Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is required be-

fore any warranty service will be rendered. You can obtain service by calling your

vendor for a Returned Merchandise Authorization (RMA) number. When returning to

the manufacturer, the RMA number should be prominently displayed on the outside

of the shipping carton, and mailed prepaid or hand-carried. Shipping and handling

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.super-

micro.com/support/rma/).

Whenever possible, repack the backplane in the original Supermicro box, using the

original 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 enough

packaging 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 in-

curred in shipping or from failure due to the alteration, misuse, abuse or improper

maintenance of products.

Duringthewarrantyperiod,contactyourdistributorrstforanyproductproblems.

Chapter 1: Safety Guidelines

Chapter 1

BPN-SAS3-827HQ 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 com ponents. To prevent dam-

age to your system, it is important to handle it very carefully. The following measures

are generally sufcient 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 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 backplane 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 BPN-SAS3-827HQ backplane.

•Disconnect the power cable before installing or removing any cables from the

BPN-SAS3-827HQ backplane.

•Make sure that the BPN-SAS3-827HQ backplane is securely and properly

installed on the motherboard 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 function

of the connector.Pin 1 is identied 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.

2-5 SAS Ports

The BPN-SAS3-827HQ backplane is designed with four separate nodes, which sup-

port from one to four motherboards indepentdently of each other. The SAS ports are

used to connect the SAS drive cables. The 24 ports are designated A0, A1, A2, A3,

A4, A5, B0, B1, B2, B3, B4, B5, C0, C1, C2, C3, C4, C5, D0, D1, D2, D3, D4, and

D5. Each port is also compatible with SATA drives. Use the table below to deter-
