SAS2-846EL Backplane User's Guide
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 first for any product problems.

Safety Information and Technical Specifications
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 it very carefully. The following measures
are generally sufficient 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 motherboard to prevent damage to the system due to power shortage.

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.

Introduction to the SAS2-846EL Backplane
The SAS2-846EL backplane has been designed to utilize the most up-to-date technology available, providing your system with reliable, high-quality performance.
This manual reflects SAS2-846EL1 and SAS2-846EL2 PCB Revision 1.10, 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 configurations.
The SAS2-846EL1 backplane includes a primary expander chip and primary SAS
connectors. The SAS2-846EL2 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 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 identified 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.

Single and Dual Port Expanders
Single Ports
SAS2-846EL1 backplanes have a single-port expander that accesses all hard drives
and supports cascading.
Dual Ports
SAS2-846EL2 backplanes have dual-port expanders that access all the hard drives.
These dual-port expanders support cascading, failover, and multipath.

Failover with RAID Cards and Multiple HBAs
The SAS-836EL backplane may be configured 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 configured to perform
the load balancing and failover tasks.

Figure 3-5: Connecting an Internal HBA to the Backplane
IMPORTANT: See Section 3-3 of this manual, Failover with RAID Cards and Multiple
HBAs for important information on supported configurations.
Supported Internal HBA Cables
Use the following listed cables to create connections between the internal HBA and
SAS2-846EL backplane. The cables required depend on the HBA connector.
Cable Name: iPass TO 4-lane
Part #: CBL-0117L
Length: 46 cm (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 SAS2-846EL backplane.

Connecting an External Host Bus Adapter to the
Backplane
This backplane supports external Host Bus Adapters. In this configuration, the HBA
and the backplane are in different physical chassis. This allows a JBOD configuration system to connect to the other system that has a HBA.

Supported Cascading Configurations
Cascading allows the system to access data at a faster rate by allowing several
backplanes to share resources to reduce latency time.
The first backplane in a cascaded system requires a motherboard and an 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.
