Preface
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
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 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 BPN-SAS2-826EL series backplane.
• Make sure that the backplane is properly and securely on the motherboard to
prevent damage to the system due to power outages.

1-3 An Important Note to Users
All images and layouts shown in this user's guide are based upon the latest back-
plane 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 the BPN-SAS2-826EL Backplane
The SAS2-826EL backplane has been designed to utilize the most up-to-date
technology available, providing your system with reliable, high-quality performance.
ThismanualreectsSAS2-826ELRevision1.01,themostcurrentreleaseavailable
at the time of publication. Always refer to the Supermicro Web site at www.supermi-
cro.comforthelatestupdates,compatiblepartsandsupportedcongurations.
1-5 Overview of the BPN-SAS2-826EL1/EL2 Backplanes
The BPN-SAS2-826EL1 and BPN-SAS2-826EL2 model backplanes are identical,
except that the BPN-SAS2-826EL2 backplane has duplicate secondary components
which are not found on the BPN-SAS2-826EL1. The SBPN-SAS2-826EL2 is divided
into a two sections, with the primary components on the right side of the board and
the secondary components on the left.

2-3 Rear 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.

New versions of these backplanes no longer support a buzzer. We recommend
using the LSI MegaRAID Storage Manager or a similar management application
to trigger an email alert instead.
The buzzer alarm is triggered by one of the following conditions:
• Hard drive failure
• Fan failure
• System temperature over 45º Celsius.

3-3 Failover with RAID Cards and Multiple HBAs
TheBPN-SAS2-826ELbackplanemaybeconguredforfailoverwithmultipleHBAs
using either RAID controllers or HBAs to acheive failover protection.
RAID Controllers: If RAID controllers are used, then the failover is accomplished
through port failover on the same RAID card.
HBAs: If multiple HBAs are used to achieve failover protection and load balancing,
LinuxMPIO softwaremust beinstalled andcorrectly conguredto perform
the load balancing and failover tasks.
IMPORTANT: For RAID controllers, redundancy is achieved through port failover.
For multiple HBAs, MPIO software is required to achieve failover protection.
