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 components. 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-
