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.
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 first 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 components. To prevent dam-
age 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 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 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 SAS2-826EL Backplane
The SAS2-826EL backplane has been designed to utilize the most up-to-date tech-
nology available, providing your system with reliable, high-quality performance.
This manual reflects SAS2-826EL Revision 1.01, the most current release available
cro.com for the latest updates, compatible parts and supported configurations.
1-5 Overview of the SAS2-826EL1/EL2 Backplanes
The SAS2-826EL1 and SAS2-826EL2 model backplanes are identical, except that
the SAS2-826EL2 backplane has duplicate secondary components which are not
found on the SAS2-826EL1. The SAS2-826EL2 is divided into a two sections, with
the primary components on the right side of the board and the secondary compo-
nents on the left.

Connector
Pins
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.

3-3 Failover with RAID Cards and Multiple HBAs
The SAS2-826EL 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.
Dual Host Bus Adapter

In a dual host bus configuration, the
backplane connects to two host bus

3-5 Supported Cascading Configuration
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 HBA. Other
servers require a power control card, not a motherboard and HBA.

Other Considerations:
•
•
•
Cascading supports up to one hundred twenty-two hard drives
Use the same cables for all single port configurations
See page 3-7 if your HBA is external to your backplane.
