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.

Chapter 1
BPN-SAS-823T and BPN-SAS-823TQ 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 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-SAS-823T/TQ backplane.

• Disconnect the power cable before installing or removing any cables from the
BPN-SAS-823T/TQ backplane.

• Make sure that the BPN-SAS-823T/TQ backplane is securely and properly

installed on the motherboard to prevent damage to the system due to power
shortage.

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.

1-4 Introduction to BPN-SAS-823T/BPN-SAS-823TQ
Backplanes
The BPN-SAS-823T and BPN-SAS-823TQ backplanes have been designed to utilize the most up-to-date technology available, providing your system with reliable,
high-quality performance.
The BPN-SAS-823T backplane is identical to the BPN-SAS-823TQ backplane
except that the I2C connectors, sideband headers and the MG9072 chip are not
populated on the SAS823T backplane.
This manual reflects BPN-SAS-823T and BPN-SAS-823TQ Revision 1.00A, themost current release available at the time of publication. Always refer to theSupermicro Web site at www.supermicro.com for the latest updates, compatible
parts and supported configurations.

Figure 2-3: Front Jumpers (BPN-SAS-823TQ)

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 circuitboard. Note: On two pin jumpers, "Closed"means the jumper is on and "Open" means
the jumper is off the pins.

SAS Port Connections in I2C and SGPIO Modes
Remember the following when connecting this backplane:• In I C mode, I C #1 (JP44) corresponds with SAS ports #0, #1, #2, and #3. I C
222#2 (JP45) corresponds with SAS ports 4 and 5. If you connect the SAS ports
out of order, you will not able to easily identify drives using the LED function.

• In SGPIO mode, Sideband #1 (JP51) corresponds with SAS ports 0, 1, 2, and

3. Sideband #2 (JP52) corresponds with SAS ports #4 and #5. If you connect
the SAS ports out of order, you will not able to easily identify drives using the
LED function.
