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 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 in­curred in shipping or from failure due to the alteration, misuse, abuse or improper
maintenance of products.

During the warranty period, contact your distributor fi rst for any product problems.

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 com ponents. To prevent dam­age to your system, it is important to handle it very carefully . The following measures
are generally suffi 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 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 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 the SAS2-847EL Backplane

The SAS2-847EL backplane has been designed to utilize the most up-to-date tech­nology available, providing your system with reliable, high-quality performance.

This manual refl ects SAS2-847EL1 and SAS2-847EL2 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 sup­ported confi gurations.

The SAS2-847EL1 backplane includes a primary expander chip and primary SAS
connectors. The SAS2-847EL2 includes of both primary and secondary expander
chips, as well as primary and secondary SAS connectors. The primary and second­ary expanders are redundant, so that if one should fail, the other will take over.

Figure 2-2: Front Jumper Locations and Pin Defi mitions

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 identifi 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.

3-3 Failover with RAID Cards and Multiple HBAs

The SAS-836EL backplane may be confi 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 confi gured to perform
the load balancing and failover tasks.

SAS HBA

Dual Host Bus Adapter

In a Dual Host Bus Confi guration, the
backplane connects to two Host Bus
Adapters.

Dual Host Bus Adapter
Failover

If the expander or data path in the
primary ports fails, the system auto­matically switches to the secondary
ports. This maintains a full connection
to all drives. Note that this confi gura-
tion requires additional MPIO software.
Contact your Supermicro authorized
representative for details.

Supported Internal HBA Cables

Use the following listed cables to create connections between the internal HBA and
SAS2-847EL backplane. The cables required depend on the HBA connector.

Cable Name: iPass TO 4-lane
Part #: CBL-0117L Length: 46cm (18 inches)

Description: This cable has one SFF-8484 (32 pin) connector on one end and

iPass (SFF-8087/mini-sas) connector (36 pins) at the other. This cable connects
from the HBA to the SAS2-847EL backplane.

Cable Name: SAS EL2/EL1 Cascading Cable (External), 68cm
Part #: CBL-0166L

Ports: Single or Dual

Description: External cascading cable. Connects ports between servers. Use one

cable for single port connections and two cables for dual port connections.

Placement: External cable

3-4 Supported Cascading Confi gurations

Cascading allows the system to access data at a faster rate by allowing several
backplanes to share resources to reduce latency time.

The fi rst backplane in a cascaded system requires a motherboard and HBA. Other
servers require a power control card with no motherboard and no HBA. For more
information, see the SC846 Chassis Manual available at www.supermicro.com.
