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 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.

1-3 Version
The BPN-SAS3-836EL 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 SAS3-836EL1 and SAS3-836EL2 Revision 1.01, the most
current release available at the time of publication. Always refer to the Supermicro
Web site at www.supermicro.com for the latest updates, compatible parts and sup-
portedcongurations.
All images and layouts in this user's guide are based upon the latest PCB revision
available at the time of publishing. The backplane you have received may not look
exactly the same as the graphics in this manual.

2-3. SAS Connectors
The primary and secondary sets of SAS connectors provide expander features
including cascading and failover.
4-5. Expander Chips
These primary and secondary expander chips allow the backplane to support
dual ports, cascading, and failover.
6-10. I2C Connector, UART Connectors, SDB Connectors
The I2C connector, the UART connectors, and the SDB connectors are for manu-
facturing diagnostic purposes only.
11. SMB Connector
This header provides for a connection with an optional JBOD controller board.
12. OVERHEAT_FAIL2 Connector
This header can be connected to an external overheat LED, if desired.

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.

Dual Port and Cascading Congurations
3-1 Single and Dual Port Expanders
SAS connectors PRI-J0 to J3 and SEC-J0 to J3 are bidirectional and can be treated
as input or output.
Single Ports
BPN-SAS3-836EL1 backplanes have a single port expander that accesses all of
the drives and supports cascading.

Dual Ports
BPN-SAS3-836EL2 model backplanes have dual-port expanders that access all
of the hard drives. These dual-port expanders support cascading, failover, and
recovery.

Single Host Bus Adapter
In a single host bus conguration, the
backplane connects to one host bus
adapter.
The BPN-SAS3-836EL2 model backplane has two expanders which enable effec-
tive failover and recovery.
3-2 Failover

Failover
If the expander or data path in Port A
fails, the system automatically switches
to Port B with application software or
failover support.

Failover
If the expander or data path in Port
A fails, the system automatically
switches to Port B. This maintains
a full connection to all drives.

Important: For RAID controllers, redundancy is achieved through port failover. For
multiple HBAs MPIO software is required to achieve failover protection.
3-3 Failover with RAID Cards and Multiple HBAs
TheBPN-SAS3-836EL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

CSE-PTJBOD-CB3 Control Board
Allows the chassis to be used as
a JBOD (Just a Bunch of Disks)
system, which supports IPMI for
remote on/off control.
In a cascaded conguration, the rst chassis includes a motherboard and at
least one host bus adapter (HBA). Other JBODs in this enclosed system must be
equipped with a control card. This section describes the supported control board
for the BPN-SAS3-836EL series backplane.
