Preface

Returning Merchandise for Service
A receipt or copy of your invoice marked with the date of purchase is required before any warranty service will be rendered. You can obtain service by calling yourvendor for a Returned Merchandise Authorization (RMA) number. When returning
to the manufacturer, the RMA number should be prominently displayed on theoutside of the shipping carton, and mailed prepaid or hand-carried. Shipping andhandling charges will be applied for all orders that must be mailed when service
is complete.
For faster service, RMA authorizations may be requested online (http://www.supermicro.com/support/rma/).
Whenever possible, repack the backplane in the original Supermicro box, using theoriginal packaging materials. If these are no longer available, be sure to pack the
backplane in an anti-static bag and inside the box. Make sure that there is enoughpackaging material surrounding the backplane so that it does not become damaged
during shipping.
This warranty only covers normal consumer use and does not cover damages incurred in shipping or from failure due to the alteration, misuse, abuse or improper
maintenance of products.
During the warranty period, contact your distributor first for any product problems.

Chapter1: Safety Guidelines

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

Electrostatic 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 backplane 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 motherboard to prevent damage to the system due to power shortage.

Explanation of Jumpers

Connector
Pins

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 theconnector. Pin 1 is identified with a square
solder pad on the printed circuit board. Note:
On two pin jumpers, "Closed" means thejumper is on and "Open" means the jumper
is off the pins.
