the safety steps
listed below when accessing your system or handling the components.

1-1

ESD Safety Guidelines

Electric Static Discharge (ESD) can damage electronic components. To prevent damage to your system, it is important to handle it very carefully. The following measures
are generally sufficient to protect your equipment from ESD.
•Use a grounded wrist strap designed to prevent static discharge.

•Touch a grounded metal object before removing a component from the antistaticbag.

• Handle the RAID card by its edges only; do not touch its components, peripheralchips, memory modules or gold contacts.
• When handling chips or modules, avoid touching their pins.
• Put the card and peripherals back into their antistatic bags when not in use.

1-2•

General Safety Guidelines
Always disconnect power cables before installing or removing any components
from the computer, including the SAS 825TQ Backplane.

• Disconnect the power cable before installing or removing any cables from theSAS 825TQ Backplane.
• Make sure that the SAS 825TQ Backplane is securely and properly installedon the motherboard to prevent damage to the system due to power shortage.

1-3•An Important Note to Users
All images and layouts shown in this user's guide are based upon the latest
PCB Revision available at the time of publishing. The card you have received
may or may not look exactly the same as the graphics shown in this manual.

To modify the operation of the backplane,
jumpers can be used to choose between
optional settings. Jumpers create shorts
between two pins to change the functionof the connector. Pin 1 is identified witha square solder pad on the printed circuitboard. Note: On two pin jumpers, "Closed"means the jumper is on and "Open" meansSetting
