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.
supermicro.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.

Preface
Overview of the BPN-SAS2-216EL1/EL2 Backplanes
The BPN-SAS2-216EL1/EL2 model backplanes consists of a BPN-SAS2-216EB
backplane (X) with one or two BPN-SAS2-216EL daughter cards (Y and Z) mounted
on the rear of the backplane.
The BPN-SAS2-216EL1 model consists of the BPN-SAS2-216EB backplane (X)
and one BPN-SAS2-216EL primary daughter card (Y), mounted on the right-hand
side of the backplane.
The BPN-SAS2-216EL2 model consists of the BPN-SAS2-216EB backplane (X)
with a BPN-SAS2-216EL primary daughter card mounted on the right (Y) and a
BPN-SAS2-216EL secondary daughter card mounted on the left (Z).
Components on the front side of the BPN-SAS2-216EB backplane include twenty-
four SAS connectors and their respecitve activity and failure LEDs. Components
on the rear side of the backplane include jumpers and power and fan connectors.
Thedaughtercard'scomponentsincludeSASports,ashandexpanderchips,and
mode select jumpers.

Chapter 1 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 the backplane 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 and daughter cards by their edges only; do not touch the
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 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 mother-
board to prevent damage to the system due to power shortage.

2-3 Jumper Locations and Settings
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.
