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.  
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.

SAS-826A Backplane User’s Guide  
Introduction to the SAS-826A Backplane  
The SAS-826A backplane has been designed to utilize the most up-to-date technol-  
ogy available, providing your system with reliable, high-quality performance.  
This manual reflects SAS-826A Revision 1.00, the most current release available at  
com for the latest updates, compatible parts and supported configurations.

Chapter 1: Safety Guidelines  
Chapter 1  
SAS-826A 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 SAS-826A backplane.  
Disconnect the power cord before installing or removing any cables from the  
SAS-826A backplane.  
Make sure that the SAS-826A backplane is securely and properly installed on  
the motherboard to prevent damage to the system due to power shortage.

Pin Definitions (JP26)  
The activity LED headers, designated JP26  
and JP47, are used to indicate the activity  
status of each SAS drive. The activity LED  
headers are located on the front panel. For the  
activity lead headers to work properly, connect  
to them using a 10-pin LED cable. This is only  
used when the activity LED is not supported  
by the hard drive.

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.
