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 dam-
age 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 antistatic
bag.
• Handle the RAID card by its edges only; do not touch its components, peripheral
chips, 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 backplane.
• Disconnect the power cable before installing or removing any cables from the
backplane.
• Make sure that the backplane is securely and properly installed on the mother-
board 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.

2-3 Front Jumper Locations and Pin Definitions
Explanation of Jumpers
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 function
of the connector. Pin 1 is identified with
a square solder pad on the printed circuit
board. Note: On two pin jumpers, "Closed"
means the jumper is on and "Open" means
the jumper is off the pins.
