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 your vendor
for a Returned Merchandise Authorization (RMA) number. When returning to themanufacturer, the RMA number should be prominently displayed on the outside of
the shipping carton, and mailed prepaid or hand-carried. Shipping and handlingcharges 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 thebackplane 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.

Guidelines

Chapter 1Guidelines

This chapter offers guidelines for personal and equipment safety, and notes about
the BPN-SAS3-216A-N4 version documented in this manual.

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 thebackplane.

• Make sure that the backplane is securely and properly installed on the mounting
frame in the chassis to prevent damage to the system due to power shortage.

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 functionof the connector. Pin 1 is identified witha 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.
